Household sensor gas analyzer. Home gas analyzer

• Close to gas burners(1m).
• In places of heavy pollution (dust, grease, ashes).
• Near ventilation ducts.
• Where paint, solvent and combustible materials are stored.

Periodic examination

At least once a year, it is necessary to conduct a survey of the gas analyzer performance.

Gas analysis is required in the most different areas where it is important to have an idea about the composition and characteristics of combustible air mixtures. At home, gas analyzers, or detectors, are more often used to detect leaks. Moreover, the target environment can be not only a domestic gas pipeline. This may be an air conditioning system with freon, and a boiler plant with harmful emissions. A modern gas analyzer is presented in different versions, which differ in the principle of operation, control system, performance characteristics and other parameters.

Features of household gas analyzers

Models for home use are distinguished by their small size, modest performance and simplified operation. If professional devices involve stationary operation, then the household device provides the ability to move. Its functionality is designed to search for leaks with the examination of gas vapors at different points. At the same time, in the segment of home devices there are different levels functional content. For example, a household gas analyzer from the budget category works with the simplest warning system, which can be represented by a light or sound indication. That is, if the apartment has an excess of gas vapor concentration relative to the standard value, the detector will give an appropriate signal, but without additional information. More complex household models are equipped with a display that reflects data with detailed characteristics of the medium under study.

Varieties of the detector

Home analyzers of gas mixtures are presented in manual and automatic versions. In the first case, this is a simple absorption apparatus, the principle of operation of which is based on the process of absorption of gas vapors by reagents. These are inexpensive and at the same time affordable devices that demonstrate an average level of analysis accuracy. Automatic models are characterized by wider possibilities for studying target environments. In particular, a gas analyzer of this type can continuously monitor certain parameters of a mixture or its individual component. As for the principle of operation, it can be based on the principle of physical analysis, chemical reactions or physico-chemical process. With the help of an automatic detector, the user determines such indicators as the pressure and volume of the mixture, the concentration of oxides, etc.

Installation of gas analyzers

In household analyzer families, there are also stationary models that require a special installation. At the same time, they are also distinguished by their compact size, unpretentious maintenance and low performance. Installation of such a device is usually carried out in a place of increased risk of gas leakage. This may be the area next to the boiler or stove. Mounting is most often carried out on the wall in such a way that the user has the possibility of direct access to the control panel of the device. The gas analyzer is fixed using a mounting profile, which is usually included in the basic kit. Using screws or self-tapping screws, it is necessary to install the carrier panel, and the device itself is already integrated into it. Depending on the type of model, it may be necessary to run a power cable from the mains, although household low-power analyzers are more likely to run on batteries and batteries.

Nuances of operation

Work begins with the definition of the mixtures to which the device will be oriented. Modern devices allow you to configure the sensing elements to monitor various parameters of mixtures. The main setting refers to the determination of the upper and lower levels of the gas concentration. Special attention during operation should be given to the diagnostics of the device. Approximately once every six months, gas analyzers are calibrated, which consists in a comprehensive examination of the device with a test of its working qualities. V without fail are estimated on which the error of the obtained values ​​depends. Usually, verification is performed by switching the device to the appropriate mode, after which the test mixtures are analyzed by sensors. Next, a reconciliation of the obtained indicators with the normative ones is performed. Depending on the received data on the error, it may be necessary to perform a calibration, which is most often carried out automatically.

Manufacturers and prices

Gas analyzers are not widely used metrological instruments, therefore their development and production are mainly carried out by specialized companies. The best of them include Rothenberger, CEM, Testo and Mastech. Decent quality models from the MEGEON line are popular in the Russian segment. Detectors differ significantly in price - it depends on many parameters. A simple gas analyzer for the home with minimum set functions can cost about 2-3 thousand rubles. Average devices with a display are already estimated at 5-7 thousand. Multifunctional indicators with high-tech sensors can cost 15-20 thousand rubles.

Conclusion

Detectors that serve to detect leaks and spills in residential buildings are increasingly being considered as components of integrated security systems. In classical signaling circuits, such devices are introduced into a single control center for electrical engineering with the ability to program functions. This means that the gas analyzer can automatically adapt to work in specific conditions. We can say that even in a separate mode of operation, a modern automatic detector makes it possible to program. But they expand these possibilities, since the controller controls the parameters of the analyzer, guided by data from many other sensors and sensors.

Gas emergency shutdown system

The gas contamination detector (gas analyzer) is the primary device in systems emergency shutdown gas. It is he who analyzes the environment for exceeding the established norms of gas concentration and generates control signals for solenoid gas valves. Almost any analyzer is equipped with a system of noise and light warning of danger by default.

Depending on the purpose and place of operation, gas analyzers can monitor the excess concentration of:

• domestic gas GOST 5542 (methane, CH4)
• carbon monoxide
• propane
• butane

Household gas alarms manufactured by FSUE "Almaz" SPC "Gazotron S" for installation in apartments, residential buildings already come with a controlled valve. For larger facilities, gas analyzers are most often sold separately so that you can choose the right kit for your gas facilities yourself.

We remind you that the installation of gas alarms, as well as should be carried out only by specialists with the appropriate permission !!

Heating with fuel-burning units is convenient, economical and efficient. Leakage of combustible gas or combustion products is undesirable during the use of the boiler.

A household gas detector (or sensor) is a device that monitors the quality of the ambient air in the boiler room. When a dangerous concentration of harmful substances in the air accumulates, the signaling device is triggered: it turns on sound and light alarms, turns off the gas supply and stops the combustion of fuel in the boiler.

Installing such a sensor will protect the owners from the accumulation of gas in the room and help to eliminate the leak in time.

The signaling device can send a signal to a mobile phone (if there is a GSM module and connected to the subscriber's number).

Purpose of gas detectors

Gas detectors are installed in rooms where accumulation of harmful substances is possible. Conventional gas analyzers are capable of detecting accumulations of carbon monoxide, propane and natural gas (methane).

Carbon monoxide (CO) is a substance released during the combustion of fuels and can be deadly when released in an enclosed area.

Methane (CH4) is the main element of natural gas, which is supplied through the central gas pipeline. When it accumulates, an explosion and fire can occur (even from the smallest spark).

Propane (C3H8) is the main element of a liquefied propane-butane mixture, which is heavier than air, so even with an open window, gas may accumulate in the lower part of the room.

Design and principle of operation of gas detectors

The operation of gas detectors is based on various sensors: thermomechanical, optical or electromechanical. All gas analyzers consist of certain elements:

• The sensor is a sensitive element that senses and calculates the gas concentration in the ambient air.
• The measuring and indicating module is a system that perceives the signal of the primary converter and compares it with the set value.
• The power supply is a system for providing electrical power to the device.
• Instrument case.

Functionality of gas detectors:

• Light and sound alarm.
• Shut off the gas supply with a solenoid valve.
• Turn on the exhaust device.
• Signaling to a fire or control panel.

Types of gas detectors

The main difference between gas analyzers is the type of gas captured. The most common household alarms are gas analyzers for:

• carbon monoxide;
• methane;
• propane.

Combined gas analyzers capable of capturing several types of gas at once.

Household signaling fans

One of the types of localization of the accumulation of harmful substances in the boiler room is the installation of an exhaust fan, which turns on at the signal of the gas analyzer and provides forced ventilation.

Shut-off valves

The electromagnetic shut-off valve is used to instantly stop the flow of gas at the signal of the gas analyzer. There are various valves:

• By pipeline diameter.
• Electrical.
• with acceptable pressure.
• Differing in design.

There are 2 types of construction: normally open and normally closed.

They have the following differences:

• The normally open valve is cocked manually, and during operation it is not energized. In the event of a gas analyzer triggering, an electrical impulse is applied to close the valve. The valve is marked - “NA”;
• The normally-closed solenoid valve is also manually reset, but for this it is necessary to ensure the supply of electricity. During operation, it is constantly energized, and at the signal of the gas analyzer, the voltage disappears and the valve closes.

For domestic purposes, it is best to use normally open valves, since the absence of voltage will not affect their operation.

Cost of solenoid shut-off valve: type N.A., 220 V, Pmax: 500 mbar:

Operation of gas detectors

It is better to mount gas analyzers to a vertical plane where gas leakage can occur (near a boiler, furnace, gas meter, gas column).

Do not place the gas analyzer in the following places:

• Close to gas burners (1m).
• In places of heavy pollution (dust, grease, ashes).
• Near ventilation ducts.
• Where paint, solvent and combustible materials are stored.

When installing the sensor, the physical properties of the gas and its density should be taken into account:

• Methane - not lower than 0.5 m from the floor.
• Carbon monoxide - at a height of 1.8 m from the floor, but not higher than 0.3 m to the ceiling.
• Propane not higher than 0.5 m from the floor.
• Combined sensor for methane and carbon monoxide - in the range of 0.5-0.3 m to the ceiling.

To ensure uninterrupted operation of solenoid valves, it is necessary to install batteries with an automatic transfer to backup power.

The passport of the gas analyzer describes all the functions and requirements for operation, and their observance will allow to achieve reliable operation of the equipment.

Gas analyzer installation

Installation of the device does not require much effort, it can be mounted on dowels or screws. The passport of the device contains a diagram for connecting the electrical power to the device and connecting it to the rest of the equipment.

Installation of solenoid valves on the gas pipeline must be carried out only by a qualified specialist.

Periodic examination

At least once a year, it is necessary to conduct a survey of the gas analyzer performance.

Brands of gas alarms

Gas detectors are a guarantee safe operation boiler that runs on any type of fuel. When buying a unit, it is better not to save on such auxiliary equipment as an alarm.

Home Gas Leak Sensor: Household Gas Alarm | "Crown"

Domestic gas explosions in Russia do not surprise anyone. Almost every week, the media reports tragic cases related to this dangerous type of fuel. In 2015, 15 emergencies occurred in Russia, as a result of which 17 people died. In 2016, the situation worsened: in the first three months, employees of the Ministry of Emergency Situations recorded 10 similar cases.

Experts name several reasons for the disappointing trend:

1. System errors in Russian legislation. Negligence of officials and lack of proper control of in-house gas equipment.
2. Depreciation of intra-house gas communications. A device for detecting gas leaks can solve the problem, and in the long term - replacing old communications.
3. Violation of the rules for the operation of gas appliances.
4. Human factor. Boiling water hits the burner. The fire goes out. Household gas analyzer is absent, and after a while the gas fills the room. The slightest spark leads to tragedy. The second scenario - the hostess turns off the gas on the stove, and it goes out.

Among other reasons - a malfunction of the gas stove, errors in the design of the smoke exhaust system. The gas enters slowly, and a person sitting in the next room does not feel bad smell. But the gas leak sensor instantly signals an emergency situation and avoids trouble.

How to check for a gas leak at home?

The most common leak points are threaded connections, welds, valves.

Method number 1. soap solution

Gas leak: how to determine? You will need a sponge laundry soap and water. After creating a soapy emulsion, apply it to the site of the alleged leak. Often, leak detection foam can pinpoint exactly where the pipe is leaking. Leakage signals are inflated air bubbles.

Method number 2. Smell

Go outside for a few minutes and then return to the kitchen. The presence of an odor indicates a leak. What does a gas leak smell like? The fuel smells of ethyl mercaptan, an additive that has a specific smell.

Approach the pipe joints. If gas is leaking from the hose connections, you will hear a characteristic hissing sound. An additional symptom is yellowing of the leaves. indoor plants. With a small leak, household members may experience a headache.

If you don't know how to check a gas leak at home, don't trust internet users who recommend checking fittings with matches. Bring matches to gas pipes Absolutely forbidden. There is a known case when a pensioner, smelling a smell, lit a match “for testing”, after which she received severe burns of her hands and face.

Modern gas leak detector with alarm for home

There is an easier way to secure your home - install a gas detector. This is a small device that continuously monitors the concentration of combustible gases in a room. Its task is to inform the user about the excess of the value of the controlled parameter of its limit value.

Home appliances respond to:

1. Propane.
2. Methane.
3. Carbon monoxide.

There are combined models. The task of the sensors is not to determine the degree of gas contamination of the room, but to warn of a leak in time. The equipment will give a signal much earlier than the gas concentration reaches an explosive value.

A gas leak detector with an alarm for a home can be:

1. Semiconductor. It is based on the interaction (diffusion) of atoms. When the active substance (carbon or tin) comes into contact with carbon monoxide, an alarm mechanism is triggered.
2. Catalytic. In electrochemical sensors, the sensitive substance is the electrolyte, and its action is based on the oxidation process. It is launched by gas molecules in contact with the electrode.
3. Infrared (IR). Such a household gas leak detector is considered the most reliable. The incoming air is checked for gas content by means of infrared radiation.

Devices are also divided into wired and wireless.

The gas leak alarm can also perform other functions:

• send an alarm signal to the relay to start the exhaust fan;
• shut off the gas supply (this will require the installation of shut-off valves - a special shut-off valve);
• send an alarm signal to the control panel of the security company.

The last feature requires detailed consideration.

Household remote control gas leak detector

The main disadvantage of traditional sensors is that the owner can hear the alarm signal only if he himself is in the apartment. If there is no one in the apartment, and there is no one to take emergency measures, the concentration of gas in the kitchen will increase. This flaw is easily solved by connecting to a gsm alarm device.

How can you detect a gas leak while at work or on vacation?

Combine the sensor with the alarm system. When the analyzer is triggered, the sensor sends a signal to the owner of the apartment via gsm communication, and also informs the security headquarters about the gas contamination. Employees of the service company arrive at the site within a few minutes and eliminate the danger.

Advantages of the kits:

1. No false positives, 100% elimination of leakage.
2. Control of the object in 24/7 mode.
3. Maintenance free. It is enough to wipe the grate from dust and cobwebs.
4. Possibility of integration with security system, fire detectors and water leakage control devices.
5. Mobile phone control.

When you already know how to check a gas stove for gas leaks, and how serious the consequences of a leak can be, it's time to think about installing sirens. The cost of special sensors will pay off with your peace of mind and the health of loved ones.

Household gas analyzer: types, characteristics, purpose

The gas analysis procedure is needed in various fields where it is required to know about the composition and characteristics of combustible air mixtures. At home, it is carried out to detect leaks.

The environment can be not only a household gas pipeline, but also an air conditioning system with freon, a boiler plant. The household gas analyzer exists in various versions. They have different operating principles, control systems, characteristics.

For the safety of the house, such a device must be in place.

Instrument features

The device has specific characteristics, because it is intended for a special branch of security - detection of gas leaks. Among the variety of devices there are equipment with different functions.

The household carbon monoxide gas analyzer has small parameters, modest performance and simple operation. If professional devices are operated stationary, then household devices can be moved.

The main function of the gas analyzer is the search for leaks in the study of gas vapors.

Home devices have different functions. For example, an inexpensive household gas analyzer has a simple warning system. This function can manifest itself in the form of light or sound indication.

If the concentration of gas vapors is increased in the apartment, the device will give a signal. Sophisticated devices have displays on which detailed information is indicated.

Thanks to them, convenient management is provided.

Types of detectors

The household gas analyzer can be manual and automatic, which determines the convenience of work. In the first case, the device is presented in the form of an absorption apparatus, which operates on the principle of absorption of gas vapors by reagents. These devices are inexpensive and easy to use. They show the average level of accuracy of the analysis.

Automatic devices have a variety of possibilities. They can operate continuously, controlling the parameters of the mixture and its individual components. Based on physical analysis, chemical reactions or physico-chemical process. Parameters such as pressure, volume of the mixture, concentration of oxides are set in the automatic detector.

There is a portable gas analyzer that has small parameters. It is easy to use and easy to set up. Any type of leak will be immediately noticeable. The portable gas analyzer is ideal for all areas. Its functions do not differ from the standard device.

Installation Features

A household gas analyzer can be stationary, so it must be installed. It has compact size, convenient maintenance and low performance. Install such a device in an area of ​​\u200b\u200bhigh risk of gas leakage. This may be a place with a boiler installation, a stove or a boiler.

Mounting occurs on the wall so that users have access to control. Fixing is carried out with a fixing profile, which is included in the kit. With screws or self-tapping screws, you need to install the carrier panel, and then the device itself is attached.

Sometimes a power cable is required, but many low-power devices operate on batteries. There are different household gas analyzers for apartments with gas stoves. Each of them has its own characteristics.

Before using the device, please read the operating instructions. There is a manual for this device.

Subtleties of operation

It is necessary to start work by determining the mixtures with which the device will work. Many instruments can function with sensing elements to track different mixtures. The main setting is to determine the level of gas concentration.

Diagnostics of the device is of great importance. Every six months it is necessary to check the devices. The procedure consists in examining the gas analyzer and testing its performance. Metrological characteristics, which determine the error of values, are necessarily controlled.

The check is carried out by transferring the device to a special mode, after which the sensors do their job. Then reconciliation of indications with the norm is carried out. Calibration may be required, which is performed automatically.

Foreign manufacturers

There is a household gas analyzer with a gas shut-off device, which is very convenient to use compared to standard appliances. Devices are produced by specialized companies. The best ones are:

• Rothenberger;
• testo;
• Mastech.

Russian manufacturers. Prices

On the Russian market Megeon brand devices are popular. Detectors also differ in cost, which is determined by different characteristics. An ordinary gas analyzer with a small set of functions costs about 2-3 thousand rubles. If there is a display, then the device has a cost in the range of 5-7 thousand rubles. Multifunctional devices have a price tag of 15-20 thousand rubles.

When choosing a device, it is necessary to take into account the type of gases being studied. Devices can work with combustible gases, for example, butane, natural gas. The detector can only be configured for one substance. It must be suitable for the purpose - the search for leaks and exhaust analysis.

It is important to pay attention to the temperature range. If you work outside, then you should choose a device that can withstand temperatures up to -20 degrees. Gas analyzers for boiler houses, laboratories and production are now being sold.

Detectors that can be used to detect gas leaks are quality systems security. In conventional signaling schemes, these devices enter the control room.

It turns out that the device can automatically adjust to different conditions. In a separate mode, the detectors can be programmed.

But in a complex, security systems work more extensively, since the controller controls the parameters of the analyzer using many different sensors and sensors.
