Product Description
This product is a home usage combustible gas leakage detector. The product uses high stability semiconductor gas sensor and it is processed by high quality chip to protect you away from fire. When it detects the leaking combustible gas, once it reaches it's alarm sensitivity, it gives out both sound alarm and LED indicator to warn you that the gas is leaking.The detector is widely used in indoor places where the gas possibly leaks.
Application
With the development of society, people's sense of safety is becoming stronger and stronger. In recent years, gas alarm has been widely used in gas, petroleum, chemical industry, steel, metallurgy, water conservancy and other industries. The use of gas alarm with appropriate loudness greatly reduces the probability of major accidents due to gas leakage in places where gas equipment is used.
In terms of function, gas leakage alarm can be divided into leakage alarm with only leakage alarm function and detection alarm with alarm function that can indicate the detected gas concentration; From the place of use, it can be divided into civil gas leakage alarm and commercial alarm. Civil alarm is usually an independent gas alarm used in residence, with simple function; Commercial alarms are mainly used in transportation and storage places of gas, factories and public places where gas is used and there may be gas leakage. The Urban Gas Code stipulates that gas alarms shall be installed in basements, semi basements, gas rooms in aboveground confined spaces, building pipe wells, closed meter rooms, etc. Civil gas leakage alarm is also recommended in relevant codes and regulations of buildings and gas.
Gas leakage alarm is a very important gas safety equipment. It is the last protection for the safe use of urban gas. The gas leakage alarm detects the low concentration combustible gas in the surrounding environment through the gas sensor, and transmits the detection signal to the controller or control circuit with analog or digital quantity through the sampling circuit. When the combustible gas concentration exceeds the value set in the controller or control circuit, The controller sends an alarm signal or performs actions such as closing the gas valve through the actuator or executive circuit. Combustible gas alarm sensors for detecting combustible gas mainly include oxide semi conducting type, catalytic combustion type, hot wire type gas sensors, and a small number of other types, such as chemical battery sensors. These sensors produce chemical reaction or electrochemical reaction on the surface of the sensor through the adsorption of combustible gas in the surrounding environment, resulting in the change of the electro-physical characteristics of the sensor.
