What is a gas detector? what's the effect?

A combustible gas detector is a detector that responds to the concentration of single or multiple combustible gases. The combustible gas detector has two types of catalytic type and infrared optical type. The catalytic flammable gas detector measures the flammable gas concentration by using a change in resistance after heating of the refractory metal platinum wire. When the combustible gas enters the detector, an oxidation reaction (flameless combustion) is caused on the surface of the platinum wire, and the heat generated causes the temperature of the platinum wire to rise, and the resistivity of the platinum wire changes. The infrared optical type uses an infrared sensor to detect the alkane combustible gas in the field environment by the absorption principle of the infrared light source. In many industries, it is necessary to pay attention to flammable gas in real time, because in the event of an accident, the consequences are very serious. Let us take a look at the features of the gas detector today.
The combustible gas alarm adopts high-tech, high intelligence and wide transmission, fully preventing the accident and ensuring the safety of life and property. When the customer's flammable gas alarm receives and receives abnormal data in the surrounding environment, it will notify the family members of the gas leak in the form of a buzzer alarm within 3 seconds, so as to prevent the problem before it occurs.
And the customer gas detector in Europe collects the on-site gas concentration in real time and judges whether the alarm value is exceeded. If the concentration exceeds the limit, the detector will emit an audible and visual alarm signal and control the electromagnetic valve in parallel.
In addition, the customer gas alarm can be linked to the home alarm host for better cloth/disarming operations.
