Gas alarm important role!

Gas alarms, also known as gas leak detection alarms, mainly include flammable and toxic gas detection alarms. When the daily alarm environment (such as the kitchen using natural gas) or flammable or toxic gas leaks in the industrial environment, when the gas alarm detects that the gas concentration reaches the alarm value set by the alarm device, the alarm device emits sound and light alarm signals. To remind people to take evacuation, forced ventilation, shut down equipment and other safety measures to prevent explosions, fires, poisoning accidents, thus ensuring safe production. It is often used in chemical plants, petroleum, gas stations, steel mills, etc. where flammable gases are used or generated.

Combustible gas alarms are mainly used to detect combustible gases in the air. Common gases such as hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propyne (C3H4), butyne (C4H6), phosphine (PH3) and the like. Toxic gas alarms are used to detect toxic gases in the air such as hydrogen sulfide (H2S), carbon monoxide, sulphur dioxide, chlorine, etc.

Combustible gas alarm consists of sensors (probe), instrument host (controller), and alarm devices. The instruments mainly include detection components, amplifier circuits, alarm systems, and displays. When the flammable gas occurs and exists in the tested site, the sensor (probe) of the flammable gas alarm reacts, and the gas signal is converted into a voltage signal or a current signal and transmitted to the instrument host (controller). The instrument host displays a combustible gas explosion. The lower limit of the percentage concentration value and provides an alarm signal. Toxic gas alarm, its measurement principle is the electrochemical principle, usually contains toxic gas in the air, it completely has the possibility of poisoning Kang, hydrogen sulfide as an example, if people in a 100PPM concentration environment , there will be obvious symptoms of poisoning. It can be seen how important the gas alarm is in people's daily life and work. Therefore, for the sake of safety, it is necessary to purchase an appropriate alarm and avoid many accidents and ensure the safety of life.
