The classification of gas alarms can be divided into: combustible gas alarms, toxic gas alarms and composite gas alarms. Gas alarms use different sensors to detect different gases. Composite gas alarms can detect flammable and toxic gases at the same time. .
According to the use environment, it can be divided into: industrial gas alarms and household gas alarms.
According to its own form, it can be divided into: fixed gas alarm and portable gas detector.
Principle of gas alarm
Just like the parameter description of the flammable and poisonous gas controller model modeled by Sinoguan Company
Product features of the gas alarm controller: &Using a high-speed processor, it can Process system tasks quickly and accurately to ensure system reliability
&The gas alarm LCD screen can display the status in real time
&The flammable gas alarm uses communication protocols and has high reliability
& Set of programmable relays, passive normally open and normally closed contacts, contact capacity/
&The alarm adopts a modular structure design to facilitate system maintenance
&Can realize local monitoring through the computer, and the status data can be Permanent storage
& Combustible gas, high precision, strong reliability
& Four-wire bus structure
& Explosion-proof design suitable for hazardous conditions, areas
Large sound and light alarm The screen has an LCD display and a friendly interface. It has the functions of automatic node search, software zero adjustment, software calibration, and alarm point setting. It adopts communication protocols and transmits data reliably.
