USES:
Suitable for underground coal mine with gas explosion, dust explosion dangerous places, can be used in smoke, CH4, CO and other combustible gas over limit alarm, smoke signal and smoke over limit monitoring.
Product features:
The sensor is a high-precision combustible gas/voltage converter, V/V conversion, voltage comparator, controllable alarm and output circuit composed of MQ214 dedicated smoke sensor. MQ214 sensor output smoke signal is proportional to the voltage signal, through the voltage comparator and digital circuit processing output smoke overlimit alarm signal. It has the characteristics of easy setting, high sensitivity, high precision, free from calibration, stable and reliable work, etc.
