GWSD100/100 Mining intrinsic safety temperature and humidity sensorDetailed product description：

The GWSD100/100 intrinsically safe temperature and humidity sensor for mining (hereinafter referred to as the sensor) is an intrinsically safe instrument for mining and is a new product independently developed by our company.

Main functions of GWSD100/100 intrinsically safe temperature and humidity sensor for mining
It is mainly used for continuous temperature and humidity detection in the underground environment of coal mines (such as mine working face, mining area entrance, return airway, and emergency shelter system), in order to monitor the occurrence of fires. It can also be used for temperature and humidity measurement in other places. In addition to being used in conjunction with our KJ70 coal mine monitoring system, the sensor can also be compatible with other coal mine monitoring systems; It can also be independently used in various mining fire detection systems.

Environmental conditions for the use of GWSD100/100 intrinsically safe temperature and humidity sensor for mining
The temperature and humidity sensor should be able to operate normally under the following environmental conditions:
a) Environmental temperature: 0 ℃ to+40 ℃;
b) Average relative humidity: not exceeding 95% (+25 ℃);
c) Atmospheric pressure: 80kPa~106kPa;
d) There are explosive environments such as gas and coal dust underground in coal mines;
e) Places without strong vibrations and impacts;
f) A place without corrosive gases that can damage metals and insulation materials.
