GWK42 Mining intrinsic safety temperature sensorDetailed product description：

The GWK42 mining intrinsic safety temperature sensor is suitable for use in environments containing gas, coal dust, and explosive gases underground in coal mines. It can be used in conjunction with the main unit of the mining explosion-proof and intrinsic safety belt conveyor protection control device or the main unit of the mining automatic sprinkler dust reduction device. Detect and protect the temperature of the reducer high-speed shaft, motor casing, transmission drum bearing seat, etc. of the coal mine underground belt conveyor belt, and it can also be used in non explosion proof areas on the ground where there is a belt conveyor.

Main parameters of GWK42 mining intrinsic safety temperature sensor
Rated operating voltage: 12V.DC, operating voltage range: (11-24) V.DC;  
Operating temperature: 42 ℃± 2 ℃;  
Restoration temperature: 37 ℃± 2 ℃;  
Response time: ≤ 60s
Action performance: When the temperature value of the measured point reaches the action temperature, the output normally open contact closes and the red light goes out; When the temperature value of the measured point reaches the recovery temperature, the output normally open contact is disconnected and the red light is on;
