GKD36V Mining explosion-proof and intrinsic safety feeding state sensorDetailed product description：

GKD36V mining explosion-proof and intrinsic safety feeding state sensor (hereinafter referred to as the sensor) is a type of mining explosion-proof and intrinsic safety protection equipment. Sensors can be used in conjunction with other related devices, with a power supply function that can monitor whether the disconnected device continues to work after a power outage.

Environmental Requirements for GKD36V Mining Explosion proof and Intrinsic Safety Feed State Sensor
The environmental conditions required for equipment use are as follows:
a) Environmental temperature: 0 ℃~40 ℃;
b) Humidity: ≤ 95%;
c) Atmospheric pressure: 80kPa~110kPa;
d) In Class I situations where there is a methane explosive gas mixture underground in coal mines, but there is no corrosive gas that damages insulation;
e) In situations where there is no significant vibration or impact.
