Intrinsically Safe Infrared Temperature Sensor

Intrinsically Safe Infrared Temperature Sensor is designed for use in coal mine underground environments that contain explosive gas mixtures such as methane and coal dust. It can be integrated with the main control unit of the coal mine belt conveyor comprehensive protection device or the mine automatic water spray dust reduction device host. It connects to an intrinsically safe system signal device and is used to detect and protect against overheating in various components of underground coal mine belt conveyors such as the high-speed shaft of the reducer, the motor casing, and the bearing housing of the drive drum. It is also suitable for surface non-explosion-proof environments.
