Intrinsically Safe Temperature Sensor

Intrinsically Safe Temperature Sensor is suitable for environments in coal mines containing explosive gas mixtures such as methane and coal dust. It is used in conjunction with the main unit of a comprehensive protection device for coal mine belt conveyors or a main unit of an automatic water-spraying dust reduction device for mines, connecting to an intrinsically safe system signal device. It monitors and protects the temperature of critical components such as the high-speed shaft of a reducer, the housing of an electric motor, and the bearing seat of a drive drum in underground coal mine belt conveyors. It can also be used in non-explosive environments above ground.
