Mining smoke sensors

Monitoring in the coal mine machinery fault friction, heating cable, such as coal seam spontaneous combustion causes of fire accident

Can be installed in the coal mine belt conveyor machine machine beside easy to fever

For mine belt conveyor protection devices of the smoke protection signal detection

Performance feature

The installation of the sensor ,debugging and maintenance convenientand reliable

Sensor uses type gas sensitive sensor components, sensitive, reliable, and correct action

When measured smoke concentration is 0.1 mg/m3 or output low level signal to achieve smoke protection belt conveyor
