GQQ0.1 MINE Smoke sensor
Feature
4.mine intrinsically safe
2.volume small light weight
3.mine explosion proof type
Description
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 convenient and 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
