GQQ0.1Smoke sensor

GQQ0.1Smoke sensor, smoke sensor,GQQSmoke sensor

GQQ0.1For mine intrinsically safe type smoke sensor, suitable for the coal mine gas, coal dust explosive gas environment, with belt so keep monitor (also can be used for other electronic matching), because of the friction heating used in coal mine belt conveyor belt detect smoke protection or other reasons.

Using the environment conditions

The altitude does not exceed+2000m, no less than-1000m

Ambient temperature:- 5~ +40

Environmental relative humidity is not more than95%25).

With the explosive gas and coal dust in mine.

Without enough corroded metal shell and electrical insulating gas.

Can prevent sewage and other harmful liquid into place.

Without a strong vibration and shock environment
