Product Description

GQQ5 Smoke transducer Explosion proof Coal mining Belt Conveyor smoke Sensor

Product Description

The GQQ5 type smoke sensor (hereinafter referred to as the sensor) is applicable to the environment of the underground coal mine which contains the explosive gas (ch4), as well as the work place such as the open-pit coal mine, the coal preparation plant and the like, and is used as the detection of the smoke protection signal of the protection device of the mine belt conveyor
 

Product Parameters

Ambient temperature:0ºC~+40ºC;


Average relative humidity:No greater than 95%(+25ºC)


Atmospheric pressure:80kPa~106kPa


No significant vibration and impact


There is a dangerous environment such as gas, coal dust and so on in the coal 
mine, but it does not destroy the insulating corrosive gas.


Wind speed:0~8m/s


Operating voltage:DC12±0.5V
Intrinsically safe operating current:≤150mA
Outline dimension:Φ130×160mm


Weight:4KG
Action condition:When smoke concentration 5%obs/m
Explosion-proof mark:Exd ib I Mb
Output signal:In smoke-free state, the contact is disconnected and the leakage resistance is not less than100kΩ
When there is a smoke state, the contact is closed and the voltage drop is not greater than 0 .5V(Infill current 2mA)
 

 

Smoke detection: smoke caused by skidding failure or other causes of belt conveyor can be detected

Signal output: when the sensor acts, the fault signal is output to the control host

Light signal prompt: when the sensor is in operation, the high-brightness red light-emitting diode light of the sensor flashes on and indicates the status of the sensor
 

When the smoke concentration in the monitored environment≤5%obs/m, the sensor output is a regular open point. When smoke concentration>5%obs/m, the output voltage of the smoke probe becomes higher, the internal comparator of the sensor is turned over, and the closed point signal is output.
