Type air duct air volume switch
Type air duct air volume switch is a new device for mine air duct ventilation safety monitoring and is an intrinsically safe device. This switch is mainly used for safety monitoring of air ducts made of flexible materials such as canvas or rubber underground in coal mines. It is installed on the air duct, meters away from the air outlet. The switch is a matching device for the monitoring system substation and similar monitoring equipment, and is used to remotely measure the working status of the air duct.
