Type coal mine damper opening and closing status sensor
1. Overview
The coal mine damper opening and closing status sensor is a magnetically driven position switch sensor. This product can be used in coal mines where there is a risk of methane and coal dust explosions. It is installed on dampers at all levels in underground tunnels to detect the opening and closing status of the dampers and provide damper status information for ventilation management. It can be used with various mine monitoring and control systems, and its power switch contact signal or current signal can be directly provided to the mine monitoring and control system for collection and processing.
