Methane Detector CSM-3m is a stationary device for measuring methane content in explosion hazard areas in
underground coal mines. Mainly it cooperates with telemetric central station CST-40(A)(C) in transmission data area.
Methane Detector CSM-3m
Product Description
Product description
CSM-3m is equipped with infrared measurement chamber providing measurement in the range of 0-100% CH4 and one or two (UW) outputs to control equipment switching off power supply when the preset alarm thresholds have been exceeded as well as two two-stage inputs to control the status of contacts and lines of connected devices. Its autonomous power supply (battery) supplies the methane sensor system when the supply line is disconnected.
The communication with the methane detector is carried out by means of digital transmission through the feedermeasurement line of the central station and through the type KR-2 calibrator.
The sensor has LCD displays, that shows the current methane concentration, the state of inputs and outputs, and signals when the alert thresholds are
exceeded.
