Methane Detector has one measurement ranges to provide measurement in the range of 0-100%CH4 and two outputs (UW) to control equipment switching off power supply when the preset alarm thresholds have been exceeded. Optionally, it may also be equipped with ambient temperature sensor. Its autonomous supply system (battery) supplies the methane detector when the feeder line is switched off. The communication with the methane detector is carried out by means of digital transmission through the feeder-measurement line of the central station and through the type KR-2 calibrator. The calibrator communicates with the methane detector through a radio link.
Methane Detector CSM-1 version R is a device in category M1 and, therefore, may be used in all underground mines with methane or coal dust explosion hazard.
