Sulfur dioxide sensor CSSD-1 is a stationary device, use to measure sulfur dioxide in explosion hazard areas in underground coal mines. Mainly it cooperates with telemetric central station CST-40(A)(C) in transmission data area. It may also cooperate with other centrals provided that the terminal of the feeder-measurement line is compatible. .
The sensor has one output (UW) used to control the switching energy device when the preset alarm thresholds have been exceeded.
Its autonomous power supply (battery) supplies the sensor system when the supply line is disconnected.The communication with the sensor is carried out by means of digital or frequency transmission through the feeder-measurement line of the central station and through the type KR-2 calibrator. The calibrator communicates with the sensor through a radio link.
.
The sensor is a device of M1 category and may thus be used in all underground mines with possible methane or coal dust explosion hazard.
