Gas Detection Controllers & Central Monitoring Systems
Combustible Gas Alarm Controller Connected with Point-type Combustible Gas Detector
Combustible gas alarm controller is used in conjunction with explosion-proof point-type combustible gas detectors. The detector converts the on-site combustible gas concentration into digital signals and transmits them to the controller via the 485 bus. The controller can display the current number of channels, gas concentration of each channel, as well as alarm and equipment fault statuses. When the gas concentration reaches the preset alarm value, the detector will automatically trigger an audible and visual alarm and output a signal. Meanwhile, the controller will also activate audible and visual alarms and send out control signals to prompt operators to take timely measures, so as to prevent various potential safety accidents.
