The system is consists of hydrocarbon gas detection transmitter, oxygen sensor (optional) and Alarm panel. During operation of the system, the transmitter monitor hydrocarbon gas concentration and Transfer the concentration into corresponding current signal by DC4-20mA. At the same time, send the Current signal to PC Controller with RDYB Alarm Meter for displaying the concentration in real time. While the gas concentration is higher than the pre-alarm value or limit alarm value, corresponding the Audio-visual alarm is working in controller unit and indicate the point that emits alarm signal.
Voltage: Main AC220V／AC 110V Signal output：RS485 Back up DC24V Alarm state: 30%LEL (main alarm) 10%LEL (pre-alarm, adjustable) Failure alarm Sample object: Combustible gas in air; Measuring range:0～100%LEL,1～100%V/V Alarm type: audio-visual alarm
