RDQJ-1 Combustible Gas Detection System

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.
