Intelligent Gas Transmitter Detector

We are offering intelligent gas transmitter detector.
•qb2000n is a microprocessor based intelligent sensor transmitter. Which provides 4-20 ma output and modbus rtu output proportional to the gas concentration and has led(lcd optional) digital display real-time gas concentration. Its rs485 digital signal is for communication. It easy to operate, reliable and has full functions, making it a leader in the nation. It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
characteristics:
◆sensor types: electrochemical sensor; catalytic sensor; infra-red (ir), photo ionization detection.
◆4-20ma analog output(3+ channel) for direct communication to dcs system and rs485 modbus output
◆sensor module design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
◆ led display(lcd optional)
◆password verification for repeat operation, avoid fault operations.
◆ -40～+70℃ following compensation for accurate detecting.
◆ second grade visual alarms on-site and relay(connected with audible/visual alarms or drive exhaust device).
◆user-selectable alarm setpoint(s).
