Product Details

QB2000N combustible gas detector is a microprocessor based intelligent sensor transmitter. Whichprovides 4-20 mA output andModBus RTU outputproportional to combustible gas concentrationand 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:catalytic combustion sensor.

◆4-20mA analog output(3+ channel) for direct communication to DCS system andRS485ModBusoutput

◆Sensormodule 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 compensationfor accurate detecting.

◆Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).

◆User-selectable alarm setpoint(s).

Technical Parameters:

◆Range：refer to the chart following.
◆Working voltage：24VDC±15%
◆Signal output：4～20mA linear current output；or RS485 ModBus output
