QB2000N digital stationary gas monitor industrial with 4-20mA or RS485 output to control panel
QB2000N digital stationary gas monitor industrial with 4-20mA or RS485 output to control panel is
a fixed gas detector, with 4-20 mA or RS485 ModBus RTU output proportional to the gas leakage
concentration with original imported sensor.
It can be directly connected with DCS systems or Central unit. With relay output, once the concentration
exceed the preset alarm point(threshold) it will start the acoustic-optical alarm on the central unit and
drive the external equipment like exhaust fans.
It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological
medicine and water procession etc.
1. 4-20mA analog output for direct communication to DCS system, RS485 ModBus output for
central unit
2. Relay output for connecting external device
3. LCD display screen
4. Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
5. Password verification for repeat operation, avoid fault operations.
6. -40~+70℃ following compensation for accurate detecting.
7. Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive
exhaust device).
8. User-selectable alarm setpoint(s).
9. Note: QB2000N is with the digital display screen but QB2000T is without the digital display screen.
The visual and audible alarm is optional.
