Brief introduction:
QB2000N fixed ethylene gas detector is stationary gas monitoring
device. It is sensitive to ethylene gas by use of natural
diffusion, not by pump.
With relay output, once the concentration exceeds 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.
Characteristics:
◆RS485 analog output for direct communication to central unit
◆Relay output for connecting external device
◆LED display screen
◆Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
◆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).
