Product Description

 

QB***0N/T is a Wall-mounted H2S hydrogen sulfide gas detector, with ***0 mA or RS**5 ModBus RTU output proportional to the ethylene gas leakage concentration with original imported electro-chemical sensor. It monitors ethylene gas leakage by natural diffusion. It is flexible, durable, accuracy, stable and etc. and it can be directly connected with DCS systems or Central unit. With relay output, once the ethylene gas 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.

 

Characteristics:

  • ***0mA analog output(3+ channel) for direct communication to DCS system, RS**5 ModBus output for central unit
  • Relay output for connecting external device
  • LCD display screen(LED display screen optional)
  • 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.
  •  **0~**0°C 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).

Note: QB***0N is with the digital display screen but QB***0T is without the digital display screen. The visual and audible alarm is optional.
