Product Description

 {C}QB***0FCis a fixedcombustible gasdetecting transmitter, with***0mAor RS**5ModBus RTU outputproportional to thecombustible gas(LPG or methane)leakage concentration with original imported catalytic combustion sensor. It monitorscombustible 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 thecombustible gasconcentration 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 car parks and water procession etc. 

Characteristics:

◆***0mA analog output for direct communication to DCS system, RS**5ModBus output for central unit

◆Relay output for connecting external device

◆Password verification for repeat operation, avoid fault operations.

◆ **0～**0℃ 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).
