Product Description

QB2000N Fixed LPG Gas Detector 24vdc with 4-20mA  or RS485 output to control panel

Fixed LPG gas detector product description

 

QB2000N is Industrial grade LCD/LED gas leack detector, with 4-20 mA or RS485 ModBus RTU output proportional to the gas leakage concentration with original imported electro-chemical sensor. It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.

The online gas detector monitors gas leakage by natural diffusion.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.
