Fixed LCD HCL gas detector transmitter 4-20mA

Description

                       Fixed ***0mA  LCD HCL gas detector transmitter 

 

QB***0N/T-HCL  online LCD HCL gas detector transmitter ***0mA  is a fixed online gas detecting transmitter, with ***0 mA or RS**5 ModBus RTU output proportional to the gas leakage concentration with original imported electro-chemical sensor.  The online LCD HCL gas detector transmitter ***0mA monitors 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 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. The  online LCD HCL gas detector transmitter ***0mA 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.
