Power plant usage Hydrogen gas alarm systems with 4-20mah signal output
Product Description
QB2000N is Industrial grade LCD/LED gas leack detector, with 4-20 mA or RS485 ModBus RTU outputproportional 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.
Features
- Changable Sensor mould
- Relay output for connecting external device
- LCD display screen(LED display screen optional)
- Password verification for repeat operation, avoid fault operations.
- Second grade visual alarms on-site and Relay(connected with audible/visual alarms or drive exhaust device).
- selectable alarm setpoint.
