Industrial 4-20mA Or RS485 Gas Sensor For NH3
QB2000N is an Industrial 4-20mA Or RS485 Gas Sensor For NH3 with original imported electro-chemical sensor. It monitors gas leakage by natural diffusion. Once the gas concentration exceed the preset alarm point, it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans.
- 4-20 mA or RS485 ModBus RTU output proportional to the gas leakage concentration.
- Flexible, durable, accuracy, stable etc.
- Can be directly connected with DCS systems or Central unit.
- With relay output, It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
Characteristics of Industrial 4-20mA Or RS485 Gas Sensor For NH3 :
• 4-20mA analog output for direct communication to DCS system, RS485 ModBus outputfor central unit
• Relay output for connecting external device
• LCD display screen (LED display screen optional)
• Sensormodule (block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
• Password verification for repeat operation, avoid fault operations.
• -40~+70°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: QB2000N is with the digital display screen but QB2000T is without the digital display screen. The visual and audible alarm is optional.
