QB2000 gas alarm controlleris a multi-point monitoring of the latest design with simple operation and it combines with any gas detectors to form an industrial gas detection system. This system controller embeds micro processor as control unit, high-performing catalytic air-sensitive element, high-precision imported electrochemical sensor as detector which has high sensitivity and quick response. When the detected gas density in the air reaches or exceeds the preset value, the controller will give out audio-visual alarm immediately to remind you take safety precautions and alert the corresponding valve, exhauster and other equipment to avoid explosion, fire, toxic gases to protect the safety of life and treasures.
This system applies to metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmaceutical, sewage dealing and many other special industry and field that need proofing for fire, explosion, and toxic gas leakage.
Characteristics:
- high-performance sensor
- 128*64 dot matrix big screen liquid digital display
- With English Instruction Manual and pictures easy to operate
- various gas detector together to fix
- display the detected gas density in distance
- high sensitivity, and quick response
- Automatic compensation for temperature drift and time drift
- The up and low alarm points of each channels can be set separately
- 8 channel 4-20mA signals output
- RS485, RS232 communication port can upload data to computers
- 4 Relay output and the relay setting is programmable.
