    Gas detector supplier, fixed gas detector and gas detection control unit, gas control panel


    Model CRGD-M2 is a new type gas control unit which can combine with our many series gas detectors to make up an intelligent industrial gas detection system, to monitor the gas concentration in industrial places.

     gas control unit gas detection system

    If the gas or vapor entered the gas sensor, the gas detector will send current signal to gas control unit. The gas control unit will display corresponding gas concentration value after data processing. If measured gas concentration exceeds preset alarm limit level, gas control unit will give audible-visual alarm signals and relay output to drive or control other equipment, such as valves, exhausters, alarm lights, spraying system, etc. This complete gas detection system will effectively prevent accident during industrial production.

    This gas detection control unit used big LCD display screen and high-grade keyboard for operation with Chinese and English menu. It is widely accepted because of the clear display and simple operation. The unique jamming resistance of software provides the function of self-checking for software fault, makes it be easy for maintenance.



    1) Chinese menu and English menu can be operated by different users.

    2) Used internal microprocessor with rich software function of signal collection from detectors, real-time data calculation, fault self-testing, power management, alarm display, alarm relay output, etc.

    3) It can receive 4-20mA standard analog signal and RS485 digital signal input at the same time, with big capacity and kinds of communication protocol.

    4) It can manage and monitor gas detectors for different gas types with different measurement ranges and concentration units.

    5) 4 relay output with optional NO or NC;

    6) Wall-mounting, simple operation.
