CO2 Level Controller
CO2 Switch
HBLC is an intelligent sensor with a built-in microprocessor. It is designed to control refrigerant levels in both low pressure and high pressure systems. It emits a 4-20 mA signal, which is proportional to the sensor's set range of measurement.

Apart from the 4-20 mA signal, the sensor also has a built-in controller.

The controller can be set-up with all the parameters necessary for controlling a modulating motor valve or stepper motor.

The sensor can be delivered with a cable for direct supply to and control of motor valve or stepper motor valve.
  • Product features

    • Stand alone solution together with modulating valve. Flexible and cost effective alternative to float switches
    • Simple installation and configurering with PC. The regulation loop, timer and alarm are all programmable
    • LED indication of power supply, alarm and regualtion status. Further an alarm status can be given to central panel.
    • Split design which make it possible to make easy installation and diagnostic. The electronic part can be easily disconnected by 2 screws.
    • The sensor can control modulating valve, pilot valve or stepper motor valve.
