HBLC NH3 Level controller

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.

 

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.
