HBLC-NH3-4-2 HB Products Liquid Level Control Sensor for NH3

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.

The sensor is delivered in a version without integrated cable (named HBLC) and a version with cable for direct control of valves (named HBSLC).

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 sensor can control modulating valve, pilot valve or stepper motor valve.
