NH3 Refrigerant Level Sensor for Heat Pump Applications

Technical data: HBLT-A3

HBLT-A3 with external temperature compensation for heat pump applications.

HBLT-A3 capacitive liquid level transmitters are used to measure liquid levels in refrigerant vessels. The sensor transmits a current signal from 4 to 20 mA (4 mA when the transmitter does not register liquid - and 20 mA when the entire transmitter is surrounded by liquid).
The difference between the new HBLT-A3 and the first version HBLT-A1 is the electronic head. We have used the electronic head from our HBLC sensor, which gives more opportunities in the PC tool for configuration with 3 parameters to set up the sensor. 

HBLT-A3 has the same digital display as the HBLT-A2 which differs from of the bar graph known from HBLT-A1 and HBLT-A3 is an intelligent sensor with a built-in microprocessor. 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. The sensor can be delivered with a cable for direct supply to and control of motor valves.
