HBLT-A3 HB Products NH3 Refrigerant Level Sensors for Heat Pump Version

HBLT-A3 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, HBLT-A2 and the first version HBLT-A1 is the mechanical design. HBLT-A3 is more compact making it stabile at higher temperatures.

HBLT-A3 is an intelligent sensor with a built-in microprocessor and it has the same digital display as the HBLT-A2. It emits a 4-20 mA signal, which is proportional to the sensor's preset range of measurement. Apart from the 4-20 mA signal the sensor also has a built-in controller. The controller can be configured 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 valve.

Available as 2-wire sensor with ATEX / IECEx certificate (This version is without LED display)

Product Features:

• Advanced setting for controlling modulating valve
• 5m M12 cable included
• Easy configuration of the sensor
• The HBLT-A3 is a perfect solution under turbulent conditions like marine applications
• Split design which makes it possible to make easy installation and diagnostics
