Liquid Level Sensor HBLT-A2
HBLT-A2 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-A2 is more compact.
HBLT-A2 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.
We recommend using HBLT-A3 instead of HBLT-A2 as the standard level sensor for ammonia. The A3 has been used in heat pumps for several years and provides better accuracy, especially at elevated temperatures. The only difference between the A2 and A3 is the mechanical part, which has a smaller pipe diameter. The electronic unit is identical and can be used on both the A2 and A3. All you need to do is change the settings.
- Advanced setting for controlling modulating valve
- 5m M12 cable included
- Easy configuration of the sensor
- The HBLT-A2 is a perfect solution under turbulent conditions like marine applications
- Split design which makes it possible to make easy installation and diagnostics
