HBLT-A2 Parker - Refrigerating Specialties NH3 Liquid Level, Transmitter Probes

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-A2 and the 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-A2 has a digital display instead of the bar graph known from HBLT-A1 and HBLT-A2 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.
HBLT-A2 provides new possibilities but has the same price as HBLT-A1.

Features:

• Digital display
• Controller built inside
• Advanced setting for controlling modulating valve
• 3 parameters to set up the sensor
• Easy diagnostics
• 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. The electronic part can be easily disconnected by loosening the threaded nut/union nut
• Proven and reliable design with process signal output of 4-20 mA
• Designed for the industrial refrigeration industry - max pressure up to 100 bar & high protection class
