HB Products Level Sensor
All sensors consist of a mechanical and an electrical part. The mechanical part has no moving elements, and it can have different shapes and length. The electrical part is either pre-calibrated or easy to calibrate versions. All the sensors can be supplied in a special version for direct valve control of a liquid valve. All sensors must be supplied with 24 V AC/DC.
Most of the electronic units are suitable for wet and low ambient temperatures due to a built-in heater which will protect it against condensation.
The mechanical parts are manufactured up to 3000 mm length in a rigid rod version and for longer applications we have flexible wire version which can be used in standpipes from 250 mm to 6 m length. Most of the sensors has a ¾” or ½” connection with different thread types and normally rated for 100 or 150 bar pressure.
Most of the sensors can be equipped with a special 2 wire electronic unit suited for hazardous environments and comply with the IECEx specifications.
HB Products Liquid Level Sensor – Technical data for Type: HBLT-A3
HBLT-A3 capacitive liquid level transmitters are used to measure liquid levels in refrigerant vessels, Heat Pumps and other industrial applications. 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).
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 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, stepper valve or a PWM valve.
Available as 2-wire sensor with ATEX / IECEx certificate (This version is without LED display)
