A unique, but easily adaptable solution for automatic defrosting of evaporators. The sensor measures the thickness of ice built up between the fins and emits a 4-20mA or digital ON/OFF signal to the control systems. A temperature sensor (PT1000) is located at the fins, near the bottom part of the evaporator.
It senses when defrost is completed and stops the sequence.

A simple solution for energy-optimal automatic defrosting of evaporators. It results in energy saving, gain more freezing capacity with optimal defrost periods. The sensor measures the thickness of ice building up between the fins and sends a 4-20mA or digital ON/OFF signal to the control systems.

Temperature sensor in two variants, PT100 and PT1000. Designed for the refrigeration industry where servicing of the electronics can be carried out without emptying the system of refrigerant. The sensor is delivered with a 60 & 90 mm sensor element length and a 6 mm sensor diameter. Sensor well is included with the sensor.

The sensor is used for analogue position measurements of industrial refrigeration compressors in connection with capacity control.
The sensor is available in both a standard and an EX edition. It has a measurement angle of 300°, which can be rotated infinitely.
The sensor sends an analogue 4-20 mA signal corresponding to a rotating movement.

Sensor used to measure the pH value of brine in case of an ammonia leak in a heat exchanger. Can be used with HBPH-C1 controller, used to calibrate and set up the alarm limit for the HBPH-MK2-LT sensor.

Gas leakage measurement in a range of 0-1000 ppm. 3 built-in digital alarm output and 1 analog 4-20 mA output. The sensor can be set up using a PC with the HB Configuration Tool.The sensor element has a lifetime of 2 years and can easily be replaced. On the front, you can find 4 integrated LEDs for displayof the supply (green) as well as 3 alarm levels (red, orange, and yellow). The sensor is factory calibrated and verification during the lifetime can be done with high gas concentrations. The sensor is optimized for use in areas where cleaning solvent are used.Built-in heating element ensures low ambient temperatures down to -30 ° C.

Capacitive liquid level transmitters used to measure liquid levels in refrigerant vessels. 4 to 20 mA output signal. Configurable via a PC with 3 parameters to set up the sensor. Digital display with built-in configurable controller for control of a modulating motorised valve.

The case story below features the new HBLT-A3 sensor. It demonstrates how the sensor delivers reliable and precise performance across the required temperature range in ammonia containers.

HBPH-C1 is a display designed for connection with the HBPH sensor. Available for either panel or cabinet installation, indoors or outdoors. 110/240VAC.

Vapor Quality Sensors using innovative technology which makes it possible to measure the mix between gas and liquid in a refrigerant from 0% gas to 100 % gas.
The sensor offers very precise measurements and provides instant read-outs of the gas quality and also functions as a controller, enabling the direct control of a modulating motor valve. All vapor quality sensors are suitable for controlling both DX, semi flooded and flooded operation.
Available in either inline, strainer housing or angle configurations.

Capacitive sensor for level measurement of refrigerant in industrial refrigeration systems. 4-20 mA output signal. HBLT-wire can be adjusted in length to the current application.The sensor element consists of a 2mm steel wire as well as a Teflon tube. Both parts are provided with a length of 4 m and can be shortened with diagonal cutters or other pliers.
