HFC Refrigerant Level Sensor (Flex)

Technical data: HBLT-Flex

HBLT-flex is a capacitive sensor for level measurement of HFC/HFO/CO2 refrigerant in industrial refrigeration systems. The sensor has an output signal of 4-20 mA, which is proportional with 0 and 100%. Its output signal is 4 mA for an empty container and 20 mA for a full container. HBLT-flex 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. HBLT-flex can be used in connection with the HBLT-C1 controller for controlling pumps, etc., or it can be configured to directly control a valve without the need for another controller.

Product features

Flexible sensor wire, which is adjustable to a length of 0 to 1400 mm with a jump of 50 mm.
Sturdy and reliable design with a standard 4-20 mA output signal.
Designed for the refrigeration industry – max. pressure up to 100 bar.
Split design which makes the sensor easy to install and service. The electronic part can easily be separated from the mechanical part by loosening the threaded union.
Simple calibration for the specified length.
Can be used in compact systems where installation height is low.  
Can be used for marine applications, since measurement is not affected by contact with the metal surface of the overflow pipe.

The sensor can be programmed to either emit a linear signal, which is identical to the tank level, or to regulate a valve for the purpose of obtaining the same level in the tank (float valve).
