HBLT-wire

HBLT-Wire - Refrigerant wire sensor

HBLT-wire is a capacitive sensor for level measurement of NH3 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-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.

HBLT-wire 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 Applications Specifications Ordering code
  • Flexible sensor wire, which is adjustable to a length of 300 to 4000 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.
  • Alarm output can be set in a range from 10% to 100%.
  • The possibility for direct regulation of modulating valves, pilot valves, or step motor valves.
  • Compact design that minimises shipment costs.
  • Can be used for marine applications, since measurement is not affected by contact with the metal surface of the overflow pipe.
  • Measures NH3 & HFC refrigerants (R22, R134A, R404A, R410A, R507, R717 & R718).

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