Manual for wire level sensors delivered after October 15th 2021*
Covers: HBLT & HBSLT
Wire sensor suited for liquids like NH3, and HFC/HFO refrigerants -not suited for water.
*Changes has been made to the sensor shipped from October
15th. The manufacturing date can be found on the silver label
on the electronic unit and it is the last 4 numbers in the V num-
ber in the format DDMMYY, The sensors can also be recog-
nized by the SW numbers:
73 or higher for RF3
32 or higher for RF4
The numbers are found at the top of the tool window when the
sensor is connected
Introduction
Wire and Flex are intelligent liquid level sensors which can be installed in a vessel or in a standpipe. For the Wire sensor the
sensor element is a stainless steel wire insulated with PTFE and for the Flex sensor the element is a stainless steel wire
mounted with steel tube elements to increase the sensitivity. Both sensors can to be mounted directly in a stand pipe. If they
need to be installed in a vessel they need an inner pipe. Both sensors measure between the wire/tube elements and the sur-
rounding pipe.
The sensor can be installed in refrigeration systems and similar demanding applications with high pressures and aggressive
fluids. The sensor emits a 4-20mA analog signal, which is proportional to the liquid level.
The sensors comes in different versions with or without a cable for direct valve control. All versions emits a 4-20mA analog
signal, which is proportional or disproportional to the liquid level, via the M12 plug. The sensors are available in special ver-
sions which contains a controller able to control a valve directly, without using a PLC.
