Manual for rigid level sensors and controllers
Covers: HBLC, HBLT, HBSLC & HBSLT
For analog measurements of liquids like NH3, water, HFC/HFO refriger-
ants, CO2, Hydro carbons and alcohols.
Can be used in refrigeration systems and similar demanding systems.
Introduction
HBLC, HBLT , HBSLC and HBSLT are intelligent liquid level sensors which can be installed in a vessels or in a standpipes. The
sensors can be mounted directly in a stand pipe or in a vessel. The HBLC and HBSLC are sensor without an external pipe
which means they measure between the sensor element and the vessel or standpipe whereas the other types has an exter-
nal pipe and measures between the inner rod and the outer pipe. Installation and configuration is similar for the two product
types and they share the electronic heads.
The sensor can be installed in refrigeration systems and similar demanding applications with high pressures and aggressive
fluids.
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.
