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.

    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.

    If changes are made to type-approved equipment, this type approval becomes void. The product's input and output, as well as its accessories, may only be connected as shown in this guide. HB Products assumes no responsibility for damages re- sulting from not adhering to the above.
  • Page 3 Application Examples HBLC and HBSLC HBLC consist of a PTFE covered rod and requires a electrical connection to the overflow pipe or to the pipe segment where it is installed. The sensor is more sensitive to turbulent conditions but with a high filter time it is able to control the level even in turbulent conditions.
  • Page 4: Application Examples

    Application Examples HBLT and HBSLT are designed for level measurement of liquids and is typically used in chillers, pump separators, coolers and condensers. The sensors can be mounted in vessels , containers and standpipes without an external pipe.

    Setting up the sensor When the sensor is delivered with one of the predefined liquids it is pre-calibrated and need no further calibration. The sim- ple sensor can still be setup using a simple tool where filter time and calibration can be made. The advanced sensors has mul- tiple parameters.
