Manual for all flexible level sensors and wire sensors delivered be-
fore October 15th 2021
Covers: HBLT & HBSLT
Wire sensor suited for liquids like NH3, and HFC/HFO refrigerants
•
Flex sensor suited for liquids like CO2 and Hydro carbons
•
Can be used in refrigeration systems and similar demanding systems.
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.

Page 6: Installation Wire
Wire adjustment—Wire sensor The sensor is installed in the standpipe or directly in the tank. The sensor length is determined by standpipe length or tank height. Cut the insulated steel wire to desired length with a wire cutters or bolt cutter in the end where the weight is in- stalled. -
Page 7: Installation Flex
Installation instruction—Flex sensor The sensor can be shortened to fit the standpipe length or vessel height. The sensor consist of a 5 mm steel wire fitted with a stainless steel weight at the bottom, plastic spacers and aluminum pipes. The purpose of the plastic spacers is to keep the metal parts away from the pipe and the aluminum pipe increase the sensitivity of the sensor. -
Page 8: Connection Diagrams
How to connect the sensor Two different type of sensors • A pure sensor version with 4-20 mA output • A controller version with both cable for direct valve control and analog output All sensors can provide a signal for a PLC via the M12 connection. The M12 connection is also used for power supply. Some versions are able to control a valve directly. - Page 9 Connection diagram for sensors with control ca- Suited for • HBSLT/S and HBSLT–wire & Flex/S ble for all common stepper motor valves — here • HBSLC/S shown with Carel E2V +24V DC or AC - Common AI Remote set point 4-20 mA AO, 4-20 mA level Run in signal The sensor has a build in controller for a stepper valve.
