Level Sensor - FlexCategory: HBLT-Flex - HFC / HFO / CO2

Functional description:

HBLT-flex is a capacitive sensor for level measurement of HFC/HFO/CO2 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-flex 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-flex 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.

Flexible sensor wire, which is adjustable to a length of 200 to 800 mm.

Simple calibration for the specified length.Compact design that

minimises shipment costs.

Measures HFC refrigerants (R22, R134A, R404A, R410A, R507, R717

& R718).

5 m cable included.

Can be used for marine applica-tions, since measurement is not

affected by contact with the metal surface of the overflow pipe.

Alarm output can be set in a range from 10% to 100%.

3 digits display showing level in percentage.

HFC Refrigerant Level Sensor (Rod)Category: HBLC-HFC

Functional description:

HBLC-HFC is an intelligent sensor with a built-in microprocessor. It is designed for continuous level measurement of liquid HFC refrigerant in refrigeration systems.

HBLC-HFC is designed for the measurement of HFC refrigerant level in chillers, evaporators and condensers. The sensor is pre-configured to R134, but can be configured for other HFC types.

The sensor emits a 4-20mA analog signal, which is proportional to the liquid level.The construction of the sensor makes it suitable for systems with pressure of up to 150 bar.

Application Examples

• Available as 2-wire sensor • Now with ATEX / IECEx certificate (This version is without LED display)
