HB switches with circular electronic unit
Covers: HBSC, HBSR, HBSR-HFC, HBSO-LT, HBSO1, HBSO2, HBOR, HBSO1-MT & HBSO2-MT
Functionality
The switches are used for detecting liquid in gas or air (HBOR detect oil in liquid ammonia). The mechanical elements have
different design because they are optimized to different liquids. The switches use the capacitive measuring principle and react to
the difference in dielectric constant between liquid and gas.
The switches have different calibration and parameter settings in the electronic unit, but unit is the same. The settings cannot
be changed by the user, and it must match the mechanical part. Switches delivered after September 2020 has a build in heater
which will be in operation below 5°C to keep the sensor dry
Standard switches available from HB-products
Switches from HB-products are suited for different fluids, different temperature ranges and supply voltages. There is a special
program for oil switches. The two tables show the recommended products.

- Page 2 Liquid switches What can happen if the switch is installed outside the recommended temperature range The HB-products web page has temperature specifications for the switches, and these will be different from the recommended temperature specifications. The switches will operate outside the recommended range but will not be optimal. For oil switches the switch point will change with temperature and this means there is a risk that the switch will not detect oil or detect without oil.

If changes are made to type-approved products, 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 resulting from not adhering to the above. -
Page 4: Led Indication
LED indication 4 x red LED´s indicate liquid/oil detection. 4 x green LED´s flashing indicate no detection, but sensor is active. 4 x red flashing LED´s indicate no connection to mechanical unit. Irrespective of the output function (NO/NC) LED´s are activated when liquid is detected. -
Page 5: Mounting The Electronic Unit
The sensor electronics are completely embedded and can therefore not be repaired. In case of faults with the sensor, it will typically only be necessary to replace the electronics. If you have a faulty product, please contact the HB Products dealers/distributors. Their complaints procedures must be followed before returning the sensor.
