Instruction manual
HB switches with large electronic unit
Covers: HBSC2-SSR, HBSR-SSR, HBSO-SSR
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. The basic electronic unit exist in two
versions 24 V and 90-240 V, and it must match the mechanical part.
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.
