The operating principle of the level monitoring sensor is based on the capacitive principle. It utilizes the change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor triggers an oscillator, causing it to oscillate at a frequency of approximately 600 kHz. The signal generated by the oscillator is then processed by a microprocessor-based evaluation circuit.

The level monitoring sensors are designed for two different types of media. The first type is for electrically conductive liquid mediums with relative permittivity within a range of εr 35 to 85, such as water, coolant, and water/glycol mixture. The second type is for electrically non-conductive liquid mediums with relative permittivity within a range of εr 1.8 to 6, such as engine oil, fuels, and hydraulic oil.

The level monitoring sensors are available in different output versions. The positive switching version provides an output signal when the liquid level reaches a predetermined threshold. The negative switching version provides an output signal when the liquid level falls below a predetermined threshold. The analog output version provides a continuous output signal that corresponds to the liquid level. The proportional analog output version provides a continuous output signal that is proportional to the liquid level within a specified range.

SHR level monitoring sensors are widely used to monitor the filling levels of liquids in various industries. They are designed to detect when a filling level exceeds or falls below a limit, and are suitable for monitoring aqueous mediums like coolants, AdBlue®, fresh water, waste water, bilge water, and oil-based liquids like motor oils, hydraulic oils, fuels, and brake fluids.

Due to their rugged design, high IP protection classes, and a wide working temperature range from -40°C to +125°C (-40°F to +257°F), SHR monitoring sensors are primarily used in engines, agricultural machinery, construction equipment, hydraulic power-train control systems, and utility vehicles. They can replace pressure switches or temperature sensors as level monitoring elements and provide an advantage by indicating a critical condition far earlier.

Temperature sensors may not react in time because the medium being monitored is no longer present, and pressure switches may not indicate low oil until there is a total shortage of oil, which is too late to protect the engine. SHR level monitoring sensors, on the other hand, issue a warning when there is still enough medium present.

Compared to float-type switches, SHR level monitoring sensors have a compact design and are resistant to vibration, as they do not have mechanical moving parts that can be affected by dirt particles or other external influences. Furthermore, they do not send electrical current through the medium via an electrode, eliminating the risk of electrolysis.
