Suitable for control of liquids such as oils, water, paints and transparent inks, sauces, milk, liquids containing carbon dioxide, oil foaming. RSL100 is designed as a shortcut to 2 / 3 wires and for universal use in tanks and pipes.

The level switch for liquids works on the principle of the tuning fork in the air at a resonance frequency. A piezoelectric crystal is used for the excitation of the oscillation and to control the frequency. When the tuning fork is immersed in liquid, the frequency changes: this change is detected electronically and changes the exit signal. The device operates as a two-wire switch in series with the load. The simple electronic switch is operated by the liquid. The probe can also be connected to a PLC through a third terminal. The output signal can be controlled by approaching a magnet at the PVDF.
