3.2 Principle of operation

The VEGACAL 63 sensor can be used universally for level measurement in conductive and non-conductive liquids.

The rod probe is fully insulated and the proven mechanical construction offers high functional safety.

Probe, measured product and vessel wall form an electrical capacitor.

The capacitance is influenced by three main factors.
