About vibronic point level detection

Vibronic point level detection offers safe overfill prevention in liquids and bulk solids in every industry. The second line of defense guarantees the highest degree of safety and availability of the switches. Liquiphant stands for reliable switching unaffected by: changing media properties, turbulences, foam, vibrations or build-up. In silos containing fine-grained or powdery solids Soliphant is the perfect match. For more information click on the button below.

Vibronic devices perfectly fit for numerous liquid applications from simple operational point level detection (min. and max. control), certified leakage monitoring and overfill prevention through to protective equipment in plant parts subject so Safety Integrity Levels (SIL 2/3). For applications in powdery or lumpy bulk solids the vibronic devices can also be used in hazardous areas, typically in primaries, the chemical or the food industry.

Vibronic point level detection: Measuring Principle

For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. The drive works piezoelectrically. The oscillating frequency changes as the fork enters the medium. The change is analyzed and translated into a switching signal.

In solids a one-rod sensor is excited at its resonant frequency. The drive works piezoelectrically. The amplitude changes as the fork enters the medium. The change is also analyzed and translated into a switching signal.
