Function and system design
Measuring principle A piezoelectric drive excites the tuning fork of Soliphant M FTM50, FTM51 and FTM52 to its resonance
frequency. If medium covers the tuning fork, the fork's vibrating amplitude changes (the vibration is damped).
Soliphant M's electronics compare the actual amplitude with a target value and indicates whether the tuning
fork is vibrating freely or whether it is covered by medium.
