The natural frequency of piezoelectric crystal and tuning fork is used to drive and feed back the tuning fork rod, so that the tuning fork rod can produce resonance.
When the material level contacts the tunng fork rod, the frequency signal feed back by the turning fork rod will be converted into a contact signal. When the circuit detects that the frequency of the signal decreases.
1. It can be used in safety Systems with SIL2/SIL3 functional safety requirements.
2. It can be used in aseptic applications in the life science industry.
3. No need to adjust: quick and economical start-up.
4. No mechanical moving parts: maintenance-free, no wear, long service life.
5. Functional safety: fork body damage monitoring. ô.One-piece stainless steel housing (optional): can reach IP68 protection level.
