I agree with the Terms and Conditions

Standard length vibrating probe level sensor

Unique single-rod probe design with a sword-shaped blade to prevent buildup and bridging.

Looking for a point level sensor for light & fluffy or low dielectric materials?

The VR-21 piezoelectric vibration point level switch works even in carbon black, plastics, or fly ash

How it works:

The blade vibrates until the vibration is dampened when material covers it and triggers a relay indicating a covered condition.
