Tuning Fork

Measurement principle

A tuning fork shaped sensor is excited to its resonant frequency. The device works by piezoelectric effect. The oscillation frequency changes when the fork comes into contact with the product. The change is analyzed and translated into a switching signal.

ADVANTAGE

Applicable measurement for liquids in general

Ready to use, no calibration necessary

Adjustable sensitivity, operates even with foam or effervescent liquids

Operating temperatures from -60 ° C to + 280 ° C (-76 to +540 ° F)

Operating pressures from -1 to 100bar (-14.5 to 1,450 psi)
