Vibrating Level Switches

Vibrating level switches, also known as tuning fork level switches or vibrating fork level switches, offer a proven, low-maintenance method for detecting the presence or absence of material in tanks, vessels, and pipelines. Using the vibration frequency principle, these devices provide precise, repeatable switching signals for liquids and light bulk solids, unaffected by density, conductivity, or turbulence.

How Vibrating Level Switches Work

Vibrating level switches operate on the vibrating fork principle. A piezoelectric drive causes the fork to oscillate at its natural frequency. When the fork comes into contact with liquid or solid material, the frequency decreases. This change is detected by the electronics, which trigger a switch signal.

This simple, calibration-free technology ensures fast, accurate, and reliable level detection, even in media affected by foam, viscosity, or buildup.

Where Vibration Meets Reliability in Level Control

Vibrating level switches bring together the precision of vibration technology and the dependability required in modern process environments. The tuning-fork principle ensures that each switch responds instantly to contact with liquid or solid media regardless of foam, turbulence, or changes in density.
With no moving parts or calibration drift, these switches operate consistently even in harsh or hygienic systems. Their rugged construction, coupled with intelligent self-monitoring, guarantees stable operation and early fault detection.
From storage tanks to sanitary vessels, vibrating fork switches provide uncompromised reliability in level control, helping facilities maintain safe, efficient, and uninterrupted process performance.
