A tuning fork liquid level switch is one of the most universal, versatile and safest designs for liquid level detection, whether overfill, overspill, high-high level – perhaps it is for low-level, dry run, or anything in between. So, why is this technique so universal? Its because it uses vibration to sense liquid presence, regardless of the liquid properties or changes in its characteristics, which means it reliable.

Vibrating Fork Level switches utilize a piezoelectric-driven tuning fork that exhibits a large change in resonant frequency when immersed into a liquid or bulk solid process.

The Compact tuning fork level switch Series VSTJ is a point level switch for liquid level detection in storage tanks, tanks with agitators, and piping. It can be used as an alternative to float switches as well as in applications where build-up, turbulence, liquid flow and gas bubbles are present.
