NIVOSWITCH series standard tuning fork type liquid level switch

Product Introduction

The working principle of a tuning fork type liquid level switch is to vibrate the tuning fork at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork comes into contact with the measured medium, its frequency and amplitude will change, and these changes will be detected, processed, and converted into a switch signal by an intelligent circuit.

The NIVELCO tuning fork type liquid level switch NIVOSWITCH series standard model is almost suitable for all liquid media, such as liquids with explosive and non explosive hazards, corrosive liquids (acids, bases), high viscosity liquids, etc; It is not affected by foam, vortex and gas. It is also suitable for measuring medium density solid powders or particles that can flow freely.
