Product Introduction

The HI-TOUCH explosion-proof tuning fork level switch HF series from the United States is a universal level switch. The tuning fork is excited by a piezoelectric crystal to produce vibration. When the tuning fork is immersed in liquid or solid, the vibration frequency changes, which are detected by electronic circuits and output as a switch value. The tuning fork level switch is not affected by the electrical parameters of the medium, as well as factors such as turbulence, agitation, bubbles, and vibration. It has no moving parts and therefore does not require maintenance or adjustment. It is an ideal choice for level switches under complex working conditions.
