Introduction

The V-Tork is a point level switch that is designed to detect low or high levels of liquids, as well as some types of fine granular solids.
Sitron's V-Tork is based on the vibrating tuning fork principle, using piezo-electric crystals. The switch vibrates at a resonant frequency. When the tuning fork is submerged in the product, the frequency changes. This change is detected by the integrated oscillator and converted into a switching output.
All models are made with 316 Stainless Steel and are available with Teflon coatings or hygienic fittings for sanitary applications. The V-Tork can operate in temperatures up to 176ºF and have a maximum working pressure of 725 PSI.

Do not hold V-Tork by the forks Correct way
of handling
Do not alter or bend the shape of the forks
Installation
7
The “S” logo is used as reference for the correct position of the forks when installing the V-Tork
Do not turn or handle by the housing
Seal the threadwith teflon tapebefore screwing
The V-Tork can be installed at any angle of the pipe or vessel to detect the presence of liquids.
Use the correct tool to screw the V-Torkby the hexagon part
