Sitron’s V- TorkVibrating Tuning Fork for Level detection

Models:

Introduction

º F (80 º C) and has a maximum working pressure of 725 PSI (50Bar). All models are made with 316 S.S. and are available with PTFE coatings or in hygienic versions for sanitary applications. Standard probes are available with 3/4” up to 1” BSP or NPT process connection and insertion length L= 3 1/8” (L= 80mm). The V-Tork is a point level switch that is designed to detect low or high level of liquids (such as water and oil), thick and turbulent fluids, as well as corrosive mediums and pastes (depending on viscosity). Due to its simple and rugged controlled system, the V-Tork is virtually unaffected by any chemical or physical properties of the mediums and can be installed at any angle of the pipe or tank. It is ideal for multiple-purpose processing where the probes must be compatible with a variety of process materials and process conditions. The V- Tork does not require recalibration between batches and can also be cleaned in place. The V-Tork can operate in temperatures up to 176

Technology

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 will change. This change is detected by the integrated oscillator and converted into a switching output. (The integrated electronics evaluates the level signals, according to the oscillation of the sensor's industrial crystal, and then provides an accurate output signal).
