Product catalog summary
Introduction
The V-Tork is a versatile point level switch designed for detecting liquid levels in various mediums, including water, oil, thick fluids, and corrosive substances. It is unaffected by the chemical or physical properties of the mediums and can be installed at any angle. The device operates up to 176ºF (80ºC) and 725 PSI (50 Bar), with models available in 316 stainless steel and PTFE coatings for sanitary applications.
Technology
The V-Tork uses a vibrating tuning fork principle with piezo-electric crystals. The frequency change when submerged is detected and converted into a switching output, providing accurate level detection.
Models Overview
  • VTK-DC: Compact switch for liquids and fine solids, ideal for PLC connections. Features a central LED for status indication, operates on 20-60VDC, and offers PNP transistor output.
  • VTK-R: Similar to VTK-DC but supports both AC and DC voltage. It includes a relay output and time delay adjustment.
  • MVTK-DC: Mini version with DC supply and transistor output, suitable for space-constrained applications. It is NEMA 6 (IP 67) rated for wet environments.
  • MVTK-AC: AC version of the Mini V-Tork with direct load switching output, requiring an external relay for operation.
Specifications
  • All models are designed for liquids with a maximum viscosity of 10,000 cSt.
  • Operating temperature ranges from 14 to 176ºF (-10 to 80ºC) for VTK models and up to 248ºF (120ºC) for MVTK models.
  • Pressure tolerance is up to 725 PSI (50 Bar).
  • Enclosures are made from glass-filled nylon, with wetted parts in 316 stainless steel.
  • Process connections include BSP or NPT threads, sanitary, or flanged options.
Features
  • Unaffected by variations in product density, conductivity, or dielectric constant.
  • Resistant to foam, tank agitation, or vibration.
  • Available with various process connections and coatings for aggressive mediums.
  • Relay and transistor outputs are available, with polished forks tested as needed.

Sitron's Line Of Vibrating Tuning Forks-1

Һ F (80 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 3/4ڔ up to 1 BSP or NPT process connection and insertion length L= 3 1/8Ԕ (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 > 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 crystal, and then provides an accurate output signal). >

Sitron's Line Of Vibrating Tuning Forks-4

The MVTK-DC (Mini V-Tork) is the most compact version of the vibrating point level switches that is also designed to detect the level of several types of liquids and some fine solids. The Mini V-Tork DC is available with a DC voltage supply and a transistor output. The electronics are integrated within the 316 S.S. body to best suit any space constraint issues relating to the application. A visual indication is given that shows the working status of the unit. The MVTK-DC can be made with a great variety of process connections, such as threaded, sanitary or flange and can be PTFE coated when necessary...
