INTRODUCTION: |
|
|
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 176ºF (80ºC) 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). |

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 crystal, and then provides an accurate output
signal). |

VTK-DC - Power Supply: 20-60VDC - ( 3 Wires )
Output: PNP Transistor |
|
| |
|
The VTK-DC is a compact point level switch designed
to detect the level of several types of liquids and some
fine solids. It is the ideal solution for applications
that are connected directly to a PLC. A visual indication
is given by a central LED that shows the working status of
the unit.
The VTK-DC is made with 316 S.S. with a glass
filled nylon enclosure, it is available in a great variety
of process connections, such as threaded, sanitary or
flange and can be PTFE coated when necessary for
aggressive mediums.

VTK-R - Power Supply: 20-60VDC / 20-264VAC
Output: Relay ( SPDT ) |
The VTK-R is a compact point level switch designed
to detect the level of several types of liquids and some
fine solids. It provides AC and DC voltage supply to best
suit any application. A visual indication is given by a
central LED that shows the working status of the unit.
The VTK-R is made with 316 S.S. with a glass filled
nylon enclosure, it is available in a great variety of
process connections, such as threaded, sanitary or flange
and can be PTFE coated when necessary for aggressive
mediums.
Time delay adjustment for VTK-DC & VTK-R models
The VTK-DC and VTK-R models also provide a time delay
adjustment that enables the user to adjust 1,5,10 or 20
seconds as indicated by the drawing below.
( 1 ; 5 ; 10 ; 20 seconds )

MVTK-DC - Power Supply: 20-60VDC
Output: PNP Transistor |
|
| |
|
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 for
aggressive mediums.
All MVTK-DC are NEMA 6 (IP 67) protection class, enabling
the switch to be applied in damp, wet or submerged
applications.

MVTK-AC - Power Supply: 85-264 VAC
Output: Direct Load Switching |
|
| |
|
The MVTK-AC is the AC version of the Mini V-Tork,
available with an AC voltage supply direct load
switching output (2wire). It is also designed to
detect the level of several types of liquids and some
fine solids. The electronics are integrated within the
316 S.S. body to best suit any space constraint issues
relating to the applications. A visual indication is
given that shows the working status of the unit.
The MVTK-AC can be made with a great variety of
process connections, such as threaded, sanitary or
flange and can be PTFE coated when necessary for
aggressive mediums.The MVTK-AC is a 2 wire switch. It
is necessary to use an external relay (contactor) in
series with the power supply.
