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).
