IL - Monitor Technologies'
BINATROL® diaphragm switch is a durable and low-cost
solution for detection of product levels in dry material
units can be used to eliminate bin overflow, maintain a predetermined
material level, indicate plugging of chutes or conveyors
or provide any of a number of level control functions.
flush mount, non-intrusive BINATROL® units are ideally
used when vessel size or internal clearance is limited, or
where protrusion into a vessel is not acceptable. All installation
and servicing, including diaphragm replacement and sensitivity
adjustment, can be done from outside the vessel.

with various switch sensitivities, diaphragm materials and
IL - The PZP vibratory level
sensor is available in multiple configurations making it
the perfect solution for a wide variety of applications.
sensor requires no calibration and offers a superior probe
design over similar devices. The unique single-prong probe
design minimizes material buildup problems associated with
tuning fork designs. The reinforced stainless steel probe construction
allows use with a wide range of materials.
ability to detect a wide variety of material densities makes
the PZP an attractive solution for many applications. The PZP
is often applied in ultra lightweight applications due to its
exceptional sensitivity to materials as light as 1.5 lb/ft(3).
However, the PZP is also a proven performer for materials up
PZP offers many advantages over alternative technologies. The
vibrating probe principle can eliminate problems associated
with temperature, humidity and material changes, while providing
state-of-the-art electronic reliability and accuracy.
The TrueCap® Model MK-2
RF Capacitance point level probe is designed to provide a superior
and stable sensitivity threshold making it suitable for a variety
of powder / bulk solids and some liquid or slurry applications.
Advanced features of the Model MK-2 include: > Automatic immunity to material build-up on
the probe by its driven shield design > Push-button calibration > Enhanced temperature compensation > Maximized reliability via smart sensing algorithms
like “self-validating” fail-safe protection > Visible status LED on ordinary location units > Versatility through a variety of configuration
options including: hazardous location version, split architecture
design, quick-connect process connection, stub probe, cable extensions,
solid extensions, Nylon® probes, Ryton® - equiv. probes,
A practical application for the TrueCap would be to use this level sensor where
a residual material build-up on a different sensor would cause a false material
Principle of Operation for the TrueCap RF Capacitance Level
The vessel wall and the active probe element establish an impedance reference
between each other when exposed to air which has a dielectric constant of 1.
When materials with a dielectric constant greater than 1 are in close proximity
to the probe, the impedance of the sensing field between the sensor and the vessel
wall will change. Once the amount of change exceeds a threshold that was electronically
determined during the calibration process, an output relay will either be energized
or de-energized depending upon the position of the fail-safe selector on the
probe’s electronic circuit board. A change of as little as .5 pico-farad
is all that is necessary for the probe to sense the presence of material.
