Optional
Hycar® Protective Cover Enhances Durability of
Diaphragm Level Switch
Elburn, IL - The optional Hycar® (rubber
nitrile) cover is designed to provide Monitor Technologies'
Binatrol® Model G series diaphragm level switch
with additional durability for use with more abrasive
dry materials. The Binatrol diaphragm level switch
is a reliable, low maintenance and cost-effective way
to monitor high, low and intermediate levels of powder
and bulk solids in storage bins, hoppers, silos, and
vessels. The diaphragm level switch can also be used
to detect plugged or backed-up conveyor chutes for
some applications.
The Binatrol® is a surface mounted, minimally intrusive switch that makes
it ideal for vessels limited in size or internal clearance. The Binatrol is installed
to allow its sensing diaphragm to be exposed to the material being detected. Bulk
material contacting the unit transfers force to an internal lever arm assembly,
which than causes the dry contact SPDT 15 Amp switch to be activated. Common
material applications for the Binatrol include grain, seed, wood chips, sawdust,
cement, powders, resins, pellets and more. Monitor offers a variety of diaphragm
bin level indicators that can be configured with various switch sensitivities,
diaphragm materials and approval ratings. Also, the Binatrol diaphragm
switch requires no input power. For more details, please visit www.monitortech.com ,

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,
etc.
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
level indication.
Principle of Operation for the TrueCap RF Capacitance Level
Probe:
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.
