Rotary Paddle Bin Level Indicator
Product Line Does It All
Elburn, IL -- Monitor Technologies
LLC is pleased to announce that it's line of rotary
paddle bin level indicators is the broadest and most
state-of-the-art available and is virtually universal
in application for monitoring the presence and absence
of powders and bulk solids. The "rotary
paddle unit" first came on the market in the mid
1950's and since 1958 Monitor Technologies has been
leading the way.
Monitor's rotary paddle product offering consists of the Model KA/KAX Bin Monitor
and the SafePoint(R) Fail-Safe Bin Monitor unit. Both models use the industry-first
Monitor designed motor shut-off feature to enhance life and minimize wear. In
addition, both the KA/KAX and SafePoint models use a twist-on/off cover so there
is no need to mess with bolts, and this makes the initial install and any maintenance
quicker and easier to perform.
The Model KA/KAX units meet ordinary and hazardous location requirements, can
detect bulk solid materials from 5 pounds per cubic foot and up, and can be used
in applications where the process temperature can be up to 750 degrees F. These
units are also very cost effective with a complete system starting at around
The SafePoint(R) rotary paddle unit is a unique fail-safe rotary paddle unit
that uses patented technology with Hall-effect sensors to continuously monitor
the electrical and mechanical aspects of the sensor itself. The self-validating
techniques combined with patented technology, ordinary and hazardous area approvals,
high process temperature handling capability, a twist-on/off cover and a purchase
price around $300 make this unit the most viable device for critical point level
measurement applications wherever bulks solids are concerned.
Monitor Technologies LLC is a leading supplier of level, flow, particle emission
and aeration instrumentation for the worldwide powder and bulk solids market.
The experience and market knowledge gained over five decades has earned Monitor
a reputation for providing high quality and reliable product solutions. Monitor

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.
