IL - Never before
has finding the right point level sensor been
so easy. Monitor Technologies Point Level Interactive
Product Guide is a six CD multi-media experience
not to be missed.
first CD begins with a unique question and answer
session to determine the Monitor Point Level
product best suited to a specific application.
From there the user is directed to one of the
four product CDs. Contained on each product CD
is an in-depth discussion of the product’s
value, technology, applications, features, installation,
final CD will pull together all of the information
on the previous CDs and add more exciting features.
One such feature is the ability to create a model
code and email a request for quotation directly
Interactive Product Guide is a part of Monitor’s SecureCare(SM)
customer service. SecureCare is
unequaled education, service, and support that
provides the customer with durable instrumentation
having the lowest total cost of ownership. Each
product CD contains a presentation on SecureCare and
the philosophy behind it.
six CD set will be released in stages in 2004.
The first set available in January 2004 includes
the first two CDs in an attractive case with

IL - Using industry-first magnetic
sensing, Monitor’s SafePoint® is
a “true” fail-safe rotary paddle bin level
monitor. The SafePoint provides
the ultimate in performance wherever critical continuous
operation must be ensured.
be a “truly” fail-safe device, the SafePoint monitors
both material presence and its own electrical and mechanical
operational status on a continuous basis. An indicating light
on the top of most units provides local visual indication
of operating status. Additionally, the SafePoint has
separate outputs for material sense and unit status (fault
the SafePoint bin
monitor is an evolution in rotary paddle technology, it continues
to use proven operating techniques. Unlike many other available
paddle units, the SafePoint incorporates
a feature that automatically shuts off its motor when the
paddle is in a stalled condition. This extends the life of
the unit and minimizes maintenance.
wide variety of process connections, accessories and configurations
are available including hi-temp models and models with hazardous
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.
