Never before has finding the right point level sensor been so
easy. Monitor Technologies Point Level Interactive Product Guide
is a single CD multi-media experience not to be missed.
The CD begins
with a unique question and answer session called “Review
My Application”, which is used to determine the point level
product best suited to your specific application. From there you
can view a multi-media product discussion on any of Monitor’s
point level products. Each product discussion contains an in-depth
review of the product’s value, technology, applications,
features, installation, and specifications.
The Interactive Product
Guide can help make your job of selecting point level sensor technologies
easier. The Interactive Guide is
a part of Monitor’s commitment to unequaled education, service,
and support that provides you, the customer, with durable
instrumentation having the lowest total cost of ownership.

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