Elburn,
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.
The
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, and specifications.
The
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 to Monitor.
The
Interactive Product Guide is a part of Monitor’s SecureCareSM
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.
The
six CD set will be released in stages in 2004. The first
three CDs in the set are available now! This Interactive
Guide is free of charge.
Elburn,
IL - Monitor Technologies' VibraFork™ vibratory
point level sensor for liquids provides reliable sensing
in a wide variety of applications in virtually any industry.
The
vibrating probe principle utilized by the VibraFork overcomes
typical application difficulties associated with changes
in material, electrical dielectric constant, temperature
or humidity. The VibraFork is
easy to setup and requires no calibration. A high excitation
frequency and a unique fork design provide excellent immunity
to external vibration.
The VibraFork line
of sensors has two versions, “Standard” and “Compact.” The “Standard” version
has a traditional instrument housing and provides local indication
using a high-intensity bi-color LED and a relay output.
The “Compact” version
has a compact stainless steel housing with a small local
LED. A choice of outputs, solid state PNP/NPN, 2-wire AC
or intrinsically safe, are also available.
The
probe configurations available with either the “Standard” or “Compact” versions
include the standard probe (4.9 in/125 mm), “SHORT” probe
(2.7 in/69 mm) or pipe extension probe.

Spotlight: RF Capacitance Level Sensor
TrueCap® MK-2
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 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.
