Dusty-Dirty-Hot-Nasty – Extreme
Conditions, No Problem
Elburn,
IL –Monitor Technologies LLC is
pleased to introduce the SiloPatrol® SE, the Second
Edition of its industry leading SiloPatrol® inventory
management system for bulk solids storage! The
SiloPatrol® SE is the next generation of 21st
century smart cable-based level measurement sensors
and extends Monitor’s ability to provide
the most reliable bulk solids inventory management
solution at the best value, even in the most harsh
and dynamic of conditions.
SiloPatrol SE uses time-proven weight and cable technology and combines Hall
effect sensing techniques (patent pending), microcontroller technology, state-of-the-art
optics and SMT (surface mount technology) to produce a rugged, reliable and accurate
measuring system in challenging extreme environments.
SiloPatrol SE uses the patent pending Hall effect sensing techniques to provide
measurement diagnostic information, allowing the SiloPatrol SE to make decisions
ensuring accurate and reliable measurements, even during harsh dynamic conditions.
Other advanced aspects of the SiloPatrol SE product line include a new split-compartment
enclosure to isolate electronics from the process, a relocated process seal for
fast and easy maintenance (if required), the availability of a standalone analog
transmitter version with automatic measurement updates, and an AC/DC pulse output
version. A programmable relay output for the analog output version is also
available. All versions are provided with a lockout input to inhibit measurements,
an industry best measurement resolution of 0.01ft (3mm), and a freeze-resistant
mounting flange. The unit is available for use in Ordinary and Hazardous
locations.
A choice of operator interface exists, including the latest generation of SiloTrack™ inventory
management software, Version 3.5, now ready to interface with Monitor’s
line of Flexar™ guided wave radar level sensors as well as the new SiloPatrol
SE sensors.
According to Joe Lewis, Vice President - Marketing & Sales, “with decades
of experience in cable-based technology our customers have come to expect industry
leading technology and service from Monitor even in the most difficult environments. The
SiloPatrol SE is no exception.”
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
is located in Elburn Illinois, give us a call today and let us put our creative
solutions to work for you!
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.
