April 2003: Free Demo CD • Rotary Paddle Bin Monitor
IL - SiloTrack™ Inventory
Management Software Version 2.0 provides users with an
unsurpassed flexible graphical interface for use with SiloPatrol® Model
SMU "smart" sensors.
Together SiloTrack Server
and Client software can provide inventory management to
a virtually unlimited number of users via LAN, Internet/WAN
or Dial-up modem. Users of the SiloTrack system
can be both internal and external to a facility. This allows
for easy implementation of remote inventory monitoring
and vendor managed inventory applications.
enhanced features include the ability to export history
or alarm data, receive alarm notification via e-mail, fax
or pager, and to initiate analog/relay outputs via the SiloPatrol Auxiliary
Output Enclosures. Additionally, SiloTrack can
setup auto, manual or auto/manual measurements and four
alarms and relays per silo. SiloTrack also
displays distance, level, volume, weight, percent-full
values, alarm, relay and sensor status.
free demo CD includes BOTH the Server and Client software
packages (sold separately) to demonstrate the simplicity
of use and functionality of using SiloTrack V2.0
in multiple PC LAN or remote access environments.
For A Variety of
Bulk Solid Applications
IL - Monitor Technologies‘ line
of rotary paddle bin monitors consists of the most reliable,
versatile and economical point level control sensors available
for detection of dry bulk materials.
many other available paddle units, Monitor's rotary paddle
level indicators incorporate a feature that automatically shuts
off the motor of the unit when the paddle is in a stalled position,
which both extends the life of the motor and minimizes maintenance.
Monitor's paddle units also have a built-in slip clutch to
protect motor and drive gears from excessive forces and longer-lasting
sealed bearings. Additionally, the paddle units' housing is
NEMA 4 and an explosionproof unit is also available.
different material densities, particle sizes and flow characteristics
require specific paddles for optimum performance, Monitor Technologies
offers a variety of interchangeable paddle assemblies to fit
most bulk solid application needs. Additionally, Monitor offers
a high-temperature unit that can be used in applications where
temperatures reach as high as 750° F.
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.
