April 2003: Free Demo CD • Rotary Paddle Bin Monitor



Elburn, 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.

Some 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.

The 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.

Model SFI
Rotary Paddle Units
For A Variety of
Bulk Solid Applications

Elburn, 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.

Unlike 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.

Because 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.

Spotlight: RF Capacitance Level Sensor
TrueCap Level SensorsTrueCap Light  
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.
