March 2002: CD Catalog • Rotary Paddle


CD Catalog Now Available


Elburn, IL - Monitor continues to "Set the Standard for Supplier Excellence" by offering their product catalog on a convenient business card size CD.

Utilizing a web browser and Adobe Acrobat Reader, the Monitor catalog combines easy-to-use navigation with product information and technical support. Internet access is not required to view the catalog. For users who do not have Adobe Acrobat Reader, the catalog provides a link to download the free program.

Contained on the CD are all of Monitor's sales brochures in PDF format. The easy-to-use menus guide the user through Monitor's selection of point level, continuous level, solids flow, particle emission and bin aeration instrumentation.

In addition to reading about Monitor's products, users can also contact Monitor's staff. By filling out an application questionnaire, Monitor's Application Engineers can select the right product for any application. Users can also e-mail Monitor, connect to the Monitor website or initiate a "Live Chat" with a technical support specialist.

Users can run the catalog from the CD or they can install the catalog on their hard drive. Installation eliminates the need to keep track of the CD. A convenient desktop icon ensures that the availability of product literature and contact with Monitor is very easily accessible. Installing the catalog also allows the user to easily update their catalog through their Internet connection. By filling out a short registration form, customers will receive e-mails when updates to the catalog are available. These updates are then installed on the user's hard drive.

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.
