Web Seminar
Web Seminar to Help You
with Internet Research

Elburn, IL. —Monitor Technologies LLC is pleased to announce that on March 7, 2005 we will kick-off our 2005 web seminar program with a 30-minute presentation entitled, “Researching the Internet”. In this seminar you will be given practical information to aid you in using the Internet as a research tool. This seminar is designed to help you obtain online results for technical information fast, whether you are a novice or an expert on the use of the Internet.

The Internet has opened up a new world to millions of people and enables you to be your own researcher and find information critical to making decisions that effect your professional career and personal life as well. Yet many engineers look at the Internet as one might look at a field of wildflowers. There is a great deal of material out there, but you still need to pick your way through the huge amounts of weeds and pests to find what you want.

A degreed engineer who has educated himself on how to find information via the Internet will present this seminar. The presenter has spent much of his career as a consulting engineer using the Internet as part of his business. In this 30-minute program he will share with you what he has learned, providing tools and techniques for identifying no-cost online information sources. He will also provide advice on sites that he has frequently used. This will be invaluable to the occasional Internet surfer who may need to locate information quickly, and under pressure.

Monitor web seminars are a free educational service available to anyone registered at the “For Engineers” section of their website. If you are interested in attending this kick-off seminar for 2005, go to, click the “For Engineers” tab on the home page, and follow the instructions to register. If you are already registered with “For Engineers, just click on Register for the Seminar shown under “Monitor News” on the home page. You will receive your confirmation and instructions on how to attend the seminar by email.

Interactive Guide
Industry - Leading Multimedia Point Level Application Guide

Elburn, IL. —Monitor Technologies is pleased to announce the final installment of our Point Level Interactive Product Guide. This industry leading application and product selection tool simplifies the process and helps eliminate misapplications.

CD#5 provides an interactive multimedia review of mechanical diaphragm and tilt switches. Along with CD # 1, 2, 3 and 4, this completes the most comprehensive application and product review selection tool ever produced for this type of products.

The Point Level Guide is a five-CD multimedia educational tool designed to familiarize potential users with the various technologies used for point level measurement of liquids, solids and slurries (rotary paddle, RF capacitance, vibratory and mechanical sensors). Monitor’s unique Application Review Software (CD#1) determines which of these technologies is recommended for any specific user application, based upon information provided in an interactive Question & Answer format.

Monitor offers the Point Level Interactive Guide free of charge as part of its SecureCare customer service program. Monitor believes it is as important to produce tools that help eliminate misapplications, as it is to provide durable and reliable instrumentation.

The new Interactive Point Level Guide CD is available through Monitor and any Monitor Representative. You can request a copy from the Monitor website at

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.
