Radar Transmitter

First rate, fully friendly,… less costly


The new Model R82, 26 GHz Two-wire non contact Radar Transmitter from Magnetrol is a high performance, yet low-cost level transmitter based on the concept of Pulse Burst Radar. Short bursts of 26GHz microwave energy are emitted and subsequently reflected from the liquid level surface. Liquid level is then calculated by applying the user's tank height and sensor Offset values.

The new economical design features advancements that now make radar cost-competitive with its loop-powered, ultrasonic competition. The company is thus rendered able to compete with any instrument manufacturer in a wide variety of level and volume applications.

The Model R82 can be used in thousands of generic, storage applications. The design lends itself to measuring within inches of the tank top. The encapsulated horn in Polypropylene or Tefzel® allows it to be used in the most corrosive media.
The Model R82 can handle process temperatures from -40°C to +93°C and from full vacuum up to 13.8 bar within a measuring range up to 12.2m.
Its internal launcher adjustment allows beam orientation without removing the Model R82 from the vessel.

Another feature of the Model R82 is the standard 4-20 mA output with HART® which can be used for data transmission, configuration and diagnostics. The PACTware™ program provides extensive diagnostic capabilities including capture of echo waveforms, viewing of trend data and all transmitter configuration parameters.

The unit is capable of measuring the tougher applications of turbulence, foam, heavy vapors and buildup on the antenna and/or applications, it measures effectively in ranges up to 20m.

ISA 100-11 tour

Newly approved standard works!

ISA 100-11 won approval a few weeks before ISAExpo 2009 and on the day before the show a tour of the Arkema chemical plant near Houston (TX US) showed a multi vendor application which was installed just days after the approval and is fully ISA100 compliant.

    Companies like Gastronics, Honeywell, Nivis, Wilson Mohr, Wireless Access Solutions (formally Gooch Engineering) and Yokogawa were represented in the hardware and others apparently are to be added shortly.

    Parameters covered included temperature, pressure, contact closure, valve positioning, gas detection, corrosion detection, and others. The vision is of a single coherent architecture that is scalable to cover all of these applications, plus many more, with high reliability across the site. The entire site is currently covered by two backbone connections and sensor meshing.

    This approval gives the go ahead to companies to proceed now with equipment now that the standard is approved and available. Companies like, say, Gastronics, which pioneered the first all-in-one wireless gas monitor in 1999 where the radio is an integral part of the gas monitor. Their True Wireless gas detection system offers the most economical solution for monitoring gases from remote locations. Now they can say to their customers "This is fully complient with the standard!"

    Indeed Bud Dungan, Gastronics' President said “The concept of an industrial wireless communication standard with true interoperability and mesh networking capabilities is compelling.... we have high expectations for market uptake of these products.” (Gastronics joined ISA Complience Institute as we reported 28th August on our News Page.)

    The best and most succinct comment came from one of the participants in the tour. Gary Mintchel from Automation World tweeted "...ISA100.11a wireless sensor network technology. Guess what? It works."

    What else can one say!

    Combined certification for functional safety, security and availability
    Functional Integrity Certification™ Benefits Automation Vendors and Customers

    exida claims to be the first company to offer a holistic evaluation of the most important attributes of an automation product – functional safety, functional security and availability.

    Introduced today at ISA Expo 2009 in Houston, exida’s Functional Integrity Certification™ is the only independent, third party assessment that examines functional safety, security and availability attributes of an automation product through assessment of its design, testing and manufacturing. The program also scrutinizes how a product performs under stress, in the field and over time.

    “This is a win-win for everyone,” says Dr. William Goble, exida principal partner. “Functional Integrity Certification helps automation suppliers demonstrate the safety, security and reliability of their products. This also saves engineering time and money through a streamlined, single source assessment process. In turn, prospective buyers are provided with objective information to help guide their purchasing decisions.”

    “This program follows our open assessment policy,” says Rainer Faller, exida principal partner and CEO of exida GmbH. “Technical assessment reports are openly available on the exida web site.”

    For functional safety, a product and its development process are evaluated per the international standard IEC 61508 to determine its Safety Integrity Level (SIL). The SIL level is a measure of the probability that a product will perform its intended protection function when needed.

    Functional security assesses a product’s resiliency to intentional or accidental manipulation that could cause it to behave differently than was intended. A combination of network robustness testing, security feature assessment and software development process assessment helps detect and avoid vulnerabilities and systematic design faults. The certification is based on the ISA Security Compliance Institute (ISCI) Embedded Controller Security Assurance (ECSA) test specification.

    Finally, an availability assessment ensures the dependability of automation products in critical applications. exida uses modeling and probabilistic methods, combined with empirical data, to help predict product reliability.

    Themal Imager

    High Definition Thermal Imagers deliver 320x240 resolution
    Optional lenses and field-changeable batteries add versatility

    Fluke has introduced the Fluke Ti32 and TiR32 Thermal Imagers, the first industrial grade, high-performance imagers on the market to incorporate a powerful 320x240 sensor to provide high-definition, strikingly crisp, detailed images for under £7,200 (approx €7900). Their superior image quality helps to identify even the smallest temperature differences that could indicate problems. With their patented IR-Fusion® technology, users can marry high-precision thermal images with visual (visible light) images in full screen, picture-in-picture or blended views for enhanced problem detection and analysis. IR-Fusion is the only solution available with physical parallax correction, which enables perfect alignment, pixel by pixel, of both infrared and visible images. Fluke products are the only thermal imagers on the market to incorporate IR-Fusion in both camera and software.

    The Ti32 Industrial Thermal Imager is designed and priced to deliver unprecedented performance for troubleshooting and preventive maintenance of electrical installations, electro-mechanical equipment, process equipment, HVAC/R equipment and more. The Fluke TiR32 Thermal Imager for Building Diagnostics is designed and priced to deliver unprecedented performance for building envelope, energy audit, restoration and remediation, inspection and roofing professionals.

    Users can record voice comments of up to 60 seconds with every image taken by the these units. They feature a three-button menu designed for intuitive operation and navigation with a push of the thumb, on-screen emissivity correction, transmission correction and high temperature alarm (dew point temperature alarm on the TiR32). Each unit comes with two field-swappable, rechargeable batteries that enable virtually continuous imager use. Optional telephoto and wide-angle lenses are available to bring distant and wide views into sharp focus.

    Fluke SmartView® Software (with free software upgrades for the life of the product) is included with each thermal imager. SmartView software is a modular suite of tools for viewing, annotating, editing and analysing infrared images that fully supports Fluke IR Fusion technology. It enables users to edit images in five viewing modes and generate customised professional reports in a few steps. Fluke 3D-IR™ three-dimensional viewing makes hot or cold spots “pop out” of the background for easy viewing and analysis.

    These rugged Thermal Imagers are tested to withstand a drop of 2 meters, and are IP54 rated to withstand water and dust. They have a widescreen, full colour LCD display, increased thermal sensitivity (≤0.05°C at 30°C target temperature) and a temperature measurement range of -20°C to +600°C for the Ti32, -20°C to +150°C for the TiR32.
