    New microphone sets concept


    G.R.A.S. Sound & Vibration (G.R.A.S.) has announced the release of a new microphone sets concept where focus is on simplicity, reliability and robustness.

    Uniquely designed based on customer feedback, G.R.A.S. Type 46 Microphone Sets offer a new approach to acoustic measurement data integrity, by reducing user setup and handling errors and improving overall reliability. Sets are available in ¼” and ½” diameters and in free-field, pressure and random incidence types, with specifications developed to support the most common acoustic measurement parameters. They are assembled in a dust-free environment to avoid contamination of the microphone and preamplifier interface; are calibrated together as a single unit; and are sealed with a removable label, for seamless integration into both single- and multi-channel applications. By using these combined sets, mix-ups of microphones, preamplifiers and system calibration data are alleviated.

    G.R.A.S. Type 46 Microphone Sets are delivered with individual calibration charts, including sensitivity values and frequency response curves, allowing the sensitivity values to be used directly within system setups. For frequent verification of the measurement chain, a 114 dB sound calibrator is supplied as a sound source. The sets can be connected directly to all pro­fessional measurement systems and are available to support both constant current power (CCP) and 7-pin LEMO inputs. For larger channel count applications, G.R.A.S. Type 46 Microphone Sets also incorporate IEEE 1451.1 (TEDS), allowing for a plug-and-play solution and the ability to identify individual unit properties, types and calibration data, with the added benefits of TEDS onboard memory storage capabilities. In addition, all G.R.A.S. Type 46 Microphone Sets are offered with a 5-year comprehensive product warranty.

    Tune cascade loops from a web browser

    ExperTune, now has the capability to tune cascade control loops directly from the web browser interface of the PlantTriage Loop Performance Monitor. This greatly streamlines the tuning process, according to ExperTune's Founder John Gerry.

    The PlantTriage system monitors control system performance continuously, 24 hours a day. It automatically diagnoses and prioritizes process, control, and instrumentation problems. Integrated analysis and tuning tools improve plant results by focusing effort on the most critical issues.

    Typical cascade control loops involve two instruments, two controllers, and a single control valve or variable-speed drive. Cascade controls are designed to reduce variation, by offering faster response to process upsets. The outer loop provides a setpoint to the inner loop. Unfortunately, says Gerry, "Most cascade loops in plants are poorly tuned, resulting in constant oscillations and interactions between the inner and outer cascade loop."

    The new tools allow users to tune both loops, with a single bump test, directly from a web browser interface. Oscillations are eliminated because the PlantTriage tools select tuning constants that are outside the range of interaction. The new tools are also fully integrated with PlantTriage's "Active Model Capture Technology", so dynamic models and controller tuning can be developed based on normally-occurring events, such as operator setpoint changes.

    Mr. Gerry, a member of the Process Automation Hall of Fame, who will be acclaimed an ISA Fellow at this years Automation Week (4th October in Houston), says "Cascade control, especially cascade tuning, is often mis-understood. These tools make it simple to tune loops the right way, which will help to stabilize plant operations, improving quality and energy efficiency."

    Asia Pacific wireless technology seminar

    The ISA100 Wireless Compliance Institute (WCI) reported outstanding results for its first Asia Pacific wireless technology outreach event, with more than 100 supplier and end-user professionals in attendance.

    Yamatake hosted the event for the ISA100 Wireless Compliance Institute with support from Yokogawa, at the Queen’s Square in the historic port city of Yokohama, Japan.

    WCI members provided a series of presentations on the ISA-100.11a technology, the status of planned additions to the standard, and a live interoperability demonstration using wirelessly networked ISA-100.11a sensor devices contributed by WCI supplier members. Key topics included announcements of successful ISA-100.11a product certifications, the product certification process, and organizational information on the ISA100 WCI.

    The all-day seminar included English-language morning sessions for Asia Pacific supplier organizations, drawing over 80 attendees including Engineering, Procurement and Construction (EPC) companies; and afternoon sessions presented in Japanese for Asia Pacific end-user organizations, with more than 100 people in attendance. Presentations are available in English and Japanese on the institute’s website at www.isa100wci.org.

    The ISA100.11a technology seminar followed three days of internal ISA100 WCI planning workshops to determine initiatives and goals for 2011 and beyond. One of the key items resulting from this year’s organizational planning was the establishment of divisions for regional support and outreach. The Asia Pacific Division is the first to be launched, with division leaders to be identified in upcoming weeks.

    “The results of the Yokohama event exceeded our expectations,” stated Andre Ristaino, managing director of WCI. “It sets the bar for future ISA100 WCI industry outreach events. I was impressed by the level of interest in the ISA100 industrial wireless standard and we are grateful to Yamatake and Yokogawa for their hard work, hospitality and marvelous outcome.”

    The ISA100.11a industrial wireless networking standard is the first in the ISA100 family of standards. This wireless mesh network standard protocol helps supplier companies build interoperable wireless automation control products. As a result, manufacturing sites are able to create, modify, optimize and scale a wireless network quickly, cost-effectively and seamlessly.

    The ISA100.11a certifications are a significant milestone for WCI, and the certification provides users with the assurance that registered ISA100.11a devices will interoperate and adhere to their requirements. Manufactures have made their own product announcements about these certifications and, with a planned maintenance review underway, the ISA100.11a standard is expected to be submitted to the International Electrotechnical Commission (IEC) for approval in early 2011. Certified products already deployed can maintain compliance with a simple over-the-air firmware upgrade provided by the vendors—a clear example of one of the future-proof benefits of this standard.

    Planned additions to the ISA100 family of standards include support for backhaul functionality, factory automation and other key-use cases.

    Reliable and cost saving shutdown protection for underground gas storage project in China

    Self-contained emergency shutdown systems installed at wellhead where external power sources are not available.

    Emerson’s Bettis PressureGuard self-contained emergency shutdown systems are protecting the Dazhangtou natural gas storage reservoir project in Tianjing, ChinChina National Petroleum Corporation (CNPC) has selected Bettis™ PressureGuard™ self-contained hydraulic shutdown systems from Emerson Process Management for installation on the Dazhangtou natural gas storage reservoir project in Tianjing, China. Seven PressureGuard systems, which require no external power source, will protect the gas storage reservoir by closing gate valves when a high or low pressure threshold has been reached.

    The Dazhangtuo reservoir is the first gas storage facility in China. It strengthens the peak-gas adjustment capacity of the Shan-jing natural gas pipeline, which extends 585 miles from Yulin, Shanxi, to Beijing. Gas that is not needed immediately is diverted into underground storage facilities. This allows excess gas delivered during the summer to be made available to help meet the increased demand in the winter.

    The Bettis PressureGuard systems are being installed in the wellhead area of the gas storage facility, where there is no electrical power. This is an ideal application for the spring-based PressureGuard shutdown systems because no plant air, fuel gas, electricity, or expensive nitrogen back-up systems are required. A self-contained oil reservoir also removes the need for any external hydraulic piping. A Pressure Pilot with Hi-Hi, Low-Low options triggers the system when a pressure threshold is reached.

    The Bettis PressureGuard system offers built-in temperature compensation and pressure relief and has proven to be highly successful in years of field service under some of the most demanding operating and environmental conditions. The actuator can be used with either rotary or linear spring-return hydraulic operators to provide a fail-safe system adaptable to ball, plug, and other quarter-turn valves as well as reverse-acting gate and other linear operated valves.

    The compact 6U PXI form factor offers a cost effective, compact form factor without sacrificing performance for system, board and component test applications. In addition, the GX5960 offers a per-channel parametric measurement unit (PMU) and analog bus access for each I/O channel -
    providing hybrid channel (digital or analog) measurement capabilities. Two module configurations are available - the 32 channel GX5964 or the 16 channel GX5961 which offers guided probe support and static high voltage I/O.

    Both the GX5295 and GX5960 are supplied with the DIOEasy software package, which provides vector editing / display & file import utilities, a virtual instrument panel, and 32-bit DLL driver libraries.

    The GX5295 is available October 15th and the GX5960 digital subsystem is available November 1 and will be presented for the first time in Europe at electronica 2010 (Munich DE 9/12 Nov 2010).

    New book simplifies cascade control

    “Mastering Cascade Control” is a new book released by PIDTutor. It is designed to help technicians and engineers to implement and troubleshoot split-range control applications.

    Cascade control uses two controllers with a single control valve to provide faster, more accurate control response to upsets.It can be used for many different applications, such as heat exchangers, tank levels, and distillation column control. Cascade control is widely used in the process industries, such as pulp and paper, oil and petrochemicals, and mining.

    George Buckbee, President of PIDTutor, and author of the book, says: "I have spent most of my career in manufacturing plants. This is a practical book for plant technicians and engineers, using straightforward rules and guidelines, without the complex math."
    “Mastering Cascade Control” covers all aspects of the use of cascade control. Starting with the basics, the book discusses when to use cascade and when to avoid it, costs and benefits of cascade, how to configure the control strategy, how to commission the system, tune the loops, and even how to train operators and troubleshoot problems. Color illustrations simplify the key concepts.
