New Field-Mounted Gas Chromatograph Offers Expanded Choice for Chemical, Oil and Gas Applications
ABB (Switzerland) has expanded its process analyser offering for chemical, oil and gas applications with the introduction of the new PGC1000 field-mounted process gas chromatograph. Suitable for measurement of hydrocarbon groups C1 to C9+, inerts and hydrogen sulphide, the PGC1000 provides a compact measurement solution for a wide variety of gas processing applications.
Measuring just 16 inches front to back and weighing 28 pounds, the PGC1000 offers a highly compact footprint, opening up new installation possibilities. The single module contains all of the necessary switching valves, columns and detectors, with no metal moving parts. As a field-mounted device, it can be installed outside near to the sampling point and can be used in temperatures from -18°C up to 55°C, or - 40 to 55 where a cold weather enclosure is used. The device can be fitted either directly onto two or 12 inch pipelines or onto a pole if required.
The PGC1000 provides a choice of sampling options. Up to four different gas streams can be sampled at a time. Users have the option of a single auto calibration stream and three sample streams or two auto calibration streams and two sample streams. A standard sample conditioning module is also supplied to handle gas streams that need additional filtering or where sample transport lag times need to be minimised.
A key feature of the PGC1000 is its ease of use, enabling it to be used by operators with little or no experience of using process gas chromatographs. Programming and operation is achieved via a graphical user interface software package on a laptop or workstation PC. Combining a Windows-based interface with a program specially written for the PGC1000, the software provides a simple yet powerful tool for operations, diagnostics and data handling.
The PGC1000 retains historical data which can be subsequently used for audit trails, maintenance and troubleshooting, including verifying transmitter operation. Via the operator interface, users can configure the period for which data needs to be retained. The default memory configuration enables the details of up to 480 analysis cycles to be stored, including parameters such as temperature and pressure, noise values and alarms. This data can be collected either via a remote communication link or via the laptop or workstation interface.
Basic data can also be accessed via the PGC1000’s ¼-inch VGA display screen. Via this display, the user can perform many of the operator functions without the use of a laptop or PC. Magnetic interface technology enables the user to handle basic programming tasks through the PGC1000’s explosion- proof glass, eliminating the need to open up the device and compromise its safety protection.
Maintenance is also simplified. Both the PGC1000’s hardware and software feature easily replaceable electromechanical modules, making the unit simple to repair or upgrade. Diagnostic software and wizards also make it easy to trace any faults.
The PGC1000 is fully certified to leading safety standards, making it suitable for use in a range of potentially explosive and hazardous areas. As well as measuring hydrocarbon gases, the device is also ideal for monitoring fuel gases such as natural gas, synthetic gas, methane, and / or bio-gas.

Reader Reply Card No 116 Next Generation of OPC Standard Released
Yokogawa Electric Corporation (Netherlands) have announced the release of the OPC Unified Architecture (UA) client for the company's FAST/TOOLS version R9.05 Web-based SCADA system.
The Unified Architecture is the next generation OPC standard that provides a cohesive, secure and reliable cross-platform framework for access to real-time and historical data and events. Yokogawa's FAST/TOOLS OPC UA Client is the first SCADA software which meets the requirements of the OPC Certification programme in terms of interoperability and robust performance.
OPC relates to Open Productivity & Connectivity in industry - and especially automation of the enterprise systems that support industry. Interoperability is assured through the creation and maintenance of open standards specifications such as OPC, and there are currently seven standards specifications completed or in development.
Using fundamental standards and technology from the general computing market, the OPC Foundation adapts and creates specifications that fulfil industry-specific needs. OPC will continue to create new standards as needs arise and to adapt existing standards to utilise new technology.
OPC UA Certification will become a requirement for all OPC UA Servers and OPC UA Clients. By making certification mandatory, the overall quality and experience of OPC UA based products will be much more satisfactory, with significant cost savings for systems integrators and end-users who use them.
Nobuaki Konishi, Vice President and head of Yokogawa's IA Control Systems Business Headquarters, comments: Yokogawa is a market leader in the process automation industry with leading-edge products and services, and OPC UA is a major step forward in this sector.
Yokogawa is the first industrial automation SCADA vendor to release an OPC UA client certified to meet the latest OPC UA standard, he added: This is a major opportunity to reinforce our proven expertise to the industry and our goal of providing the highest quality of products and services for sustainable solutions to the industrial automation sector. The FAST/TOOLS web-based real-time management and visualisation software brings revolutionary changes to real-time process information intelligence.
Main target markets and applications for the OPC UA client for FAST/TOOLS include process monitoring and asset management in industries such as oil & gas, petrochemicals, chemicals, power, pulp and paper, pharmaceuticals, food, iron & steel, and water and wastewater treatment.
Since 1978, Yokogawa has sold more than 10,000 FAST/TOOLS packages worldwide for use in all types of SCADA and process management projects. Yokogawa continually endeavours to meet its customers needs by providing highly reliable enhancements to this product based on leading-edge technology.

Non-Contact Temperature Measurement System
Raytek (Germany), a specialist worldwide provider of infrared thermometry, introduces the Equipment Monitoring System (EMS), a non-contact temperature measurement system that enables round-the-clock condition monitoring of actively powered components or operating machinery, supporting predictive and preventive maintenance.
Detecting temperature rises or spikes on the surface of equipment, the Raytek multiple head solution acts as an early warning device for critical assets, including switchgear and electrical cabinets, electrical motors, pumps, furnace controls and heating elements. It gives operators notice of thermal issues as they begin to occur, as well as recording data for trend analysis. Early detection of heat-related faults and failures, along with maintenance performed as needed and not when estimated, result in reduced maintenance costs, less waste from unexpected downtime and higher safety.
Temperatures are displayed on the system's LCD control module and/or remotely through the PC-based, Windows 7-compatible DataTemp Multidrop software.
