Rockwell Automation introduces new Controller to simplify Machine Safety

Manufacturers and equipment builders are looking for ways to simplify and standardize safety across their machines and systems. With the new Allen-Bradley Compact GuardLogix 5370 controller from Rockwell Automation, users no longer need separate networks and controllers for safety and motion in applications with up to 16 axes. This makes it easier to design safety into a wide range of standard and custom machines, and results in simpler system architectures.

“The new Compact GuardLogix 5370 controller has all the performance capabilities of our popular Allen-Bradley CompactLogix 5370 controller, while also providing integrated safety and motion on a single EtherNet/IP network,” said Ming Jing Ye, global product manager, Rockwell Automation. “When safety, motion and standard control are combined into one package, configuration is easier, wiring is reduced and users get better diagnostics. Ultimately, it helps increase machine uptime and plant productivity.”

The Compact GuardLogix 5370 controller also helps users meet global safety standards. It achieves Safety Integrity Level 3, Performance Level e and Category 4 – the highest ratings for machine safety. When used in combination with the Allen-Bradley Kinetix 5500 servo drive or the Allen-Bradley PowerFlex 527 AC drive, users have integrated safe torque off on EtherNet/IP.

As with other Logix controllers, engineers use the Rockwell Software Studio 5000 software to configure the Compact GuardLogix 5370 controller and develop all elements of their control system. Data can be defined once, and then easily accessed and re-used across different machine types to speed system development and commissioning.

In addition, a single programming environment for both safety and standard control removes the need to manually manage separate standard and safety memory, or partition logic to isolate safety.

The Compact GuardLogix 5370 controller, being manufactured in Singapore, also includes dual Ethernet ports to support both linear and device-level-ring (DLR) network topologies. Built-in energy storage removes the need for batteries, and a removable 1-GB Secure Digital (SD) card improves data integrity.

Rockwell Automation also will be releasing an on-machine option later this year – the Allen-Bradley Armor Compact GuardLogix 5370 controller. This option allows users to place the controller closer to the application or onto the machine, which eases installation, commissioning and troubleshooting. The on-machine controller is IP67-rated for wash-down protection and includes quick-connect cabling to ease system wiring.

Rotork Schischek compact explosionproof valve actuators selected for a petrochemical analysis

Rotork Schischek compact explosionproof valve actuators have been selected as the reliable solution for a critical petrochemical analysis process. Ecopetrol is the largest petroleum company in Colombia, engaged in oil and gas exploration, production and refining. The company uses Near Infrared Spectroscopy (NIR) to perform quantitative sampling separation of hydrocarbons. The process separates the hydrocarbons into four chemical groups – alkanes, aromatics, resins and asphaltenes.

Central to the operation of the process, sets of small two and three-way fast acting ball valves are used to gather the samples for analysis and precisely maintain the pressure, flow and temperature through the spectrometer.

Swift valve operation (typically less than three seconds) is essential to maintain the characteristics of the media for accurate sampling. Additional application constraints involve restricted spaces around valves, the hazardous area classification and requirements for failsafe operation, end of travel indication and low power consumption.

After considering the other options, Ecopetrol concluded that the electric Schischek actuator could satisfy all these demands with a reduced maintenance requirement in the demanding operating environment. Almost 100 Schischek RedMax actuators with associated hardware have been installed; the actuators are certified for Zones 2 and 22 hazardous area operation, environmentally protected to IP66 and equipped with self-adaptable 24 – 240V AC/DC power supplies. RedMax actuators are one of a range of electrical products designed by Schischek for explosionproof and non-explosionproof applications in the worldwide industrial, HVAC and marine industries.

Rotork control valve actuation passes the glass making test

Following extensive testing, leading glass container manufacturers are specifying the Rotork CMA electric actuator for a critical valve control function in the glass making process. The valves are used to control the temperature and pressure in the furnaces by regulating the air and gas mixture with extreme precision. Maintaining a constant temperature and pressure is essential for energy efficient glass making. Traditionally, the industry uses various pneumatic and electric actuators for the modulating and isolating valves involved, but has recognised the need for a more reliable and energy efficient universal solution for this application.

Tests have demonstrated that the CMA out-performs existing equipment, providing improved precision, reliability and energy savings in a compact and easy to set product that is available in a range of sizes that suits all the various valve types encountered. In addition, the CMA’s versatile ability to interface with industry-standard 4-20mA or RIRO (Remote In Remote Out) control signals enables plants in different countries to standardise on the same product.

Furnace revamps, usually taking place after a period of ten years operation, provide the opportunity to introduce the upgrade, which typically involves up to forty valves on each furnace. Following the success of the tests, several hundred ATEX certified explosion proof CMQ250 and CMQ500 actuators have been installed during revamps around the world.

Yokogawa Meters & Instruments Releases AQ6376 Optical Spectrum Analyzer

Yokogawa Meters & Instruments Corporation announces that it has developed the AQ6376 optical spectrum analyzer and will release it on February 16. The AQ6376 has a wide dynamic range and can perform precise, high resolution measurements of the optical spectrum of laser light in the 1.5–3.4 μm wavelength range. The AQ6376 is a bench-top analyzer that uses dispersive spectroscopy*1 and supports the 3-μm band, an industry first.

An optical spectrum analyzer is a measuring instrument that resolves the wavelength components of optical devices such as semiconductor lasers and fiber lasers in order to assess their properties. The AQ6376 will help to improve the efficiency of 3-μm optical devices and accelerate their adoption in fields such as environmental measurement and medicine, where they already are a topic of considerable interest.

Development Background:
In recent years, laser absorption spectroscopy*2 has entered wide use in the environmental measurement field for the detection of gases such as carbon oxides (COx), nitrogen oxides (NOx), and hydrocarbon gas (CxHy). Although 2-μm semiconductor lasers have mainly been used as the optical source in such applications, there is an increasing need for 3-μm lasers because these gases absorb more light at longer wavelengths. Optical lasers are also being gradually introduced in the medical field, where the need to analyze substances that contain water is driving demand for 3-μm fiber lasers. Accordingly, there is a growing need for a tool that can precisely measure optical spectra in the 3-μm band.
