Flow Level Pressure 39 Enhanced Version of Safety Instrumented System
Yokogawa Electric Corporation (USA) has released an enhanced version of its ProSafe-RS safety instrumented system. This new version, ProSafe-RS R3.02.00, features input/output modules that will operate reliably in the high-temperature conditions typically encountered in desert locations.
Support of an open communications protocol has also been added, enhancing the system’s compatibility with other vendors’ distributed control systems (DCS).
In the oil, natural gas, petrochemical, iron & steel, and other energy and basic materials industries, it is becoming increasingly important to ensure the safety of plant operations to prevent accidents, protect the environment, and be good corporate citizens. Accordingly, there is a growing demand for safety instrumented systems that can detect abnormal conditions and safely initiate emergency shutdowns.
Control devices and safety instrumentation systems are often installed outdoors for monitoring oil and gas wells and pipelines. As many of these facilities are in desert locations, they must be able to operate in high-temperature conditions.
In addition, plant operators who replace their safety instrumentation systems to improve productivity and safety need to maintain compatibility with their existing distributed control systems.
To satisfy these needs for high-temperature resistance and inter-system compatibility, Yokogawa has developed this enhanced version of the ProSafe-RS safety instrumented system.
High-temperature resistant digital and analogue input/output modules have been developed. Previously, input/output modules had to be spaced far apart to prevent the accumulation of heat. While mounted closely together, the new modules can operate at ambient temperatures of up to 70°C (158°F). This reduces the system footprint.
Safety instrumented systems and distributed control systems are not always replaced at the same time. Therefore, ProSafe-RS has been enhanced by adding support for Ethernet-based Modbus/TCP communications with other systems. Modbus is an industrial communications protocol developed by the US company Modicon (now owned by Schneider Electric). This facilitates the flexible connection of the ProSafe-RS system with distributed control systems from other vendors, allowing Yokogawa’s customers a greater range of choice.
Takashi Nishijima, a Director and Senior Vice President, and Head of Yokogawa’s Industrial Automation Platform Business Headquarters, comments: "The latest version of ProSafe-RS was developed to achieve safety excellence at our customers’ production sites, which is one of the aims of our VigilantPlant range of solutions . Safety is the most important consideration in plant operations. With this new version, ProSafe-RS is now capable of ensuring that our customers’ systems work precisely and safely under high-temperature conditions. The tighter connection not only with CENTUM systems but also other vendors’ systems makes it easier for companies to adopt our highly reliable safety instrumented system. We will continue our efforts to develop products that support our customers’ plant operations."
Major target markets and applications include emergency plant shutdown, fire prevention and firefighting in the oil, natural gas, petrochemical, and other process industries. Reader Reply Card No 121 Life Safety Solution Named New Product of the Year
The Accenture Life Safety Solution, a wireless-enabled multi-gas detection system that helps protect workers in potentially hazardous environments, developed by Accenture, Industrial Scientific (USA), Cisco and AeroScout, has received the industrial hygiene product of the year award from Occupational Health & Safety magazine.
The Accenture Life Safety Solution integrates Wi-Fi and location-based technologies with multi-gas (hydrogen sulphide, carbon monoxide, hydrocarbon and oxygen) detectors. It helps companies to remotely monitor incidents and to locate workers in hazardous locations. The solution is designed for environments such as oil and gas refineries, chemical and manufacturing plants, utilities, mines and other locations where dense steel infrastructure can make wireless safety solutions difficult to implement.
“Worker safety is a key priority for a range of industries with operations in challenging working locations,” said Massimo Pagella, senior executive in Accenture Plant and Automation Solutions. “This solution can help mitigate risks by continuously monitoring the environment in the plant and automatically providing feedback on abnormalities to the control centres and to management. Accenture continues to invest in R&D to broaden the range of services and capabilities the solution offers.”
The Accenture Life Safety Solution uses multiple Wi-Fi access points to determine the location of workers. The solution, which is designed, installed and deployed specific to a location, uses a lapel-based wireless four-gas detector, as well as a panic button and a motion sensor to detect when a worker stops moving for a period of time. The solution is based on Accenture’s patent-pending design and integrates Industrial Scientific’s Ventis LS multi-gas detector and Gas Detection as a Service solution iNet; Cisco's Unified Wireless Network and Mobility Services Engine; and AeroScout's Wi-Fi Tags and MobileView location management and user front-end technology.
Raghu Arunachalam, director of emerging technologies at Industrial Scientific, said, “The Accenture Life Safety Solution has brought to market a revolutionary approach to gas monitoring that is capable of overseeing the safety of thousands of employees working across a large plant in real time and from a central location. We are honoured to have this unique, life-saving solution recognized as a New Product of the Year by Occupational Health & Safety magazine.”
The Occupational Health & Safety award program honours the outstanding product development achievements of companies that create products which are considered particularly noteworthy in their ability to improve workplace safety.

ATEX certified Dewpoint Hygrometers can give Early Warning of Potentially Expensive Moisture Problems
Alpha Moisture Systems (UK) manufactures, and distributes, worldwide, moisture analysers for dry gases, including ATEX certified versions suitable for Zone 0 Hazardous Area use.
Model SADPmini-Ex, weighing less than 1.2Kg, is invaluable for carrying out rapid spot checks to confirm current conditions and correct function of on-line systems. When equipped with on-board logging it is ideal for short term continuous monitoring of gas systems, for example during commissioning.
Model AMT-Ex is an Intrinsically Safe 4-20mA Dewpoint Transmitter suitable for continuous monitoring of gases to warn of developing problems, such as drier failure, thus avoiding expensive repairs and down time.
Instruments cover ranges from -110°C to +20°C (-166°F to +68°F) dewpoint and are supplied with a Certificate of Calibration validating the traceability of the calibration to International Standards (NPL/NIST).
The AutoCal facility, common to both instruments, ensures optimum accuracy between laboratory calibrations by enabling users to check the span of the instrument in the field and correct for any deviation.
