While majority of safety instrumented functions utilize a valve assembly as the final element a fair number use electric final elements. There is less data and experience available for electric final elements making the design and maintenance areas of the lifecycle more challenging. This webinar will review some of the more common electric final elements, the data available for modeling them, and some of the considerations to include when designing them into safety systems.

One of the fundamentals of the Probability of Failure on Demand (PFDavg) calculations in SIL verification analysis, is the concept of a constant failure-rate during useful life of the equipment. Probabilistic calculations assume that the failure rate of the devices used in a Safety Instrumented System 〈SIS〉 remains constant during…
exida, the global leader in functional safety certification for the process industries, has certified Emerson Process Management Valve Automation, Inc. TEC2000 with TEC2 Electronics (SIL Option) Electric Actuator for functional safety, ensuring it meets the functional safety requirements for Safety Integrity Level (SIL) 3 capability per IEC 61508: 2010. “TEC2000…
This is the second in a series of three webinars on Functional Safety Management Planning. Part 2 compares features of some methods for risk assessment, IPL allocation and SIL determination. Contents for the Safety Requirements Specification (SRS) are listed with some frequently overlooked elements highlighted. Requirements for software development and testing are summarized and tips for setting owner expectations are provided. Finally, lifecycle verification requirements are enumerated and an approach to implementation is suggested.
ALARM MANAGEMENT BEST PRACTICES SEMINAR “Getting your Alarm Management / Alarm System Under Control” Emerson Automation Solutions and exida are hosting a FREE Alarm Management Seminar to learn how to apply alarm management best practices to DeltaV alarm systems on Friday 14th July 2017 in Middlesbrough, UK. The seminar will…

Calculating the spurious trip rate for a single Safety Instrumented Function is rather trivial. However, in many cases one would like to know the frequency of spurious trips of the entire unit. This can be easily calculated within exSILentia. This webinar will review concepts of spurious failures, spurious trip rate vs. mean time to fail spurious as well as how to use exSILentia to obtain an accurate unit spurious trip rate.
exida's Eric Scharpf will be leading a keynote presentation and workshop at the 2nd Safety Control Systems & Hazardous Areas Conference in Auckland, New Zealand on August 22 & 23, 2017. Every year, industry experiences catastrophic fires, explosions or toxic releases. These events can result in injury, loss of life…
Safety certified transmitters often signal a failure detected by their excellent diagnostics via sending the current output levels to “Out Of Range.” If the safety PLC is correctly configured to interpret these currents, safety can be improved and the false trip rate can be reduced. This webinar will explain how to configure the Safety Transmitter Interface.
