Authors: Enrico De Carolis, Mike Johnson As packaging line machinery has become more sophisticated, it’s also become more complex. This increased complexity, coupled with a high number of interactions between operators and machines, increases the potential for safety incidents. For example, in the packaging world, production lines may stop for manual loading 10-30 times per […]

Storage tanks holding volatile fluids must have reliable level measurements to avoid unsafe overfill conditions. A Control Engineering Asia article, Wireless vibrating fork technology enables Hengyang Petrochemical to implement cost-effective overfill prevention solution, describes how this petrochemical producer sought to reduce the risk of overfill conditions. The plant had existing non-contacting radar level measurement devices […]

Safety instrumented systems provide a layer of protection beyond the control system to safely shutdown the process during abnormal situations. A safety instrumented function (SIF) or “safety loop” includes the sensing device, logic solver and final control element to perform safety function upon demand. Flow measurement devices are often the sensing devices in these SIFs. […]

Safety instrumented systems (SIS) include the sensor(s), final control element(s) and logic solver(s) for each of the safety instrumented functions (SIFs) in the SIS. To verify the SIFs are performing the amount of risk reduction intended for their application, they must be periodically proof tested. PCN Europe magazine interviewed Emerson’s Teddy Tzegazeab on how proof […]
