By Plant Engineering Staff October 16, 2008

Invensys Process Systems announced at the ISA Expo in Houston new process safety solutions, including a line of SIL 2-certified pressure transmitters and the achievement of dual seal certification required by the Canadian Electrical Code. The company’s five most popular Foxboro HART version pressure transmitters are now SIL 2-certified by TÜV Rheinland, and all IPS differential, gauge and absolute pressure transmitters meet the new Canada CEC/NEC Dual Seal certification.

“Our customers are requiring higher levels of safety to reduce the risks of human injury, property damage and environmental impact,” said Brian Dickson, IPS vice president of field devices. “By offering solutions incorporating SIL 2 TÜV-certified transmitters with Triconex systems, the number one safety systems solution, IPS provides clients with a very attractive option to meet their health, safety and environmental objectives.”

The company’s five most popular HART version pressure transmitters now meet the SIL 2 TÜV Certification set by TÜV Rheinland. This certification is awarded in part on Safe Failure Fraction numbers and calculated failure rates. The SFF rating is key to the certification and IPS’ new SIL 2 TÜV certified pressure transmitters surpass the 90% rating that TÜV Rheinland commonly requires for qualification for use in safety instrumented systems (SIS) at the SIL 2 level. Further, the mean time before failure rating of the SIL 2 TÜV Rheinland certified Foxboro pressure transmitters is 200 years, far ahead of competitive offerings.

“The introduction of these SIL certified transmitters is a great benefit to our clients. A Triconex safety instrumented system equipped with Foxboro transmitters can bring new efficiencies and savings in terms of system design, commissioning time and ongoing maintenance. The SIL 2 certification from TÜV Rheinland is also an advantage on its own because all clients in the safety automation market understand respect the stringent process required to attain this certification,” said Luis Duran, IPS Portfolio Marketing Director for Safety and Critical Control.
