Proof Testing of Safety Instrumented Systems
Optimize proof testing with smart technologies and services for sustained safety and availability
Proof testing Safety Instrumented Systems (SIS) has become a key challenge for the worldwide chemical industry. Such systems are increasingly commonplace for compliance or performance purposes and require regular testing to ensure alignment to standards and processes. Faced with tough competition and reduced margins, the problem for plant operators becomes how to optimize testing methods to ensure costly downtime is minimized, and to do so with the benefit of full, in-depth diagnostic coverage.
