Remotely proof-testing to improve SIS performance

(22/01/2019)
Periodic proof-tests are a necessity for level switches that form part of a safety instrumented system (SIS) and partial proof-tests provide a safe way to optimise the time interval between full tests. Marianne Williams compares different ways of performing partial proof-tests.
