IMI has launched a new high-performance digital pneumatic positioner for use in safety instrumented systems (SIS) to provide reliable safety functions for blowdown and emergency shutdown valve actuation in critical applications.
With a patented algorithm and high output CV that delivers ultra-fast stroking times for enhanced safety performance, the SHP-SIS Safety Smart High-Performance Positioner works within pneumatic operating pressures of 150 PSI (2.5 to 10.5 bar) and ambient temperatures between -67 to 186°F (-55 to 85°C). The SHP-SIS’s built-in partial stroke testing (PST) and SOV diagnostic capabilities ensure compliance with functional safety requirements and assist in supporting preventative maintenance practices.
The positioner is designed with the ability to create a digital twin within the control system. This allows for faster online swap-overs during service periods, alongside online data monitoring and advanced online and offline diagnostics capabilities. Its digital twin technology also enables smart commissioning for faster set-up, with a complete digital inventory of valve configuration and performance history.
The SHP-SIS is available in low copper aluminum housing or 316 stainless steel and a painted option for harsh operating conditions. Its robust design includes a contactless travel sensor and tough touchscreen interface, with fully encapsulated electronics tested for high vibration and reliability. It is TUV-certified for SIS applications and is certified according to IEC 61508:2010 up to SIL 3.
