Fieldvue® DVC6000 enhancements

Emerson Process Management has announced enhancements to its SIL 3 certified Fisher® Fieldvue® DVC6000 digital valve controller for Safety Instrumented Systems (SIS). The enhancements help improve reliability, flexibility, and availability of Emergency Shutdown (ESD) valve solutions. The ESD final control system components are integrated with safety-certified sensors and SIL3 rated systems in Emerson’s digital smart SIS solutions. The DVC6000 SIS instrument enhancements include manual reset, a stored safety demand event log, pass / fail status after a partial stroke test, and third party certification to SIL3, SIF loop. A safety demand event can be stored in the non-volatile memory of the microprocessor and retrieved at any time. This event log is critical for plant personnel, reliability engineers, and auditing authority to properly understand the final element status before and after the trip or demand event. After the completion of a partial stroke test, the DVC6000 SIS instrument will provide a pass or fail status along with a signature curve. It will also provide additional diagnostics on stick slip, shaft integrity, and maximum and minimum torque. The instrument is also available in stainless steel constructions for harsh offshore environments and severe service constructions.
