Cost-effective alternative to
positioners for SIS
For the networking, monitoring and control of process valves, Westlock Controls has announced the D-EPIC Control Transmitter, a cost-effective alternative to positioners for SIS applications
Westlock Controls, a leader in providing innovative solutions for the networking, monitoring and control of process valves, has announced the introduction of the D-EPIC Control Transmitter This 4-20 mA, HART-enabled, non-contact transmitter eliminates position blind spots during the stroke of a valve by supplying continuous feedback of either rotary or linear valve position

The D-EPIC control transmitter features an integrated, low power solenoid used to control and monitor discrete valves, as well as integrated PST functionality.
The device provides a cost-effective alternative to positioners for Safety Instrumented System (SIS) applications.
Exida confirmed the D-EPIC is suitable for Safety Integrity Level 3 (SIL3) service by performing a FMEDA with calculated PFD and SFF values.
Unlike conventional position transmitters, the D-EPIC senses valve position without the need for linkages, levers, or rotary and linear seals.
Position sensing is performed by non-contact means via the use of an integrated Hall Effect sensor and magnet assembly.
This also allows a remote sensor head assembly to be mounted up to 50 feet from the electronics enclosure.
Available in low copper content aluminium, 316 stainless steel or engineered resin enclosures, the D-EPIC is agency certified for non-incendive CID2 Groups A-G service and explosion-proof CID1 Groups B-D service with the MOD3 or 360/366 enclosures.
The D-EPIC Control Transmitter is easy to set up, and calibration is via a local, non-intrusive interface and integrated LCD display or HART communicator.
