Actuator Feedback Systems
Actuator feedback systems provide closed-loop confirmation that a valve actuation has occurred — detecting end-of-travel position for both open and closed states, and supporting partial stroke test...
What This Application Involves
What Engineers Face in This Environment
Actuator feedback requires sensors that reliably distinguish between fully open, fully closed, and intermediate positions — under operating conditions that include hydrostatic pressure, vibration from flow, and thermal cycling. DepthLink's reed switch and Hall-effect sensor assemblies are specified with the actuation travel profile to ensure consistent switching at the correct position.
Safety-critical valves on production systems are increasingly required to demonstrate partial stroke capability without interrupting production. Feedback systems must resolve valve position to within a defined percentage of full travel. DepthLink can supply sensor assemblies with the resolution and linearity required to support partial stroke test regimes.
Actuator feedback signals must integrate cleanly with the subsea control module or surface SCADA system. DepthLink reviews the interface requirements — signal type, voltage levels, connector standard, and cable specification — before specifying, to ensure the delivered assembly connects without modification at either end.
