Today’s petrochemical and process industries, like most industries, are striving to increase their capabilities of automation & control, coupled with condition monitoring, across their entire operation. Demands for uptime are increasing and the focus on reliability through redundancy and prediction of pending maintenance requires new control and monitoring strategies. This is nowhere more true than in the case of the sophisticated valves that form the most critical elements of the operation or process. Operational readiness and confirmation of operation for these valves are indispensable to assure smoother and uninterrupted production…and safety.
Christian Dow has written an interesting article in Valve Magazine that highlights the benefits of linear position sensors when installed in the hydraulic actuators of these valves. The benefits mentioned in the article don’t apply just for valves, though. Many of the advantages can be obtained for almost any application where a hydraulic cylinder is the prime mover.
