Its interesting to look at sensor manufacturer’s talk about the “long stroke” version of their hydraulic position sensors. They go on about how their amazing sensors can actually operate on stroke lengths of up to 1.2 meters in some cases! These sensors constitute a variety

When CPI introduced its first harsh duty hydraulic cylinder linear position sensors over a decade ago, we designed them to be as compact as possible, primarily for installation into hydraulic cylinders. Some of our customers wanted them to work

As oilfield engineering enjoys a resurgence of interest and investment, companies continue to look to advancements in technology to both reduce costs, and improve the safety of offshore drilling operations. In particular, active heave compensation systems use advanced hydraulic cylinders and accumulators to achieve a

For well over a decade, CPI has been manufacturing a unique Hydraulic Cylinder Linear Position sensor, meant for the harshest environments, and longest stroke applications on the planet. We’ve learned a lot over that decade. We’ve not only improved the accuracy and durability of

Two important considerations when looking at the integration of any hydraulic linear position sensor are the underlying technology and the packaging of the transducer. These principles effect size, life, maintainability, and above all, durability. The underlying technology used influences the linearity, repeatability, resolution, temperature immunity, maximum
Read More...Interestingly when one looks back at the history of hydraulic position sensing technology some of the earliest ideas from as far back as the 1950’s revolved around both potentiometer based implementations and draw wire systems. Potentiometer based systems with their friction based wiper technology

Mining and earth-moving operations around the globe have inspired some of the largest, most powerful machines ever designed and built by man. These machines involve millions of parts and sub-assemblies and can weigh on the order of close to 500,000 tons. They are designed to

Last year we discussed CPI sensor solutions for Oilfield hydraulic accumulators and cylinders, but in the fast-paced world of oilfield engineering, that was a long time ago. For instance in 2016, CPI didn’t have a fully subsea capable (qualified to 5000ft), intrinsic

If you’ve spent more than 5 seconds perusing the CPI Website, then you know that toughness and durability are the primary attributes of everything we make. Nowhere is this more apparent than in our newest SL2000MS, our hybrid design, long stroke linear position
