The SL6000 Subsea Draw Wire Breaks the 100 Ft Barrier

Engineering Marvel - The CPI SL6000 30 Meter Hardened Linear Position Sensor

Since the introduction of our SL series hardened draw-wire Linear Position Sensors almost 20 years ago, we’ve learned a lot about long stroke hydraulics from our hydraulic cylinder manufactures. Our first sensor product


Heave Compensation Systems for Offshore Drilling

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


Motion Compensation System Hydraulics Can Get A Whole Lot Smarter.

The environment in which the search for oil is conducted beneath the surface of the seas is ever changing and often treacherous. It changes constantly due to the ebb and flow of the surface of the water and operation during inclement weather can be particularly


Reinventing Draw Wire Sensors Part 1 – Mechanical Revolution

We have to look at the CPI sensor as having two subsystems:  1.) The mechanical draw-wire mechanism which reduces the long travel of the draw wire to a highly accurate, directly proportional short stroke, and 2.) the electronics that very accurately track and transduce the


A New Angle On Linear Position Sensing

Those of you following our blog for the last few years, already know a few things about our linear position sensor products:

  1. They are based on a sophisticated re-implementation of the draw-wire class of linear position measurement systems, proven in thousands of applications over


The Expanding list of Harsh Duty Draw Wire Sensor applications

When CPI introduced its first version of a harsh duty draw wire sensor over a decade ago, it was because one of our large customers making construction vehicles needed something that would hold up better under harsh outdoor conditions and almost constant use. The sensor has
