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… Continue reading The SL6000 Subsea Draw Wire Breaks the 100 Ft Barrier

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… Continue reading Heave Compensation Systems for Offshore Drilling

The CPI SL2000 Subsea Rated Linear Position Sensor

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… Continue reading Reinventing Draw Wire Sensors Part 1 – Mechanical Revolution

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: They are based on a sophisticated re-implementation of the draw-wire class of linear position measurement systems, proven in… Continue reading A New Angle On Linear Position Sensing
