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

Have you Looked At CPI Linear Position Sensors Lately?

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… Continue reading Have you Looked At CPI Linear Position Sensors Lately?

The CPI SL2000 Subsea Rated Linear Position Sensor

What Can I Do with My Intrinsic Safety Rated Position Sensor?

Well that’s a fine question indeed! And the answer, like the answer to many interesting new technologies, is that it depends mostly on your imagination, and your budget!  Here’s just a few of the applications we’ve already been either designed… Continue reading What Can I Do with My Intrinsic Safety Rated Position Sensor?

Reinventing Draw Wire Sensors – Part 2

Draw Wire Sensor Measurement Electronics In our first segment on reinventing draw wire sensors, we discussed the tremendous amount of mechanical design and materials science innovation that went into the creation of an entirely new, high endurance draw wire position… Continue reading Reinventing Draw Wire Sensors – Part 2

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

Linear Position Sensors for High Temperature Environments

Traditional Linear Position Sensor technologies (ie. Magnetostrictive sensors) used in hydraulic cylinders have been limited in their ability to function in high temperature environments. One of the strongest applications for CPI SL series sensors are in these high temperature hydraulics… Continue reading Linear Position Sensors for High Temperature Environments

Linear Position Sensors for Harsh Environments

For many years, hydraulic cylinder manufacturers were forced to forgo accurate, robust hydraulic cylinder position measurement on the largest, most powerful hydraulic systems: you know, the place where it’s needed most? Since these systems are typically operating outdoors, under extremely… Continue reading Linear Position Sensors for Harsh Environments
