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

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

The CPI SL2000 Subsea Rated Linear Position Sensor

CPI Announces Intrinsic Safety Rated Position Sensor

CPI Announces its newest member of the Subsea Linear Position Sensor family, the SL1490, CPI’s first fully ATEX & IEC-EX Intrinsic Safety rated sensor. As the first sensor of its type in the world, CPI has again raised the bar… Continue reading CPI Announces Intrinsic Safety Rated Position Sensor

Marine Riser and Tensioner System Hydraulics.

While CPI’s robust linear position sensor technology works great to report absolute cylinder position under the most demanding of conditions, it also has great application as a gauge of pre-charge pressure in a hydraulic accumulator. And perhaps nowhere is the… Continue reading Marine Riser and Tensioner System Hydraulics.

Draw Wire Sensors for Harsh Duty?

Here at CPI we’ve developed a name for ourselves when it comes to precision engineered draw wire sensors, made for harsh duty applications. Sensors like our SL1200 draw wire position sensor get the job when other sensors just don’t survive.… Continue reading Draw Wire Sensors for Harsh Duty?

Draw Wire Sensors Revisited

In ancient times when cave men were trying to measure the linear displacement of things they cleverly came up with something called a “String Pot”.  Using only stone knives and bearskins, they were able to cobble together a spool with… Continue reading Draw Wire Sensors Revisited

Draw Wire vs. Variable Inductance Position Sensors

A recent article in an EET Asia technology magazine discussed the advantages of linear position sensors based on variable inductance, as compared to those based on either magneto-strictive or potentiometer based sensors. The article was really a thinly veiled plug… Continue reading Draw Wire vs. Variable Inductance Position Sensors
