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 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… Continue reading Motion Compensation System Hydraulics Can Get A Whole Lot Smarter.
Systems like municipal water supplies, sewage treatment plants, massive cooling and lubrication systems used in chemical, petrochemical, and the oil and gas industry, all share one thing in common: large flow valves that are critically opened and closed by computer… Continue reading Valve Position Sensing for Mission Critical Flow Applications.
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
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
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.
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?
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
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
As anyone in the industry will tell you, the technology for exploration and retrieval of Oil or Natural Gas harnesses some of the most powerful and unique engineering machinery in the world. Both the scale and scope of this equipment… Continue reading Oil & Gas Industry Offshore Drilling Equipment – The Definition of Toughness.
