One of the most popular limit switches CPI ever introduced has to be our J4 series waterproof limit switch. A small marvel of engineering originally developed for the military, this switch comes in both a ball switch and a plunger… Continue reading Breaking News: Quality and Affordability no longer Mutually Exclusive
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.
Last year we discussed CPI sensor solutions for Oilfield hydraulic accumulators and cylinders, but in the fast-paced world of oilfield engineering, that was a long time ago. For instance in 2016, CPI didn’t have a fully subsea capable (qualified to… Continue reading Marine Riser and Tensioner System Hydraulics – Revisited.
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
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.
In sub-sea applications used for mining oil and gas at the ocean floor, large and powerful hydraulic accumulators often get the job of providing emergency power on blow out preventers positioned on the sea floor. If you’re a hydraulic accumulator… Continue reading Hydraulic Accumulator Charge Sensing
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
One of the more challenging Hydraulic applications in the world exists far below the ocean, on the sea bed to be exact. A place where mother nature and the laws of entropy conspire to make all man made contraptions suffer,… Continue reading The Challenge of Subsea Position Sensing
For those of us engineering types who derive particular enjoyment from an understanding of how big machines work, one of the most awe inspiring things to understand is the power achievable through large scale hydraulic cylinders. Being a unique supplier… Continue reading Really Big Hydraulic Cylinders Are Cool…
