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
When CPI introduced its first version of a harsh duty draw wire sensor over a decade ago, it was because one of our large customers making construction vehicles needed something that would hold up better under harsh outdoor conditions and… Continue reading The Expanding list of Harsh Duty Draw Wire Sensor applications
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
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
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
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
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
