Rig & Mast Raiser Hydraulics
Hydraulic Position Sensing for Oil & Gas Recovery Applications Hydraulic cylinders deployed into drilling platforms such as land-based mast raiser systems are used for oil and gas recovery in a wide variety of fixed and mobile configurations. The hydraulic cylinders… Continue reading Rig & Mast Raiser Hydraulics
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
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
Reinventing Draw-Wire Sensors – Introduction
Perhaps one of the most memorable moments of my career at CPI happened over a decade ago, when CPI was first asked to produce a robust hydraulic position sensor for a large well known maker of construction vehicles and equipment. In… Continue reading Reinventing Draw-Wire Sensors – Introduction
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 Expanding list of Harsh Duty Draw Wire Sensor applications
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
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
