Have you Looked At CPI Linear Position Sensors Lately?

For well over a decade, CPI has been manufacturing a unique Hydraulic Cylinder Linear Position sensor, meant for the harshest environments, and longest stroke applications on the planet. We’ve learned a lot over that decade. We’ve not only improved the accuracy and durability of

CPI Internal Draw Wire Position Sensors Replace External Sensors in Oilfield Mast Raiser System.

If you’ve spent more than 5 seconds perusing the CPI Website, then you know that toughness and durability are the primary attributes of everything we make. Nowhere is this more apparent than in our newest SL2000MS, our hybrid design, long stroke linear position

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 accurately track and transduce the

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:

  1. They are based on a sophisticated re-implementation of the draw-wire class of linear position measurement systems, proven in thousands of applications over

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 almost constant use. The sensor has

Linear Position Sensors for High Temperature Environments

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 applications, when you need to

Linear Position Sensors for Harsh Environments

For many years, hydraulic cylinder manufacturers were forced to forgo accurate, robust hydraulic cylinder position measurement on the largest, most powerful hydraulic systems: you know, the place where it’s needed most? Since these systems are typically operating outdoors, under extremely high pressure, vibration, and temperatures, existing

Magnetostrictive Position Sensor Replacement – Part II

As mentioned in our last post Magnetostrictive Linear Position Sensors are a common type of position sensor for hydraulic cylinders where high resolution is of primary concern.  The sensor incorporates a stainless steel tubular probe (ie. “the Rod”) and is surrounded by a short toroidal
