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

Draw Wire vs. Variable Inductance Position Sensors

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 for variable inductance sensors (written
