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 by the company that makes them), and it chose to compare them to potentiometer based sensors, and traditional magnetostrictive sensors. Notably absent were the family of modern draw-wire sensors made
