Linear Position Sensor Technology Choices

There are a number of technologies to choose from when considering the implementation of a linear position sensor.  As CPI's own sensors focus on the needs of hydraulic cylinder and hydraulic accumulator designers, it is instructive to review the various technologies being used in this market and the relative tradeoff's of each, as compared to CPI's LVDT based Linear Position Sensors.
