Two important considerations when looking at the integration of any hydraulic linear position sensor are the underlying technology and the packaging of the transducer. These principles effect size, life, maintainability, and above all, durability. The underlying technology used influences the linearity, repeatability, resolution, temperature immunity, maximum

Interestingly when one looks back at the history of hydraulic position sensing technology some of the earliest ideas from as far back as the 1950’s revolved around both potentiometer based implementations and draw wire systems.  Potentiometer based systems with their friction based wiper technology
