Abstract :
This paper presents a Microelectromechanical systems (MEMS) solution to rotary valve position monitoring. With a device holding commercial off-the-shelf inertial sensors, we develop a sensing algorithm encompassing self-calibration, and noise and drift removal. Our repeatable results show an accuracy of ±5° for part-turn valves and ±10% of a turn for multi-turn models. Our small energy-efficient wireless solution is a cheap and reliable replacement for products on the market.
