Woodward 1886-7003
Product Overview
A high-temperature, variable reluctance magnetic pickup (MPU) sensor designed for detecting rotational speed of industrial diesel/gas engines and turbines. It generates a robust AC voltage signal proportional to the speed of a ferromagnetic gear or toothed wheel, ensuring reliable operation in extreme temperature and high-vibration environments.
