Woodward 3458-016

Product Overview

A high-sensitivity variable reluctance magnetic pickup (MPU) sensor designed for detecting rotational speed of engines, turbines, and generators. It generates a strong AC voltage signal proportional to the speed of a ferromagnetic gear or toothed wheel, ensuring reliable low-speed detection in harsh industrial environments.
