Applications:

Displacement and Position Measurement

Magnetostrictive Linear Displacement Transducer. The MagneRule Plus™ magnetostrictive linear displacement transducer provides highly accurate absolute position measurement of displacement up to 120 inches (3 meters). The sensor also measures velocity, giving feedback of both position and velocity simultaneously. Operation is based on accurately measuring the distance from a predetermined point to a magnetic field produced by a movable permanent magnet. The design and durability of the sensor make it ideal for measuring position of moving machine members.
