Linear Displacement Transducer, 400mm V

M-Series Linear Displacement Transducers

Linear displacement transducers provide accurate, reliable, absolute position feedback to help automate machinery. The M-Series displacement transducers are an ideal alternative to traditional potentiometers as they are accurate, programmable non contact position sensors in a low profile package, that use magnetostrictive technology to give absolute analogue feedback.

Linear Variable Differential Transformers (LVDT)

These devices comprise a movable nickel iron core and three coils - one for energisation and two for pick-up. They need to be driven by a sine wave to produce an output amplitude and phase directly proportional to the position of the core with respect to the pick-up coils. A phase sensitive detector is required to demodulate the output signal. The main advantages of LVDTs are;
