Miniature Gage Head GH-SM series LVDT

This micro-miniature spring-loaded LVDT is designed for high resolution position measurement in tight places. It is layer wound on metal coilform provides excellent stability, while ferromagnetic housing takes care of the electromagnetic and electrostatic shielding.

Several options are available for signal conditioning: digital or analog EL-35 signal conditioners and USB-10 or USB-10-4 digital controllers, manufactured by Singer Instruments & Control.

Applications

robotic systems - micro motion measurement;
civil engineering - movements and deflections;
optical components - linear/angular position;
medical use - micro motion, deformation.
