Miniature Gage Head

GH-SM series LVDT

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

Several options are available for signal conditioning: the model EL-15 signal conditioner, model CB-100 line powered control box, and the USB-10 digital controller.
