VMS808/VMS811/ VMS818/ VMS825 eddy current sensor

overview

Used to measure the dynamic and static displacement of an object relative to the mounting structure. It uses non-contact measurement, and its components include: non-contact sensor, extension cable, and front end (all three parts are the same).
