The “external simplicity” of the telescopic three-stage crossbeam that “hides” a precision mechanism inside (Patent WO2015/155621) is striking. Resting on two sliding carriages turning around the extruded bubble, it satisfies simultaneously and better than any other equivalent thickness measurement system the four basic requirements pursued by the designers: stiffness; absence of vibrations; a wide range of radial measures, minimum overall dimensions during rotation. No radial overhang; no intermediate junction between the carriages! Contact and No-Contact capacitive measuring sensors are available in the standard version. Other optional technologies (optical interferometry, multilayer, etc.) can be supplied upon request with prior feasibility assessment.

NEW NON CONTACT SENSOR for rotating Measurement Systems – No marks on Your film.
Sensor made of porous material generating a constant air cushion wich will keep a stable gap between bubble and sensor.
