Preform Thickness Gauge

High precision measurement for determining material concentricity and distribution of PET preforms

The Preform Thickness Gauge provides automatic measuring for material thickness and concentricity of PET and PET/PEN preforms. The measurement cell is equipped with four ultrasonic sensors and a universal preform fixture. This ultrasonic measuring instrument provides precise, repeatable and reproducible thickness measurement over a cross section of the preform.

Easily detect core shift and bent cores

Eliminate the need for elaborate fixturing
