This new gauge option for the ISIS Dimensional Gauge is an integral part of its MiniLab Glass Container Measurement System. This new option provides the ability for automated mold-correlated wall thickness measurement of glass containers on a sampling basis. The wall Thickness Gauge uses a single non-contact chromatic sensor with a 10um spot size to measure the wall thickness of glass containers from 1 to 10mm with a repeatability of +/-0.15mm. A servo-controlled linear slide automatically keeps the chromatic sensor at optimal distance from the surface of round and non-round containers during the entire measurement sequence. Once installed and calibrated, the Wall Thickness Gauge does not require any mechanical adjustment. When creating a job, the operator simply specifies the distance from the top of base of the container the different wall thickness measurements should be performed. Up to nine locations can be specified, each with different diameter and min/max limit values. The ISIS elevator automatically positions the container in front of the sensor at the specified locations. The wall thickness is measured 360 degrees around the container at each location. The Wall Thickness Gauge is available as an option on new ISIS machines and as a field upgrade for any machine already in operation.
