PreciLogger - Non Contact Thickness Measurement

PreciLogger - Non Contact Thickness Measurement

Overview

PreciLogger is an in-process non-contact width or thickness measuring system. Being non-contact it is suitable for measuring soft or fast moving materials that would be otherwise impossible to measure with normal contact methods. PreciLogger is a stand alone system which continuously monitors the production process providing 100% product inspection. The system provides the operator with a clear display showing the measured dimensions and trend graph, alarms will warn if the measurement exceeds tolerance limits. In addition production statistics are compiled for a complete batch and are displayed or printed on request. All the measurement data is archived and can be accessed later for quality assurance purposes.

Operating Principle

The thickness (or width) is measured by a pair of PreciCura SR or MR sensors which use the principle of optical laser triangulation and measure directly to almost any material or surface. They are connected together in differential thickness mode.
