Overview

The OptiMike optical micrometer provides direct, single-sided thickness measurement for non-metallic sheet and thick film products. The optical measurement technique is unaffected by the color, density, or gloss of the product. The sensor incorporates a light emitting diode (LED) array that projects a beam of light across the apex of the product wrapped over a precision reference roll. This roll has low run-out characteristics for accurate, absolute measurement performance. On the opposite side of the roll, a precision charged couple device (CCD) micrometer array measures the exact point of light beam interruption to determine the top surface of the product to sub-micron accuracy. An integrated eddy current sensor measures the distance of the sensor to the surface of the roll. The data from the CCD array and the eddy current sensor are combined to provide a total thickness measurement.

Overview

• Non-contact measurement.
• Non-nuclear gauge.
• Unaffected by product color, density, gloss, or transparency.
• Combine with weight sensor for density measurement.
• Intelligent gauge for ease of maintenance.
