New OptiMike from NDC Infrared Engineering, Irwindale, Calif., was developed to meet the need for accurate but cost-effective measurement of thicker and foamed sheet that would otherwise require nuclear gauges. Measuring across the crown of a roller, OptiMike measures the shadow cast on detectors from an array of LEDs, while an integral eddy-current sensor measures the proximity of the roller surface to calculate the exact caliper thickness of the product, without influence from the product density. OptiMike also offers an economic advantage through its single-sided configuration, reducing hardware requirements and easing installation.
