High speed laser micrometer measures circumference, diameter and ovality of cylindrical objects

A manufacturer of inspection equipment has applied a high speed, non-contact laser micrometer to measure the circumference, diameter and ovality of cylindrical objects, including cigarettes, filters and cigars. The company is also utilising the same sensor to measure the shape of shoulders for extruded laminate tubes.

Cerulean, based in Milton Keynes, designs and manufactures a range of quality assurance systems and instrumentation for applications in analytical laboratories and manufacturing processes of cigarette and filter rod producers.

Cerulean’s CD Express is a bench top instrument that measures and displays the circumference, diameter and ovality of cylindrically shaped objects. At the heart of the CD Express is a non-contact laser micrometer, supplied by precision sensor manufacturer Micro-Epsilon UK Ltd. 

Micro-Epsilon’s optoCONTROL ODC 2500-35 sensor is a non-contact, laser-based measurement system with an integral, high resolution CCD camera for measurement of dimensions. The sensor offers high sampling rates, outstanding accuracy and excellent resolution. As Steve Frankham, Sales & Marketing Director at Cerulean states: “We selected the Micro-Epsilon sensor for its robustness and ease of use; particularly the fact that it could be easily configured to fit the required application.”
