The same diameter measuring techniques also allow ovality measurements.
Combining several diameter measuring instruments, in a biaxial, triaxial or quadriaxial configuration, makes it possible to obtain the ovality measurement. Systems with dynamic laser scanning are also available for determining the multi-section ovality profile.
Ovality measurement is one of the main metrological activities in industry. Ovality refers to the deviation from the ideal circular shape of an object and can have a significant impact on the functionality and quality of products. Ovality is measured using precision instruments such as laser gauges, comparators and laser distance sensors.
Laser gauges are a highly precise and reliable instrument used to measure ovality on tubes, shafts, round objects and other mechanical components. The precision of laser gauges makes it possible to detect even small deviations in the shape of the object, allowing any production defects to be identified. Laser gauges also allow fast and accurate measurements, reducing production time and costs.

Some applications of ovality measurement products
Technical insight
Ovality measurements are very important in various industrial sectors, such as aeronautics, automotive and precision mechanics. Several technologies are available for measuring ovality, each with its own characteristics and advantages. In this article we will explore six of these technologies: ovality measurement with vernier calipers, ovality measurement with industrial LASER distance sensors, ovality measurement with contact micrometers, ovality measurement with digital comparators, ovality measurement with laser micrometers and ovality measurement with bore gauges.
Ovality measurement with vernier calipers
Vernier calipers are very common measuring instruments and offer a fast and precise measurement of ovality. The ovality of external and internal surfaces can be measured with this instrument, thanks to their circular shape. The vernier caliper consists of a fixed part and a moving part fitted with measuring tips, which can be replaced according to measuring requirements. With vernier calipers, a precision of ± 0.01 mm can be obtained.
Ovality measurement with industrial LASER distance sensors
Industrial LASER distance sensors are measuring technologies that use a beam of LASER light to measure the distance between two points. These instruments can be used to measure ovality by means of an optical technique. The laser distance sensor projects a laser spot onto a surface and measures its distance. By repeating this operation at several points on the surface, a three-dimensional map of the oval can be obtained, making it possible to identify the most critical points. The precision of an industrial LASER distance sensor can reach ± 0.1 mm.
Ovality measurement with contact micrometers
The contact micrometer is a mechanical measuring instrument that allows the dimensions of metal surfaces to be measured with great precision. It can be used to measure the ovality of an object, with a precision of ± 0.001 mm. The contact micrometer works by positioning the contact surface between the object and the micrometer probe, which is then locked, and the measurement is read on the built-in display.
Ovality measurement with digital comparators
The digital comparator is an electronic measuring instrument that allows variations in the dimensions of an object to be compared with a reference value. It can be used to measure the ovality of an object by positioning the comparator on the internal or external surface of the object. The digital comparator is a very precise instrument, with a precision that can reach ± 0.001 mm.
Ovality measurement with laser micrometers
The laser micrometer is a measuring instrument that uses a laser beam to measure the distance between two points. The laser emits a beam of light that is made to interfere with the object, producing a shadow projection. This measuring system makes it possible to obtain very high precision, which can reach ± 0.001 mm. The laser micrometer can be used to measure the ovality of an object by performing several scans of the surface.
