profilhøjdemålere

Profilhøjdemålere, also known as profile projectors or shadow comparators, are optical instruments used for precise measurement and inspection of the profiles of small objects. They work by projecting a magnified, two-dimensional silhouette of the object onto a screen. This projected image allows for easy comparison against a master drawing or template, facilitating the detection of deviations and accurate measurement of dimensions such as diameters, angles, and contours.

The basic principle involves illuminating the object from behind or through a transparent surface, creating a shadow. This shadow is then magnified by a lens system and projected onto a viewing screen. Many profilhøjdemålere feature a work stage that can be moved in both horizontal and vertical directions, allowing for the measurement of various features of the object. The screen often has a grid or reference lines to aid in measurement and comparison.

These instruments are widely used in various industries, including manufacturing, quality control, and research and development, particularly for inspecting small, intricate parts like screws, gears, molds, and electronic components. They are valued for their non-contact measurement capabilities, which prevent damage to delicate workpieces, and their ability to provide highly accurate and repeatable results. Modern profilhøjdemålere may also incorporate digital readouts and data output capabilities for enhanced efficiency and record-keeping.
