Glossary

All Werth coordinate measuring systems with optics, probe, computed tomography and multi-sensor systems are manufactured at our headquarters in Giessen. You can gain an insight into the manufacturing process during the company tour as part of the Werth Technology Day in Giessen in the autumn.

Measurement involves determining a value for a physical quantity by comparison with a unit.

Systems and methods for the measurement of physical quantities and the testing of the correspondence between target and actual conditions, as well as their development and application

Measuring equipment is machinery for measurement or analysis, e.g. manual bench gauges or coordinate measuring systems.

Colloquial term for coordinate measuring machine, usually only referring to machines with tactile sensors

Optical 2D coordinate measuring machine with microscope and X-Y stage. The operator sights the points of the object to be measured with an optical crosshair and, in the simplest case, reads off the coordinates from the scales of the measuring table. The principle is the forefather of all coordinate measuring machines. A workshop measuring microscope is a measuring microscope designed for use in the manufacturing environment.

With profile projectors, the image of a 2D workpiece is projected onto a ground-glass screen with the aid of lenses and mirrors and compared there with a usually transparent drawing. Similar to a measuring microscope, measuring projectors also allow the measurement points at the edge transitions to be determined, for example with the help of a crosshair or optical sensors.

A measuring system is used for the measurement of physical quantities.

Metrology is about measuring equipment and procedures for the measurement of physical quantities as well as their development and application.

Probes for coordinate measuring systems with probe tips ranging in size from a few 10 micrometres to a few 100 micrometres (much smaller than 1 mm), enabling the measurement of small geometries and delicate workpieces, often with low probing force. These are used both in tactile, but more often in multi-sensor coordinate measuring machines because they are easier to operate.

A multi-sensor enables measurements with different sensor principles using the same hardware. For example, an optical distance sensor can be integrated into the image processing beam path.

Coordinate measuring systems and associated methods that serve to determine and subsequently mathematically evaluate the spatial coordinates of individual points, as well as their development and application. Multi-sensor coordinate metrology includes all coordinate metrology systems equipped with different sensor principles

The combination of different sensor principles, often both non-contact and contact, enables the solution of a large number of industrial tasks.
