First select a product category. Here you can choose between linear encoders, angle encoders or length gauges.
Select the accuracy of the incremental length gauge that meets your requirements. You can choose between two accuracy classes, SPECTO for ±1 µm or METRO for ±0.5 µm.
The position detection can be incremental or absolute. The incremental measuring method provides a relative position as well as direction of movement, which requires an assignment to a reference point (starting point) at the beginning of the measurement. This is done by homing the axis. The absolute measuring method provides concrete position information at any axis position. A reference run at the beginning of the measurement is not necessary.
At this point you can select the type of bolt actuation. You can choose between two variants, spring-driven or pneumatic. With spring-driven length gauges, the built-in spring extends the measuring bolt into the measuring position and builds up the measuring force. The measuring bolt is extended in the rest position. On length gauges with pneumatic bolt actuation, the bolt extends when compressed air is applied. When the compressed air connection is vented, the built-in spring retracts the measuring bolt.

The challenge
In the industrial production of machine components, the precise measurement of components is a critical step in ensuring product quality. Particularly when machining on straightening benches, fast and accurate acquisition of many measuring points is required in order to detect and correct deformations immediately. Manual measuring methods quickly reach their limits here - both in terms of speed and reproducibility.
Solution
A leading mechanical engineering manufacturer integrated the high-precision length gauges from NUMERIK JENA into its automated straightening benches. Several length gauges in combination enable extremely accurate real-time measurements of neighboring measuring points and provide an optimal database for efficient evaluation. The slim design of the length gauges and the resulting particularly small baying dimensions increase flexibility in the selection of measuring points. Thanks to their immediate readiness for use and high measuring accuracy over the entire measuring length, NUMERIK JENA length gauges significantly reduce the process times and susceptibility to errors of the measuring setups. The data obtained is used directly to control the correction mechanism - without any manual intervention.
The result
Conclusion
The integration of NUMERIK JENA length gauges in automated straightening benches is revolutionizing component measurement in mechanical engineering. The combination of real-time data, high measuring accuracy and automated correction provides a new dimension in efficiency and quality - a clear competitive advantage for manufacturers who rely on future-proof production technologies.
The new platform design offers many advantages for users in a wide range of (metrology) applications such as quality assurance or production metrology.
