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 metal and plastics testing, the precise recording of material deformation under load is essential in order to realistically assess the elongation and load-bearing capacity of materials. Manufacturers face the challenge of reliably analyzing the mechanical properties of new materials, especially when developing lightweight but resilient components for industrial use. Conventional measuring systems often reach their limits when it comes to microscopically small strains or fast load cycles.
Solution
By using high-resolution length gauges from NUMERIK JENA, a leading testing laboratory for materials technology was able to significantly improve its test procedures. The length gauges record strains with the highest precision and reproducibility, even with minimal deformations and under dynamic loads. Thanks to their optical scanning and robust design, the NUMERIK JENA length gauges are ideal for demanding test conditions.
