HEIDENHAIN Certo, Metro and Specto length gauges

HEIDENHAIN incremental length gauges offer high accuracy over long measuring ranges. They feature well thought out design characteristics in sturdily made models for industrial use.

They have a wide range of applications in production metrology, in multipoint inspection stations, measuring equipment and as position measuring devices.

The usual inspection of measuring equipment called for by standards, and the inspection of gauge blocks in particular, necessitates a large number of reference standard blocks if the comparative measurement is preformed using inductive length gauges. The problem is the small measuring range of this type of gauge as they can only measure differences of up to 10µm. Incremental length gauges, which offer large measuring ranges together with high accuracy, greatly simplify the calibration of measuring devices required to ensure traceability. The length gauges of the Heidenhain-Certo range with measuring lengths of 25mm to 60mm and accuracy of ± 0.1µm. This accuracy can be improved to ± 0.05µm after linear length-error compensation in the evaluation electronics, are well suited for this task. This permits a significant reduction in the required number of reference blocks and recalibrating becomes much simpler.

Multipoint inspection devices require durable length gauges with small dimensions. They should also have relatively large measuring ranges of several millimeters with consistent linear accuracy in order to simplify the construction of inspection devices. For example by enabling the construction of one device for several masters. Also a large measuring length provides benefits in master production, because simpler masters can be used.

With their smaller dimensions and measuring ranges of 12mm to 30mm and ± 1µm accuracy, the HEIDENHAIN-Specto incremental length gauges are specifically designed for multipoint inspection. Also unlike Inductive gauges,  the Specto length gauge provides a stable measurement over long periods eliminating recalibration. Higher accuracy requirements up to ± 0.2µm can be met with the similarly compact Heidenhain-Metro length gauges.
