Heidenhain: Incremental Length Gauge METRO 331314-02 (MT1281)


Length gauges from HEIDENHAIN offer high accuracy over the entire measuring range, are mechanically rugged, and can be used in a great variety of applications.

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


Robust Design

HEIDENHAIN length gauges are built for an industrial environment. They feature consistently high accuracy over a long period of time as well as high thermal stability. They can therefore be used in production equipment and machines.


High Accuracy

The high accuracy specified for HEIDENHAIN length gauges applies over the entire measuring length. Whether the part measures 10 mm or 100 mm, its actual dimension is always measured with the same high quality. The high repeatability of HEIDENHAIN length gauges comes into play during comparative measurements, for example in series production.


Large Measuring Ranges

HEIDENHAIN length gauges are available with measuring ranges from 12 mm to 100 mm, so that you can measure very different parts in one measuring setup and avoid frequently changing setups with expensive gauge blocks or masters.
