Length gauge measures in harsh environments

Heidenhain has introduced the Specto ST 3087 RC length gauge, designed for measurement applications in harsh environments, such as metal cutting production areas. Its IP67-level ingress protection allows parts to be measured directly at the grinding, cutting, or forming location.

The gauge has a special housing for in-process measurements. In the plunger rest position, it houses the plunger and a rubber bellows surrounding the plunger, as well as a splash guard cap to close the exit opening for the plunger in the housing. For a measurement, which is normally made when the cooling lubricant is switched off, only the plunger and its bellows extend out of the housing, driven by compressed air.
