Abstract

A measuring system monitors a spindle. The measuring system includes a cylindrical housing which can be arranged in and mechanically firmly connected to a spindle housing. A carrier ring is arranged inside the cylindrical housing. Three sensors for measuring a radial displacement and three sensors for measuring an axial displacement of the spindle are distributed over a circumference of the carrier ring. The sensors are cast with the carrier ring.
