First Claim
1. A length measuring probe, comprising:
- a base body;
a guide element;
a probe pin comprising a touch scanning element for touch scanning a measuring object, said probe pin is guided, displaceable in relation to said base body along a measuring direction opposite a spring force F via said guide element;
a detection device that detects a position of said probe pin with respect to said base body;
a first spring element and a second spring element arranged behind said first spring element in said measuring direction so as to prestress said probe pin with said first spring element and said second spring element in a common direction; and

Abstract
A length measuring probe that includes a base body, a guide element and a probe pin having a touch scanning element for touch scanning a measuring object, the probe pin is seated, displaceable in relation to the base body in a measuring direction opposite a spring force F via the guide element. A detection device detects a position of the probe pin with respect to the base body and a first spring element and a second spring element arranged behind the first spring element in the measuring direction so as to prestress the probe pin. The guide element is arranged between the first and second spring elements, on which facing end areas of the first and second spring elements are fixed in place, and wherein the at least one guide element is seated, displaceable in the measuring direction, on the probe pin and on the base body.
