Abstract
A dimension-measuring probe for fine measurements having a probe lever pivoted between its ends to provide an indicator arm and a sensing arm on opposite sides of the pivot. The sensing arm terminates in a pivot point. Spring means separate from the probe lever is provided next to the probe lever and connects to the probe point. The spring means serves to urge the probe point into contact with a work piece being measured. This structure eliminates stress on the sensing arm which tends to bend the arm and cause errors in measurement.
