摘要：Measuring apparatus comprises a probe having a stylus supported on a housingby a spring extending in a plane transverse to the axis of the stylus and allowing thestylus to pivot about a center lying on the axis and to move linearly in the direction of theaxis. A sensor has fixed and movable parts off-set from the axis, the movable part beingconnected to the stylus by a transverse arm. The sensor senses both pivotal and axialmovement, the pivotal movement corresponding to movement of the work- contactingend of the stylus transverse to the axis. At least one further sensor is provided to senseat least the axial movement of the stylus. An electrical network responsive to bothsensor outputs is arranged to discriminate between transverse and axial movements ofthe stylus. Alternatively the sensors are arranged to give a single output for anymovement of the stylus.
