Abstract
The solid-state oscillator, preferably a watch crystal (1/2), is mounted with its direction (S) of vibration at an angle to all three measuring directions (x, y, z) of the coordinate measuring apparatus. The oscillator circuit of the solid-state oscillator is connected to an electronic circuit which generates two different contact signals. Both measures make it possible to reduce the dependency of the contact uncertainty of the measuring direction.
Claims6
A coordinate measuring apparatus defining three measuring directions (x, y, z), the apparatus comprising:
- a solid-state oscillator having a direction (S) of vibration;
- a thin rod defining a probe element and being mounted on said solid-state oscillator;
- and,
- said solid-state oscillator being mounted relative to said three measuring directions so as to cause said direction (S) of vibration to be at an angle to all three of said measuring directions, so that said direction (S) of vibration is inclined to all three of said measuring directions.
