Apparatus for detecting the temperature of an object on a coordinate measuring apparatus
First Claim
1. In a coordinate measuring apparatus having a movable measuring arm for moving and releasably engaging a plurality of coordinate measuring sensor components, each of the coordinate measuring sensor components having a holder which enables the coordinate measuring sensor components to be exchanged one for the other, a temperature sensor component for measuring the temperature of an object being measured by said coordinate measuring apparatus, the temperature sensor component comprising:
- a temperature sensor holder having a form corresponding to the form of the holder of each of said coordinate measuring sensor components, whereby said temperature sensor component is exchanged with one of said coordinate measuring sensor components to measure the temperature of the object.

Abstract
An apparatus for detecting temperature of an object to be measured such as a workpiece mounted on a coordinate measuring apparatus having a movable measuring arm. The measuring apparatus includes a sensing pin or complete sensing head as well as a temperature sensor. For measuring temperature, the sensing pin or sensing head is exchange for the temperature sensor having the same kind of holder as the sensing pin. Thereafter, the temperature sensor is moved to the object by the measuring arm of the apparatus and is placed in contact therewith. The registered temperature measurement values are used to correct the lengths and spacings measured with the coordinate measuring apparatus. The entire temperature and coordinate measuring operation is carried out completely automatically by the CNC control of the apparatus without the aid of operating personnel. A temperature sensor for carrying out the method of the invention is also disclosed.
