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.
