摘要： The invention is directed to an electromagnetic holding device which includes one or more permanent magnets and an electromagnet. The holding device releases and pulls in units which are held thereon. During an exchange operation, the field of the electromagnet is superposable on the field of the permanent magnet either in the same direction or in the opposing direction and thereby intensifies or neutralizes the holding force. In order to provide the smallest possible assembly volume and lowest weight with the highest possible holding force, the permanent magnet is disposed ahead of the electromagnet when viewed with respect to the exchange face. When the exchange part is pulled in, the field lines of the electromagnet run in a completely closed flux-conducting part which is not interrupted at any location by an air gap.

摘要： The invention is directed to a temperature measuring head for rapidly measuring the temperature of a workpiece on a coordinate measuring apparatus. To rapidly measure the temperature of the workpiece, the coordinate measuring probe element is exchanged for a temperature measuring head which operates pursuant to the principle of a switching probe head. The measuring head supplies a contact signal after contact with the workpiece takes place. From this time point on, the temperature variation is measured by the temperature measuring head and the determined values are stored in the computer of the coordinate measuring apparatus. The temperature of the workpiece is extrapolated via a numerical evaluation method from a specific measurement interval. After the necessary measurement interval, the temperature measuring head is exchanged for the needed probe element combination. The invention is also directed to a temperature measuring head for carrying out the method of the invention.
