ABSTRACT:
A method for temperature compensation in measuring systems that are dependent on the operating temperature and whose temperature dependency is caused by temperature-sensitive components that can be operated electronically, or are linked thermally with a neighboring electronically driven component which is already required for the measuring system. In the method according to the invention, the temperature-sensitive component or a neighboring component are operated in such a way that temperature compensation can be performed without any further auxiliary means such as, for example, an additional heating device. Temperature compensation of this kind can then take place in three different ways. In the one method, the temperature coefficient determined and utilized; in a second method the temperature-sensitive components of the system are heated up to a fixed operating temperature, which is the basis for all measurements, and in a third method a temperature-independent operating point is determined.
