Abstract
The invention relates to a method for temperature compensation of an LC oscillator ( ) having a machining head ( ) and serving for the capacitive measurement of a distance between the machining head ( ) and a workpiece ( ), in which an output signal (S) of the LC oscillator ( ) is transmitted to an evaluation unit ( ) arranged separately from the machining head ( ). The temperature (T) of the LC oscillator ( ) is measured with the aid of the temperature sensor ( ) and supplied to the evaluation unit ( ). In the evaluation unit ( ), temperature compensation of the output signal (S) of the LC oscillator ( ) is effected using the measured temperature (T) and a temperature coefficient (K) which is assigned to the machining head ( ) and can likewise be transmitted from the machining head ( ) to the evaluation unit ( ).
