Abstract:
Method for temperature compensation of an LC oscillator (8) having a machining head (4) and serving for the capacitive measurement of a distance between the machining head (4) and a workpiece (7), in which an output signal (S) of the LC oscillator (8) is transmitted to an evaluation unit (2) arranged separately from the machining head (4), characterized in thatthe temperature (T) of the LC oscillator (8) is measured with the aid of a temperature sensor (29), the temperature (T) is transmitted to the evaluation unit (2), and in the evaluation unit (2), temperature compensation of the output signal (S) of the LC oscillator (8) is effected using the measured temperature (T) and a temperature coefficient (K) assigned to the machining head (4).
