Evaluation method for an inductive displacement sensor

A method for determining a temperature-compensated measured value and for calibration of a displacement sensor designed as an inductive displacement sensor, comprising:

• measuring at least one of the displacement sensor temperature and an environmental temperature thereof to obtain a measured temperature at a time of measuring;
• determining a measured sensor value applicable at said measured temperature;
• determining a temperature coefficient which is at first unknown by using a first function and a second function, the first function being based on the temperature-dependency of the measured sensor value, and the second function being based on the known dependency of the sensor temperature coefficient on the measured sensor value at a reference temperature, wherein the dependency of the temperature coefficient is based on a particular sensor model, said step of determining including solving the two functions using iteration;
• temperature-compensating the measured sensor value to form a temperature-compensated measured sensor value by converting the measured sensor value into the measured sensor value applicable at the reference temperature using the temperature coefficient applicable to the sensor and the temperature difference between the measured temperature and the reference temperature;
• and
• converting said temperature-compensated measured sensor value into a measured value with a mechanical length unit through calibration.
