In this paper a method for dimensioning of inductive spring sensors is shown. This is done using an example of seat occupancy detection sensor of the automotive industry. It is in this case deals with the calculation of the individual components of the spring sensor. Thereby the crucial part for this is the calculation of the inductance of the spring sensor, because the components of the signal processing must be designed for them. Furthermore, it is shown how the example of the seat occupancy detection sensor, the analogue measurement signal is generated and can be calculated. The results of the development of the seat occupancy detection sensor are presented. This method can be used to design any other inductive spring sensors. This offers the advantage that a cost-effective development of spring sensors is possible, because they can be dimensioned theoretical first.
