Frequency Response Modeling of Inductive Position Sensor with Finite Element Tools
Position sensors have several applications in the automotive sector. Some of the common examples include automatic gear shifter module, seat position adjustment and accelerator-pedal position modules etc. Because of extreme weather condition, such as dust, humidity and moisture and fluctuation of temperature and wide operating temperature range. A non-contact type of inductive position sensor has several advantages in such applications. The paper presents a frequency response modeling of planar spiral inductive coils printed directly on the PCB and can be used as a non-contact inductive position sensor.
