Abstract
An inductive sensor (10) has a substrate (20), on which multiple transmitter/receiver coils (31, 32, 33) are arranged side by side. It can be operated in such a way that the transmitter/receiver coils (31, 32, 33) are each stimulated independently of one another at a frequency of more than 100 MHz.
Claims19
An inductive sensor, comprising:
- a substrate on which multiple transmitter and receiver coils are arranged side by side;
- a printed circuit board connected to the substrate;
- multiple measuring elements coupled to the multiple transmitter and receiver coils for measuring frequency and amplitude values:
- a computing device that is a microcontroller arranged on the circuit board;
- and
- a temperature sensor integrated into the computing device;
- wherein each transmitter and receiver coil has 1 to 4 windings;
- wherein, measured frequency and amplitude values are calculated taking into account data from the temperature sensor.
