  • Inductive proximity sensor
    Patent number: 9214937
    Abstract: An inductive proximity sensor and a method comprising a transmitter coil, a receiver coil, an excitation device which is connected to the transmitter coil and an evaluation device, wherein the evaluation device is designed to generate an output signal which depends on a voltage ratio between a transmission voltage of the transmitter coil and/or of the excitation device and a reception voltage of the receiver coil, wherein the excitation device is designed to generate a sinusoidal radio frequency transmission voltage. An inductive proximity sensor and a method comprising a transmitter coil, a receiver coil, an excitation device which is connected to the transmitter coil and an evaluation device, wherein the evaluation device is designed to generate an output signal which is dependent on a reception voltage of the receiver coil, wherein the excitation device is designed to generate a sinusoidal radio frequency transmission voltage with a constant amplitude.
