A transmitter device for a sensor device detects a magnetic field change caused by an object approaching or moving past the sensor device, in particular by a wheel of a rail vehicle. The transmitter device has at least two alternating-current-fed transmitter oscillating circuits. In order to implement error disclosure of the sensor device in a particularly simple manner, the at least two transmitter oscillating circuits are formed in such a way that the resonance frequencies thereof are different from each other. A sensor device and a method for detecting a magnetic field change are also provided.
