The invention relates to a transmitter device (2) for a sensor device (1) for sensing a magnetic field change caused by an object approaching or moving past the sensor device (1), in particular by a wheel of a rail vehicle, wherein the transmitter device (2) has at least two alternating-current-fed transmitter oscillating circuits (5.1, 5.2). According to the invention, in order to implement error disclosure of the sensor device (1) in a particularly simple manner, the at least two transmitter oscillating circuits (5.1, 5.2) are designed in such a way that the resonance frequencies (f
