Abstract
A sensor device determines an alternating voltage between a conductor and a reference potential, particularly of a switch point drive. In order to reduce the installation cost and effort required to verify the absence of reaction, the sensor device has a sensor element, which is configured for capacitive coupling to the conductor, and a resistance element, which is provided for connection to the reference potential and is connected in series together with the sensor element. The sensor device further has a processing device, which is configured to determine a voltage drop via the resistance element.
