Abstract
A sensor device (4) detects a state of a lubricant. The sensor device (4) has a sensor unit (6). The sensor unit (6) is designed to measure the impedance of the lubricant according to the frequency of an applied alternating current. The sensor device (4) has an evaluation unit (8) which is designed to determine a state of the lubricant based on the measured impedance.
