Abstract
A device for determining moisture has an LC-oscillating circuit as a transducer and an oscillator for exciting the oscillating circuit. Further, the device for determining moisture has a tuning device for frequency-wise tuning the oscillator and a measuring and evaluation circuit to determine an attenuation condition of the oscillator and to provide a signal that is proportional to a degree of moisture at the transducer. The transducer and the oscillator are coupled in a contact-free manner.
