A sensor device () detects flowable media ('), in particular fluids () received in pressure devices (), such as pressure containers () or pressure lines. A sensor element () has an oscillation device () that is excited to produce oscillations under the action of a field () of a field generation device (). The oscillating behavior of the oscillations changes upon inflow of the respective medium (). The changes can be detected by a measuring device ().

Sensor device for detecting flowable media, a pressure device and a measuring method

A media separating device (), in particular a hydraulic accumulator (), has a movable separator () separating two media () received in media chambers () and differing from each other. A measuring apparatus () can detect an overflow of at least one medium () from a medium chamber () via the separator () into the other medium chamber () having the other medium ().
