The device has a pressure sensor (26) detecting pressure data in a fluid chamber (16), and an ultrasonic sensor (28) for detecting ultrasonic data. A calculation unit (30) evaluates the data and determines the position of a movable separation element i.e. movable piston (10), to be arranged within an accumulator (12) as a separator between a gas chamber (14) and the fluid chamber. A temperature sensor (32) detects temperature data, and is coupled to one of fluid, gas and environmental air. A solid body for a heat storage structure is arranged in the gas chamber. An independent claim is also included for a method for determining a position of a separation element arranged within an accumulator as a separator between a gas chamber and a fluid chamber. |
