Sensoranordning och centrifugalseparator

The invention refers to a sensor device and a centrifugal separator (1). The centrifugal separator comprises a stationary casing (2) and a centrifuge rotor (3), which is provided in the stationary casing and comprises nozzles (7) for discharge of a product. The sensor device comprises a transfer element (21), which has a first part (21') and a second part (21"). The first part (21') is located inside the casing and outside the centrifuge rotor and the second part (21") is located outside the casing. A receiving head (23) is comprised by the first part of the transfer element. A sensor element (25) is mounted to the second part of the transfer element. An evaluation unit (26) is connected to the sensor element via a conduit (27) for transmitting signals from the sensor element to the evaluation unit. The sensor element senses vibrations propagating from the receiving head to the sensor element. The transfer element is movable in relation to the centrifuge rotor and the stationary casing so that the position of the receiving head is adjustable.
