Abstract

A centrifugal separator has a stationary casing and a centrifuge rotor, which is provided in the stationary casing and arranged to rotate around an axis of rotation at a rotary speed and which includes a plurality of nozzles for discharge of a product from the centrifuge rotor. The centrifugal separator includes a sensor device which includes a transfer element, which has a first part and a second part and which is configured to be mounted in such a way that the first part is located inside the stationary casing and outside the centrifuge rotor and that the second part is located outside the stationary casing. At least the first part of the transfer element has an elongated shape, a receiving head, which includes the first part of the transfer element. The sensor device further includes a sensor element, which is mounted to the second part of transfer element and which is configured to sense vibrations and/or shock pulses propagating from the receiving head to the sensor element, and an evaluation unit, which communicates with the sensor element for transmitting signals from the sensor element to the evaluation unit. The transfer element is mounted in the stationary casing, directed such that the end face of the receiving head faces the passing jets from the nozzles during rotation of the rotor. A centrifugal separator with such a sensor device is also disclosed.
