Abstract
The invention relates to a measuring arrangement for measuring the density of a product by means of microwaves. The measuring arrangement comprises a first microwave resonator, from which, in operation, microwaves enter a product area, and a device for compensating for environmental influences and disturbance variables affecting the measuring signal of the first microwave resonator. According to the invention, the compensation device comprises a second microwave resonator, which is shielded towards the product area with respect to microwave radiation.
