SENSOR ASSEMBLY

A sensor assembly for detecting at least one material property of a harvested material picked up by a self-propelled harvesting machine and passing through the sensor assembly is disclosed. The sensor assembly includes at least one sensor element which is arranged on a plate-shaped carrier, and an evaluation circuit for evaluating signals which the at least one sensor element generates on the basis of physical contact of the plate-shaped carrier with the harvested material. The plate-shaped carrier is designed as a ceramic-containing plate with a contact surface, which is in contact with the harvested material, and a sensor surface facing away from the contact surface. The at least one sensor element and the evaluation circuit are arranged thereon on the sensor surface of the plate-shaped carrier facing away from the harvested material.
