General information The microwave sensors are being developed in cooperation with the chair for high frequency engineering of the technical faculty of the Christian-Albrecht-University in Kiel. The measurement accuracy of the microwave sensor in the laboratory is better than 0.1%. Linearity The complete linearity of the microwave sensor allows measurements with very dry concrete as well as very wet concrete. Temperature stability The microwave sensors for installation in mixers type 6/10 and type 7/10 are heat-resistant up to 60°C. This guarantees that the measured value remains stable under high temperatures and does not vary. Wear Our microwave sensor are extremely wear resistant. The ceramic measuring field is 10 mm thick and protected against lateral damage through a hardened shell. The microwave sensor is also equipped with a wearing head which can be exchanged by the customer. Mixer with a turning mixing trough The microwave sensor type 7/10 for installation in the mixer with a turning mixing trough has a temperature measuring device installed in the microwave sensor and does not need an external temperature sensor.
