Patent attributes
A rheometer includes a measuring shaft unit being rotatably mounted in a stationary support unit and having a measuring shaft carrying a measuring part. Transmitting units having optical transmitters are disposed on the support unit and receiving units having optical receivers are disposed on the measuring shaft unit for data transmission therebetween. A measuring sensor disposed on the measuring shaft detects at least one parameter. The transmitting and receiving units are disposed between the measuring shaft unit and the support unit and are associated with one another for exchanging data. The optical transmitters on the support unit transmit data and energy to the optical receivers on the measuring shaft unit. The transmitting units feed or transmit to the optical receivers at least energy required by the optical transmitters on the measuring shaft unit and the measuring sensor to output or transmit data to the optical receivers.
