4 Structure and mode of operation
The torque flange consists of two separate parts: the rotor and the stator. The rotor
comprises the measuring body and the signal transmission elements.
Strain gauges (SGs) are installed on the measuring body. The rotor electronics for
transmitting the bridge excitation voltage and the measurement signal are located centrally
in the flange. The transmitter coils for contactless transmission of excitation voltage and
measurement signal are located on the measuring body's outer circumference. The signals
are sent and received by a separable antenna ring. The antenna ring is mounted on a
housing that includes the electronic system for voltage adaptation and signal conditioning.
Connectors for the torque and speed signals, the voltage supply and the digital output
are located on the stator. The antenna segments (ring) should be mounted more or less
concentrically around the rotor (see Chapter 5).

The speed sensor can be optionally mounted on the stator. The speed is measured
magnetically with an AMR sensor and a magnetic ring. The magnetic ring for
measurement of speed is welded to the flange.
