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 contains the elec­
tronics for voltage adaptation and the signal conditioning.
Connector plugs for the torque and rotational speed signals, the voltage supply
and digital output, are located on the stator. The antenna segments (ring)
should be mounted concentrically around the rotor (see Chapter 5).
