Structure and mode of operation

The torque flange (Option 2, code N) consists of two separate parts: the rotor
and the stator.
The rotor comprises the measuring body and the signal transmission ele
ments.
Strain gages (SGs) are mounted on the measuring body. The rotor electronics
for transmitting the excitation voltage and the measurement signal are located
centrally in the flange. The transmitter coils for the noncontact transmission of
excitation voltage and measurement signal are located on the measuring
body. The signals are sent and received by a separable antenna ring. The an
tenna ring is mounted on a housing that includes the electronic system for
voltage adaptation and signal conditioning.
Connectors for the torque signal, the voltage supply and the speed signal (op
tion) are located on the stator. The antenna ring should be mounted more or
less concentrically around the rotor (see chapter 4).
Speed measurement is effected by a magnetic field dependent resistor and a
ring gear attached to the rotor.
