4 Structure and Mode of Operation
The torque flange consists of two separate parts: the ro
tor 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 trans
mission of excitation voltage and measurement signal are
located on the measuring body's outer circumference.
The signals are sent and received by a separable an
tenna ring. Separable antenna ring not for Option 7,
Code U. The antenna ring is mounted on a housing that
contains the electronics for voltage adaptation and the
signal conditioning.
Connector plugs for the torque and rotational speed sig
nals, the voltage supply and digital output, are located on
the stator. The antenna segments (ring) should be moun
ted concentrically around the rotor (see Chapter 5).
