Torque flanges consist of two separate parts: the rotor
and the stator. The rotor comprises the measuring body
and the signal transmission elements.
Strain gauges (SGs) are mounted 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 signal, the voltage supply and
the speed signal (option) are located on the stator. The
antenna ring should be mounted more or less
concentrically around the rotor (see Chapter 5).
A magnetic or optical sensor performs the speed
measurement. With a magnetic measuring system, a
magnetized rotor is sampled by means of a
MagnetoResistive sensor (MR).
The optical sensor works on the infrared transmitted light
barrier principle. The reference pulse is generated by a
magnet in the slotted disc and a magnetoresistive
sensor. In the case of option 2 (speed measuring
system), code L, the speed sensor is mounted on the
stator, the customer attaches the associated slotted disc
on the rotor. In the case of code H, the slotted disc is
already mounted on the rotor.
