Structure and mode of operation
The torque flange consist of two separate parts: the rotor and the stator. The
stator comprises an antenna ring and a housing.
Strain gauges (SGs) are mounted on the rotor. The rotor electronics for
transmitting the bridge excitation voltage and the measurement signal are
located centrally in the flange. The coils for the non‐contact transmission of
excitation voltage and measurement signal are located on the rotor'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
concentrically around the rotor (see Chapter 4).
In the case of the speed measuring system option, the speed sensor is
mounted on the stator, the customer attaches the associated slotted disc on
the rotor. The optical speed measurement works on the infrared transmitted
light principle.
