Electrical Setup
The electronics integrated in the sensor consistsof two parts.
The first part is in the stator and has following tasks:
Stabilization of the supply voltage
Electric supply of the rotor electronics through the rotating transformer
Preparation of the measurement signal from the rotor
Transmission of the torque measurement signal to the cable connection
The second part of the electronics is placed in the rotor of the torque sensor
with following functions:
Supply of the SG full bridge with DC voltage
Preparation of the electrical torque measurement signal
Transmission of the measurement signal to the stator

Mechanical Assembly
4.1
Rotor Assembly
Caution:
During the assembly inadmissibly large forces may not act on the sensor or the
couplings. Connect the sensor electrically during the assembly and observe the signal, the
measurement signal may not exceed the limit values.
To avoid falling down, the sensor must be supported during the assembly.
Admissible assembly offset from rotor to stator:
4.2 Stator Assembly
The sensor is installed into the shaft string through flanges. Prior to the assembly, flanges must be
cleaned with solvent (e.g. acetone), they must be free of foreign particles. The surface of the flange must
have an evenness of minimum 0,02 mm.
For transportation and easier assembly, the torque sensor is delivered with fixing plates.
The optimal
axial position of Stator to Rotor
is defined by fixing plates.
(per plate 3 screws M4x10)
Mounted Fixing Plates
Removed Fixing Plates
Without Fixing Plates
Tighten screws evenly on the flanges. Torque transmission by surface pressure, only. The installation and
alignment of the torque sensor occurs with mounted fixing plates.
Use appropriate tightening torques for the screws of
strength 10.9
with suitable length. The screws
should be secured with screw locks (e.g. LOCTITE No. 242).
