Rotational speed measuring system,
reference signal (optional)
The optional rotational speed measuring system (also
with the additional reference signal and zero index
option) is integrated into the transducer at the factory, so
no installation is required.

alignment
If the stator is accurately aligned for torque measure
ment, the rotational speed measuring system and the
sensor for the reference signal (zero index) are also cor
rectly aligned. So the two Allen screws on the sensor
head (Fig. 5.9) must not be loosened.
