4.7  Speed measuring system, reference pulse 

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.

Rotational speed measuring system sensor head alignment 
If the stator is accurately aligned for torque measurement, the rotational speed 
measuring system and the sensor for the reference signal (zero index) are also 
correctly aligned. So the two Allen screws on the sensor head (Fig. 5.10) must 

not be loosened. 

 
Important 

  You must not change the position of the sensor head. 

 
Important 

This is a magnetic rotational speed measuring system. 
In applications where magnetic strengths are expected to be high (such as an 
eddycurrent brake), suitable action must be taken to ensure that the max. 
magnetic field strength stated in the specification is not exceeded.
