Fig. 4.2 Mechanical construction with a rotational speed measuring system
In the version with a rotational speed measuring system, the transducer can
also be fitted with a sensor head for a reference signal (zero index) for measur­
ing the angle of rotation. The magnet to be used for this is located on the inner
surface of the flange. The sensor head for sampling the reference signal is
located in the bracket above the rotational speed sensor.
