6.6.3.1 Temperature monitoring
Temperature monitoring of
rolling bearings
Temperature sensors are responsible for monitoring the temperature
of the bearings.
Temperature sensors measure the temperature values at rolling
bearings.
6.6.3.2 Rotation speed monitoring
Rotation speed monitoring
The pulse shield, mounted at the end of the shaft on the drive side, is
responsibl
e for monitoring the speed. The encoder collects the
impulse for further processing.
