5.15 Bearing­monitoring system

5.15.1 Bearing monitoring by Pt 100 resistance thermometer

The gear unit may be fitted with Pt 100 resistance thermometers for monitoring the
bearings. In order to measure the temperatures and/or temperature differences, the
Pt 100 resistance thermometer, which should comply with the requirements of
Directive 94/9/EC, must be connected to a suitable evaluating instrument provided by
the customer. The resistance thermometer has a connection head for the wiring.
A two­conductor circuit is provided by the manufacturer. However, the customer may
also fit a three­ or four­conductor circuit.
For control information, refer to the list of equipment.

For a detailed illustration of the gear unit and the position of the add­on parts, please refer to the drawings
of the gear­unit documentation.
When operating and servicing the components, observe the operating instructions relating to
the components.
For technical data, refer to the data sheet and/or the list of equipment.
5.15.2 Bearing monitoring by shock­pulse transducer
The gear unit may be fitted with measuring nipples for monitoring the bearings. These nipples are intended
for attachment of shock­pulse sensors with rapid­action coupling and are located in the vicinity of the
bearings to be monitored.
