4. MAINTENANCE, REPAIR & CALIBRATION
4.1 MAINTENANCE
Magtrol TM Series In-Line Torque Transducer are virtually maintenance-free. This is due to the following
aspects of their construction:
▪
Lifelong lubrication of the bearings.
▪
Transmission of the torque signal from the rotating measuring elements to the signal processing elec-
tronics by a process of induction rather than by using slip rings. This eliminates mechanical wear.
However, it may be necessary to change the bearings after extended use. The theoretical lifetime of the
bearings is
5 000 hours and Magtrol recommends that the bearings be replaced after this time. Bearings
should be replaced as soon as they start showing signs of wear. Higher wear occurs when the transducer
is operated outside its optimal working conditions. This is especially true when the transducer is operated
at excessive rotational speeds, which results in the generation of axial and radial forces on the bearings.
THE USER MUST NOT ATTEMPT TO CHANGE OR REPAIR THE BEARINGS OR ANY OTHER
COMPONENTS HIMSELF. FOR ALL MAINTENANCE OR REPAIR OPERATIONS, PLEASE RETURN
THE SENSOR TO MAGTROL.
SIMILARLY, THE USER SHOULD NOT ATTEMPT TO CARRY OUT REVISIONS OR REPAIRS OF
ANY KIND ON THE MECHANICAL OR ELECTRONIC COMPONENTS MAKING UP THE TRANS-
DUCER. IF A PROBLEM IS SUSPECTED, MAGTROL SHOULD BE CONTACTED SO THAT AR-
RANGEMENTS CAN BE MADE TO PERFORM ANY REPAIRS IN THE FACTORY.
FAILURE TO COMPLY MAY RESULT IN SERIOUS DAMAGE TO THE TRANSDUCER OR MAY IN-
VALIDATE THE WARRANTY.
The TM Sensor housing is sealed . If there is any evidence that the housing has been opened
and unauthorized modifications have been attempted,
the warranty will be invalidated.
