Cenith MPS-Plus not only makes test processes extremely efficient, unlike other measurement processes it also provides highly accurate error analyses. To demonstrate, we shall compare the Cenith MPS-Plus featuring LCW technology® with a rotary probe.
Equipment required:
- MPS electronic box including coil lead
- Magnetization yoke PMJ
- Test coil
- 2 protective nozzles
- Options:
- Yoke stand
- Sliding table
- Roller guides
- De-magnetization
- Colour marking
Operation
Signals and parameters are set through a separate touchscreen. Alternatively, a standard monitor can be connected with a mouse/trackball. The RS232/485 can be used for control and parameter setting as a test system in conjunction with a BDE system. Test signals can also be transmitted to the BDE system via a control interface for subsequent processing (can be installed customer-specifically).
Connection to Process Monitoring System
Process monitoring systems manufacturers sometimes offer connection from the Cenith-MPS to the customer system. In this case there is no need for a terminal to be installed.
2 longitudinal errors with different depths:
LCW longitudinal: the signal height changes with the depth of the longitudinal error.
LCW transverse: the beginning and end are identified, signal height depends on the error depth.
Rotary probe: signal remains the same over the entire error length – irrespective of the error depth.
4 longitudinal errors with different depths:
LCW longitudinal: the signal length changes with the length of the longitudinal error. Very short longitudinal errors are measured as a transverse signal.
LCW transverse: the beginning and end are identified, signal height remains constant for the same error depth.
Rotary probe: constant signal over the entire error length.
1 longitudinal error as an inclusion:
LCW longitudinal: error signal over the entire inclusion length.
LCW transverse: beginning and end of inclusion are identified. The error in the middle is caused by the point of impact from the two rods.
Rotary probe: The inclusion is not identified as rotary probes only have a very low penetration depth.
