Description
This system, a very important element of in-line magnetic flux leakage detection, is used for tracking and positioning the in-line magnetic flux leakage (MFL) detector.
When the MFL sensor probe is passing through each marker, the marker can record the exact time and position information, so that the marking and calibration of the detection procedure can be achieved.
In this way, the accumulated error of odometer wheel can be eliminated.
Specification:
- Operation hours: >= 300h
- Number of mark points: >= 500
- Sensing range: depth 0.5 ~ 4m, axial direction ±3m, circumferential direction ±1 m
- Clock stability: <= 0.5 ppm
- Clock precision: 0.01 s
- Mark record error: <= 0.1 s
