Where to Mount a Magnetostrictive Displacement Sensor: The Wrong Position Moves Both Stroke and Accuracy
On the same machine, the reading is always the distance between the fixed end of the rod and the magnet, so where the unit sits is where the datum sits. Mounted on the frame, mounted on the moving carriage, or with both ends moving — the three arrangements measure three different things. This covers what each pattern actually measures, the three checks to run once position is fixed, and how far a measuring line may sit from the axis of motion before angular error starts to dominate.
