Multiple displacement readings can turn a long-shaft inspection from a single peak into an error map. That value depends on more than the sensor: support geometry, nohoanga datum, whakapā rangahau, rotation/indexing, synchronization, environmental conditions and the calculation rule all affect what is being reported.
This Tier C guide explains a validation framework. It does not state that StraighteningTech uses LVDTs, provides a particular sensor count, sampling rate, whakatau, calibration interval or measurement capability. Those facts require an approved system description and a correlation study.

Define the Characteristic Before Selecting Sensors
First state whether the acceptance characteristic is centerline straightness, local bow, runout relative to a datum, profile deviation or another controlled result. A sensor voltage or displacement trace is not itself the customer requirement. The inspection plan must identify datum features, tautoko, nga teihana, orientations, whanganga, calculation, units, limits and the state in which the part is accepted.
| Element | Question to close |
|---|---|
| Datum | Which features establish the reference axis or surface? |
| Tautoko | Does it replicate the customer or released-part condition? |
| Probe path | Are contact points functional surfaces and protected from damage? |
| Stations | Do they capture known bend zones and feature transitions? |
| Rotation/indexing | How is orientation preserved between readings? |
| Calculation | How are readings converted into the controlled characteristic? |

Treat the Measurement Chain as One System
An LVDT may be suitable for relative displacement, but the measured result also includes sensor mounting, fixture deflection, signal conditioning, timing, part seating and operator or automation behavior. Record every element in the chain so a later shift in the result can be investigated.


*Whakaahua aria hangarau. Fixture stiffness, sensor position and guarding require project-specific engineering.*
The controlled procedure should cover sensor identification, reference/master check, mounting condition, cable protection, zero method, sample orientation, support cleanliness, data acquisition settings and data retention. A repeated reading from an unstable fixture is not evidence of repeatability.
Synchronize Location, Orientation and Readings
Multipoint data is useful only when each value can be assigned to a known position and condition. If the part rotates or moves, define the encoder/index, station coordinate, direction of travel, dwell or sampling condition, and what happens if a signal is missing. The result should preserve the raw or traceable source data needed to reconstruct the map.
Avoid interpreting a localized peak without checking seating and contact. Reseat tests, reversed orientation where appropriate and repeated baseline reads can distinguish a part feature from a false indication.
Correlate to Released-Part Acceptance
Measurement during clamping or correction may be useful for process control, but it does not automatically prove the released shaft meets the requirement. Compare the line method with an approved released-part method on representative samples across normal variation. Tirohia utaina me te inenga tika i tukuna for the boundary.


*Whakaahua aria hangarau. The reference method, supports and acceptance calculation must be controlled by the approved quality plan.*
A correlation plan should define matched samples, blind comparison where practical, datum/support equivalence, calibration status, bias review, repeatability/reproducibility review, allowed difference, escalation and change-control rules.
