Partially reusable
Light point measurement of valve stem exposed stroke
For large valve actuators, the point laser triangular displacement is used as the observation route, and the opening and closing displacement and return residual are intended to be output. The page is for project evaluation and does not mean that the development has been completed or has been accepted on site.

Current capabilities and capabilities to be supplemented
Partially reusable
Requires calibration, synchronization or integration
The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.
Gaps in this scenario:It is necessary to add point laser ray intersection or one-dimensional nonlinear distance calibration adaptation; A97 only has a linear area, and A21 is a laser plane interface. Valve internal leakage cannot be determined by the stroke. Only visible target surface geometry is measured, wall thickness, corrosion or pressure bearing capacity is not inferred.
Route-level gaps:It is necessary to add point laser ray intersection or one-dimensional nonlinear distance calibration adaptation; A97 is only in the linear area, and A21 is the laser plane interface
"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Use gauge blocks and stages to cover range and surface conditions and independently report physical error, repeatability, and speckle effects. Mechanical datum, total station or independent displacement meter comparison
