Making outline
- Form a metal diaphragm, mechanically clamp it to an integrally ported body and link displacement to a pointer; calibrate against independent gravity pressure and check hysteresis/leakage.
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"New physical sensor subassembly, not pressure-instruments itself; pressure/vacuum range unqualified."
