Publication integrity record
Notification sensor arrangement for a differential pressure sensor and a method for outputting a sensed warning signal
This page is the evidence record. It changes as evidence arrives: a trusted timestamp, an independent retrieval, a custody deposit. The disclosure itself (/p/OT-2026-000000149) never changes.
