Record notes
Technical context to review before RFQ.
Siemens QBM81-3 is maintained as differential pressure switch with manufacturer-owned Siemens source evidence attached to the record. Accepted source: Siemens OEII product page for BPZ:QBM81-3.
The record now avoids old generic sourcing wording it keeps the Siemens source visible for RFQ matching, but it does not claim stock, price, warranty, channel-status verification, lead time, or final compatibility.
Before quote approval, confirm BOM line, software or license version, Siemens platform, delivery format, quantity, condition preference, and destination country.
Procurement note: use this QBM81-3 record to align exact part identity, source evidence, condition, quantity, destination country, and quote approval before treating it as a replacement or spare.
It does not imply stock, channel-status verification, warranty, lead time, or final compatibility without RFQ review. RFQ note: treat Siemens QBM81-3 as a procurement review record within Sensors.
Before approval, the team checks exact part identity, manufacturer evidence, revision, condition, quantity, destination country, supply route, and differential pressure switch fit
