Sensor buys often collapse to price and range, while real risk hides in lot consistency, supply life, failure analysis, and field support. Senseiot serves OEMs, integrators, and EPCs—we condensed the ten RFQ questions that prevent most late-stage disputes into a checklist for procurement, R&D, and project leads.
1. Do range and accuracy match real conditions—not datasheet extremes?
Ask for an application memo with your temperature, humidity, pressure, and gas background—not just “we have a part number.” Request expected drift, T90, and cross-sensitivity in your environment.
Cross-check scenarios in industry application solutions.
2. Lot consistency and traceability
Confirm Cpk, calibration records, and batch traceability. Clarify 100% cal vs sampling and mixing batches in production.
Cheap modules without consistency data often fail at mass production.
3. Certification roadmap
Verify ATEX, IECEx, AEC-Q, medical paths for target markets. Distinguish “planned” vs “held” certificates to protect milestones.
4. Interfaces and documentation
Digital: register map, timing, reference drivers. Analog: compensation curves and load limits. Fault codes and sample code shorten integration.
Open protocols beat proprietary stacks in multi-vendor buildings and plants.
5. Calibration, maintenance, consumables
Ask sensor life, replacement cycles, membrane/filter costs, and lead times. TCO beats first price.
Request Senseiot calibration SOPs via request a quote.
6. Failure analysis and FAE SLA
RMA analytics, known failure modes, and 24–48 h remote support SLAs reduce downtime cost.
7. Long-term supply and EOL
Five- to ten-year programs need MOQ, lead time, EOL notice windows, and migration guides.
8. Sample, pilot, and production bridge
Confirm production-representative samples and pilot-to-mass pricing transitions.
Browse the sensor catalog and contact support for eval units and FAE reviews.
9. Commercial terms and risk sharing
Define warranty, non-conformance returns, force-majeure lead times, and liability when customer environment data was wrong. Many disputes surface at 6–12 months when reality diverges from assumptions—contracts need joint retest clauses.
Use acceptance lots on first MP orders before locking price and MOQ. Senseiot offers application review meetings via contact support.
10. Summary: make hidden costs visible
Put all ten items in RFQ scorecards with evidence links. Weight technical fit 40%, supply/service 35%, commercial 25%—not lowest price alone.
Strong vendors flag risks instead of claiming “we do everything.” Senseiot aims to be a long-term partner from product selection through production O&M.
