INCOMING MATERIAL CONTROL
All raw materials are verified before production:
Stainless steel grade verification (304 / 316L confirmation)
Sensor element electrical performance screening
PCB and electronic component stability inspection
Mechanical housing tolerance inspection
Only qualified materials are released into production flow.
IN-PROCESS QUALITY CONTROL
During assembly, we control:
Sensor alignment precision
>>
Signal output stability during integration
>>
Sealing performance under pressure conditions
>>
Electrical isolation and safety verification
>>
Structural integrity under vibration conditions
>>
Each stage is recorded for batch-level traceability.
CALIBRATION & FUNCTION VERIFICATION
Calibration is performed using controlled testing environments.Before shipment, instruments undergo application-based calibration:
- Flow simulation calibration for flow meters
- Pressure response calibration for transmitters
- Temperature curve verification for thermal sensors
- Level signal stability validation for tank systems
RELIABILITY VALIDATION TESTING
These tests ensure suitability for industrial 24/7 operation.Selected product batches undergo:
Continuous operation endurance testing
Thermal cycling simulation
Vibration resistance validation
Long-term signal drift observation
TRACEABILITY SYSTEM
This supports industrial procurement audits and after-sales tracking.Each product batch is traceable through:
- Production batch ID
- Component sourcing records
- Calibration data records
- Inspection approval logs
FINAL SHIPMENT INSPECTION
Before delivery:
Output signal verification
Mechanical inspection
Packaging protection for international logistics
Documentation check (manuals / datasheets / certificates)
