Factory Acceptance Testing (FAT) for Temperature Sensors

Factory Acceptance Testing (FAT) for Temperature Sensors

Factory Acceptance Testing (FAT) is a comprehensive pre-shipment verification process designed to ensure that every temperature sensor performs accurately and reliably before it reaches your facility. At Acez, each RTD, thermocouple, and resistance temperature detector undergoes controlled and documented testing at our facility to confirm compliance with technical specifications and industry standards. This proactive quality control approach ensures that your instrumentation arrives fully verified, minimizing operational risk and maximizing confidence from the moment of installation.

Our structured testing procedures are carried out by experienced technicians using calibrated reference equipment to validate electrical and thermal performance.

  • Resistance Verification for RTDs – Measurement at standard reference points such as the ice point (0°C) to confirm nominal resistance values and accuracy class compliance.

  • Millivolt Output Testing for Thermocouples – Validation of output signals at defined reference temperatures to ensure correct EMF performance.

  • Signal Output & Response Testing – Confirmation of sensor responsiveness, stability, and repeatability under controlled conditions.

  • Wiring & Construction Inspection – Detection of potential wiring faults, insulation issues, or assembly defects.

  • Performance Documentation – Detailed test reports provided for traceability and quality assurance compliance.

This rigorous factory testing process helps detect manufacturing defects, calibration drift, and configuration errors before shipment, reducing installation delays and preventing costly downtime. It is especially critical for industrial temperature monitoring applications, safety-related systems, and process-critical operations where early sensor failure is not an option.

Ensure your sensors perform correctly from day one. Contact Acez today to schedule Factory Acceptance Testing for your temperature instruments and safeguard your process reliability.
