Quality Control Standard Testing
  • 100% testing of all sensors.
  • Each sensor is checked for proper output at room temperature as well as an elevated temperature.
  • Insulation resistance of every sensor is checked.
  • Each sensor is checked by QC personnel to assure the physical sensor matches the, i.e. sensor type, fitting options, lengths, etc.
  • When a sensor passes complete inspection, it is given an engraved traceability number. This number allows A ONE UNION to resurrect a material test report, calibration data and part number of unit.
