  • Patent number: 11119026
    Abstract: A calibration method and system for a lubrication oil metal debris sensor includes applying an excitation to the lubrication oil metal debris sensor to be calibrated, obtaining a second output signal from the lubrication oil metal debris sensor to be calibrated based on a test metal ball with a known diameter, and determining a sensitivity characteristic parameter of the lubrication oil metal debris sensor to be calibrated according to the diameter of the test metal ball with the known diameter, the second output signal, and a preset data processing model. Large particulate metal balls with large diameter are used as calibration particles. The calibration performed by the combination of the particulate metal ball and the data processing model helps when the signal processing circuit cannot be matched with the actual performance of the sensor and avoids an underestimation of the monitoring capability of the lubrication oil metal debris sensor.
