We choose磁阻與霍爾傳感器When it comes to the productThe repeatability index is also a parameter that needs to be carefully considered, and there are usually multiple interpretations of this parameter：
Definition: Repeatability of Magnetic Resistance and Hall SensorLity refers to the degree of difference between measurement results when multiple repeated measurements are taken along the same direction and under the same conditions. Also known as repetition error, reproduction error, etc.Interpretation 1: The repeatability of magnetoresistance and Hall sensors must be the degree of difference between multiple measurement results obtained under the same conditions. If the measurement conditions change and the comparability between measurement results disappears, it cannot be used as a basis for assessing repeatability. 這種電流傳感技術的另一種方法是使用PCB跡線作為并聯電阻器。由于PCB的銅線提供非常小的電阻，因此可以使用銅線來測量電流。然而，在這種替代方法中，要獲得準確的結果，幾個依賴項也是一個巨大的問題。

unscramble2Magnetic resistance and Hall sensorThe repeatability characterizes the dispersion and randomness of sensor measurement results. The reason for this dispersion and randomness is that there are inevitably various random interferences inside and outside the sensor, which cause the sensor tozuiThe final measurement result is manifested as a characteristic of a random variable. The working principle of Hall effect sensors is similar to that of flux gate sensors, but there is a difference between the two. The difference lies in the core materials. The flux gate sensor uses a saturated inductor, while the Hall effect sensor uses a hollow core.Interpretation 3: The quantitative expression method of repeatability can use the standard deviation of random variables.Interpretation 4: For multiple repeated measurements, if the average of all measurement results is taken aszuiThe final measurement result can obtain higher measurement accuracy. Because the standard deviation of the mean is significantly smaller than the standard deviation of each measurement result.
