We choose霍尔电阻式传感器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 Hall resistance sensorsLity 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 Hall resistance 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. 磁芯的磁导率与饱和水平成正比，因此电感也会发生变化。磁通门传感器通过分析电感值的变化来检测电流。电流越大，电感越小；电流越小，电感越大。

unscramble2Hall resistance 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 Hall effect current sensor measures the magnetic flux proportional to the primary current, without direct contact with the primary circuit; The combination of Hall elements and magnetic circuits provides an excellent solution for measuring AC/DC currents, with current isolation and zero insertion loss.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.
