We choose国产霍尔电流传感器排名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 domestic Hall current sensor ranking (Repeatabi)Lity 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 the ranking of domestic Hall current 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. 基于电流互感器的电流传感技术由于具有很高的电流测量能力，主要应用于电网中。很少有钳形电表也使用电流互感器来测量交流电。

unscramble2Ranking of Domestic Hall Current SensorsThe 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 basic structure of a flux gate sensor. There are two coils, primary and secondary, wound around a saturated inductor core. The change in current can alter the magnetic permeability of the magnetic core, thereby changing the inductance of other coils.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.
