Hall current sensor for aerospace applicationsTechnical indicators are objective criteria for characterizing the performance of a product. Understanding the technical specifications is helpful for selecting and using the product correctly.The technical indicators of Hall current sensors used in aerospace are divided into two categories: static indicators and dynamic indicators. The static indicators mainly assess the performance of aerospace Hall current sensors under static and unchanged conditions, including resolution, repeatability, sensitivity, linearity, return error, threshold, creep, stability, etc.Dynamic indicators mainly examine the performance of sensors under rapidly changing conditions, including frequency response and step response. 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.

because航天用霍尔电流传感器There are numerous technical indicators and various literature descriptionsDifferent perspectives can lead to different interpretations and even misunderstandings and ambiguities among individuals. Therefore, the following are the main technical indicators for sensors to be interpreted:

1. Resolution and resolution:

Definition: Resolution refers to the ability of a sensor to detect the measured objectzuiSmall changes. Resolution refers to the ratio of resolution to full-scale value.

Interpretation 1: Resolution is the sensor'sThe basic indicator characterizes the sensor's ability to distinguish the measured object. Other technical indicators of sensors are based on resolutionzuiDescribing it as a small unit.For sensors and instruments with digital display function, resolution determines the display of measurement resultszuiSmall digits. For example, the resolution of an electronic digital caliper is 0.01mm, and its indication error is ± 0.02mm.Interpretation 2: Resolution is a unitabsolutelyNumerical value. For example, the resolution of a temperature sensor is 0.1 ℃, the resolution of an acceleration sensor is 0.1g, and so on.Interpretation 3: Resolution is a concept that is closely related to resolution and characterizes the sensor's ability to distinguish the measured object.The main difference between the two is that resolution is expressed as a percentage of the sensor's resolution, which is a relative number without dimensions. For example, if the resolution of the temperature sensor mentioned above is 0.1 ℃ and the full range is 500 ℃, then its resolution is 0.1/500=0.02%.

电流互感器或电流互感器是通过二次电压来检测电流，二次电压与二次线圈中的电流成比例。它是一种工业变压器，它将电压或电流的大值在次级线圈中转换成小得多的值。测量通过次级输出进行。
