Small current Hall closed loop current sensorTechnical 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 small current Hall closed loop current sensors are divided into two categories: static indicators and dynamic indicators. The static indicators mainly assess the performance of small current Hall closed loop 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. In addition, acceptable sensitivity and interference also need to be considered. Due to the inability to meet every factor, some compromises will be made based on the priority of application requirements to compromise one feature with another.

because小电流霍尔闭环电流传感器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%.

钳位式交流电流传感器就是为了限度地利用这些特性而研制的。随着工业4.0能源管理系统市场的扩大，韦克威已开发出一系列兼容30A至600A的交流电流传感器，以满足对大电流支持的需求。这些产品是一触式夹具，这意味着它们很容易连接到现有的电力设备。
