3500/05-01-02-05-00-01 传感器 用于测量电磁场的强度

3500/05-01-02-05-00-01近场探头是一种传感器，用于测量电磁场的强度、方向和频率等参数。这种传感器内部包含一组线圈，当靠近磁场源时，磁场会穿过线圈并导致线圈内部的电路发生变化，从而产生电动势。这个电动势的大小和方向可以用来确定磁场的强度和方向。
近场探头通常被应用于无线电、通信、雷达、天线、电磁兼容性等领域的测试和测量，还可以用于电磁波的辐射和吸收等研究。此外，在电子器件的设计和测量中，近场探头也发挥着重要作用。例如，在电路板测试中，近场探头可以通过测量辐射和传导信号的变化来确定故障的位置或原因。
近场探头的工作原理基于法拉第电磁感应定律，即当磁通量变化时，会在导体中产生电动势。在医学领域，近场探头也用于生物电信号的检测和研究，如心电图和脑电图的实时监测和记录。
在选择和使用近场探头时，需要考虑探头的类型、适用范围以及保护和稳定性等因素。例如，不同类型的探头适用于不同的信号类型和频率范围，如磁场探头、电场探头和谐波探头等。同时，探头的使用还需要注意保护，以确保测量的准确性和稳定性。
总之，近场探头作为一种传感器，在多个领域中都有广泛的应用，是电磁场测量和电子设备测试的重要工具。

3500/05-01-02-05-00-01 A near-field probe is a sensor used to measure parameters such as the intensity, direction and frequency of an electromagnetic field. This sensor contains a set of coils inside, and when near a magnetic field source, the magnetic field passes through the coil and causes the circuit inside the coil to change, creating an electromotive force. The magnitude and direction of this electromotive force can be used to determine the strength and direction of the magnetic field.
The near-field probe is usually used in the test and measurement of radio, communication, radar, antenna, electromagnetic compatibility and other fields, and can also be used in the radiation and absorption of electromagnetic waves. In addition, near-field probes also play an important role in the design and measurement of electronic devices. For example, in circuit board testing, near-field probes can determine the location or cause of a fault by measuring changes in radiation and conducted signals.
The working principle of the near-field probe is based on Faraday’s law of electromagnetic induction, which states that when the magnetic flux changes, an electromotive force is created in the conductor. In the medical field, near-field probes are also used for the detection and research of bioelectrical signals, such as the real-time monitoring and recording of electrocardiograms and electroencephalograms.
When selecting and using near-field probes, factors such as the type of probe, application range, and protection and stability need to be considered. For example, different types of probes are suitable for different signal types and frequency ranges, such as magnetic field probes, electric field probes, and harmonic probes. At the same time, the use of the probe also needs to pay attention to protection to ensure the accuracy and stability of the measurement.
In short, as a kind of sensor, near field probe has a wide range of applications in many fields, and is an important tool for electromagnetic field measurement and electronic equipment testing.
