电涡流探头是一种基于电涡流效应工作的传感器探头。330901-00-90-10-02-05的工作原理是：当探头的头部靠近导体时，会在导体表面产生电涡流。这个电涡流会产生一个反向的磁场，这个反向磁场与探头的原始磁场相互作用，从而改变探头头部的线圈阻抗。通过测量这个阻抗的变化，就可以非接触地测量导体与探头之间的距离。

电涡流探头通常用于测量位移、振动等参数，也可以用于金属材料的无损检测。它的优点包括非接触测量、高灵敏度、高分辨率、快速响应等。然而，电涡流探头也有一些限制，例如它只能用于测量金属导体，且受温度、电导率、磁导率等因素的影响。

电涡流探头通常由传感器、前置器和电缆三部分组成。传感器是探头的核心部分，330901-00-90-10-02-05由绕在非金属骨架上的矩形截面线圈组成。 ，它将传感器产生的电涡流信号转换为标准电压信号。电缆则用于连接传感器和前置器，传输测量信号。

在安装电涡流探头时，需要注意探头与被测物体之间的距离和角度，以及探头的固定方式。一般来说，探头与被测物体之间的距离应该在线性范围内，以保证测量的准确性和稳定性。同时，探头应该固定在一个稳定的位置，避免由于振动或温度变化等因素引起的误差。

总之，电涡流探头是一种基于电涡流效应工作的传感器探头，330901-00-90-10-02-05具有非接触测量、高灵敏度、高分辨率等优点，广泛应用于位移、振动等参数的测量以及金属材料的无损检测。

Eddy current probe is a kind of sensor probe based on eddy current effect. The 330901-00-90-10-02-05 works by creating an electrical eddy on the surface of the conductor when the head of the probe is close to the conductor. This eddy creates a reverse magnetic field that interacts with the probe’s original magnetic field to change the coil impedance at the probe head. By measuring this impedance change, the distance between the conductor and the probe can be measured contactless.

Eddy current probes are usually used to measure displacement, vibration and other parameters, and can also be used for non-destructive testing of metal materials. Its advantages include non-contact measurement, high sensitivity, high resolution, fast response, etc. However, the eddy current probe also has some limitations, such as it can only be used to measure metallic conductors and is affected by temperature, conductivity, permeability and other factors.

The eddy current probe is usually composed of a sensor, a preprocessor and a cable. The sensor is the core part of the probe, 330901-00-90-10-02-05 consists of a rectangular coil wound around a non-metal skeleton. The preprocessor is a signal conversion device, which converts the eddy current signal generated by the sensor into a standard voltage signal. Cables are used to connect sensors and precursors to transmit measurement signals.

When installing the eddy current probe, it is necessary to pay attention to the distance and Angle between the probe and the object to be measured, as well as the way the probe is fixed. In general, the distance between the probe and the object to be measured should be in a linear range to ensure the accuracy and stability of the measurement. At the same time, the probe should be fixed in a stable position to avoid errors caused by factors such as vibration or temperature changes.

In short, the eddy current probe is a sensor probe based on the eddy current effect, 330901-00-90-10-02-05 has the advantages of non-contact measurement, high sensitivity, high resolution, etc., widely used in displacement, vibration and other parameters measurement and non-destructive testing of metal materials.
