Description
Advantages of eddy current sensors 1, eddy current sensor is a non-contact linearization measurement tool, can be static and dynamic non-contact, high linearity, high resolution measurement of the measured metal conductor distance from the probe surface. The measurement accuracy of eddy current sensor will be affected in the process of measurement. 2, when the sensor characteristics and the conductivity of the measured body, due to the coexistence of eddy current effect and magnetic effect, the magnetic effect reacts on the eddy current effect, making the eddy current effect weakened, that is, the sensitivity of the sensor is reduced. When the measured body is a weak magnetic permeability material (such as copper, aluminum, alloy steel, etc.), due to the weak magnetic effect, the eddy current effect is relatively strong, so the sensor sensitivity is high.
3. The irregular surface of the measured body will bring additional errors to the actual measurement, so the surface of the measured body should be smooth and smooth, and there should be no defects such as bumps, holes, nicks, grooves and so on. In general, the measured surface roughness of vibration measurement is required to be between 0.4um and 0.8um; For displacement measurement, the measured surface roughness is required to be between 0.4um and 1.6um.
4, the eddy current effect is mainly concentrated on the surface of the tested body, if the residual magnetic effect is formed during the processing, and the uneven quenching, uneven hardness, uneven metallographic organization, and uneven crystalline structure will affect the characteristics of the sensor. During vibration measurement, if the residual magnetic effect on the surface of the measured body is too large, the measurement waveform will be distorted.
