The measurement range of eddy current displacement sensors is typically influenced by the following factors:
1. Sensor Design: The measurement range of eddy current displacement sensors is affected by the sensor's design and manufacturing process. Design parameters such as coil dimensions, materials, number of coils, and layout directly impact the sensor's measurement range.
2. Material Properties: The material characteristics of the measured object exert a certain influence on the sensor's range. Different materials affect eddy currents to varying degrees, so the material properties of the object being measured impact the selection of the sensor's range.
3. Drive Current: The measurement range of eddy current sensors is also affected by the drive current. Generally, a higher drive current enables a wider measurement range.
4. Probe Size: The size of the eddy current sensor probe also impacts its measurement range. Larger probe dimensions typically correspond to greater measurement ranges.
5. Environmental Conditions: Environmental factors such as temperature and humidity may also exert some influence on the measurement range of eddy current sensors.
Therefore, the measurement range of eddy current displacement sensors is determined by a combination of multiple factors. The appropriate range must be selected based on the specific application scenario and the characteristics of the measured object.
