What kind of sensor is appropriate for aluminum coil thickness measurement?
Use two sensors of ZLDS10X series to make a thickness gauge
You can use ZLDS10X series sensor.
You can use laser sensor.
Thickness measurement can be divided into single-point and two-point thickness measurement, the principle of which is to measure thickness of aluminum coil through distance measure sensor. Single-point thickness measurement is to calculate the thickness by measuring the distance between the aluminum coils and then subtracting the distance with fiducial point. Double-point thickness measurement is to calculate the thickness by setting a proper distance between two sensors, putting the aluminum coil between them and measuring the distance and then subtracting the distance with initial distance, which is more accurate than single-point measurement. (Professional thickness measurement sensor is also based on single-point or two-point thickness measurement.) The distance measurement sensor can be divided into laser sensor, eddy current sensor and so on. The measuring range of laser sensor is larger than that of eddy current sensor, but less accurate. The While the accuracy of eddy current sensor is around 0.01%, and the measuring range is around several millimeters to more than ten millimeters.
