FAQ
Q: Does this sensor make contact with the workpiece during measurement?
A: No, it adopts eddy current non-contact measurement mode, which will not scratch or damage the surface of metal workpieces.
Q: Can it measure different metal materials such as iron, stainless steel and aluminum?
A: Yes, characteristic parameters of common metals have been pre-stored, and output curve correction can be carried out according to the target material.
Q: Will the change of ambient temperature greatly affect the measurement result?
A: It has excellent temperature stability, so the measurement error brought by ambient temperature fluctuation is controlled at a very low level.
