Mutual influences of two measuring chains
Two eddy current measuring chains mounted too closely together influence each other
and generate invalid measuring results (cross talking effects). Measurements with the risk
of mutual influences are:
(2)
Non-linear range at the beginning of the total measuring range of the sensor, before the beginning of the linear measuring range.
(3)
Distance between sensor and zero point of the measuring range including initial air gap.
(4)
Current distance between zero position of the measuring range and measuring target.
