3.7 Measurement of Disk Eccentricity

3-20
Advantages of Using the K3HB-S
• The peak-to-peak hold function can be used for simple
eccentricity measurement by measuring the difference between
the maximum and minimum values for linear sensor signals that
change continuously.
• Measurements are taken during the timing input (pushbutton
switch in diagram) is ON and the last result is held when it is OFF.
• Applications such as measuring shaft eccentricity are possible.
(Similar applications are possible for non-metallic objects using an
ultrasonic displacement sensor.)
