Develop an ac bridge for given Problem. Use 880 pF for all the bridge capacitors, and assume a 10-V rms, 10-kHz excitation. What is the maximum bridge offset voltage amplitude?
Problem
A capacitive displacement sensor is used to measure rotating shaft wobble, as shown in given Figure. The capacity is 880 pF with no wobble. Find the change in capacity for a + 0.02 to -0.02-mm shaft wobble.
