155 An example of an ECT differential signal response
The differential configuration is widely employed to connect air conditioner (A/C)
probes. Differential configurations are also used in cross-axis coil probes, which are
used to inspect copper finned tubes in air conditioner units. Although not illustrated
here, cross-axis coil probes are used in a similar way as A/C probes, but they typically
require 10 dB to 20 dB more gain than A/C probes, and a 100 Hz low-pass (LP) filter.
Figure 5-156 on page 232 shows an example of an A/C probe. Figure 5-156 on
page 232 shows an example of signals from an A/C probe’s pancake coils.
