Capacitec supplies non-contact capacitive hole diameter probes by installing two, three, four or more non-contact capacitive displacement sensor around a circular metal probe. In conjuction with Capacitec amplifiers these hole diameter sensor probes can obtain accuracies of 0.1% FS and resolutions of 0.02% FS
When the Capacitec Bragrafx software is added, the profile of the hole or bore diameter can be shown along multiple points along the bore length.
