===Machine tool metrology===

Capacitive displacement sensors are often used in metrology applications. In many cases, sensors are used “to measure shape errors in the part being produced. But they also can measure the errors arising in the equipment used to manufacture the part, a practice known as machine tool metrology”.<ref name="LLNL">[https://www.llnl.gov/str/Blaedel.html Lawrence Livermore National Laboratory: Engineering Precision into Laboratory Projects], Examples of advances made by LLNL in the field of precision measurement.</ref> In many cases, the sensors are used to analyze and optimize the rotation of spindles in various machine tools, examples include [[surface grinder]]s, [[lathe]]s, [[milling machine]]s, and [[air bearing]] spindles.<ref name="PrecisionSpindleMetrology">{{cite book|isbn=978-1-60595-003-37|title=Precision Spindle Metrology|author=Eric R.
