Theamount of capacitance depends on the distance and material between the two conductors. A capacitive sensor uses an electric fieldto measure changes of capacitance between the probe surface and a conductive target surface.Conductive TargetsIf the material between the two conductive surfaces remains constant, any change in capacitance is due to a change in the distancebetween them. Capacitive sensors are calibrated to produce a repeatable output for a given change in distance between the probeand the target. This technique works over small ranges (10 µm - 12 mm) with resolutions as low as 0.06 nm.Nonconductive TargetsCapacitance also depends on the material between the probe and a conductive target surface. If the distance between the probe anda target surface is fixed, capacitive sensors can measure changes in the material between them. This technique is traditionally used todetect changes in thickness, density, or volume of material, but could also detect changes in material composition.Maximizing AccuracyAccuracy at the high resolutions of capacitive sensors may be greatly affected by the environment and measurement setup. Probesmust be positioned in a stable mechanical system in a stable environment. Even small changes in temperature cause expansions ofthe target that are detectable by high-resolution capacitive sensors. These are not sensing errors; the displacements are real.ResolutionResolution is a measurement system’s smallest possible measurement. Resolution is essentially a measurement of electrical noisepresent at the sensor output. Capacitive sensor resolution is a function of the bandwidth of the system. The lower the bandwidth, thebetter the resolution. When comparing specifications, be sure you know the bandwidth at which the resolution is specified.See the complete capacitive sensor tutorial TechNote and a detailed article on sensor resolution at:www.lionprecision.com; click on Technical Library.2Lion Precision • 563 Shoreview Park Road • St. Paul, MN 55126 • USA • 800-229-6544 • 651-484-6544Capacitive Sensors
