Basics

When two conductive surfaces are near each other, there is an electrical property called capacitance that exists between them. The amount of capacitance depends on the distance and material between the two conductors. A capacitive sensor uses an electric field to measure changes of capacitance between the probe surface and a conductive target surface.

Conductive Targets

If the material between the two conductive surfaces remains constant, any change in capacitance is due to a change in the distance between them. Capacitive sensors are calibrated to produce a repeatable output for a given change in distance between the probe and the target. This technique works over small ranges (10 µm - 12 mm) with resolutions as low as 0.05 nm.

Nonconductive Targets

Capacitance also depends on the material between the probe and a conductive target surface. If the distance between the probe and a target surface is fixed, capacitive sensors can measure changes in the material between them. This technique is traditionally used to detect changes in thickness, density, or volume of material, but could also detect changes in material composition.

Maximizing Accuracy

Accuracy at the high resolutions of capacitive sensors may be greatly affected by the environment and measurement setup. Probes must be positioned in a stable mechanical system in a stable environment. Even small changes in temperature cause expansions of the target that are detectable by high-resolution capacitive sensors. These are not sensing errors; the displacements are real.

Resolution

Resolution is a measurement system’s smallest possible measurement. Resolution is essentially a measurement of electrical noise present at the sensor output. Capacitive sensor resolution is a function of the bandwidth of the system. The lower the bandwidth, the better the resolution. When comparing specifications, be sure you know the bandwidth at which the resolution is specified.

Standard cable length: 2 meters. Operating and storage temperature range: 4-50 °C. Available as vacuum compatible. Probes are not electrically damaged by contact with the sensing tip. Range is determined by the probe Sensing Area diameter — the larger the diameter, the larger the range. To hold specifications, flat target surface diameter must be 1.3 times larger than sensing area diameter. Measurement Ranges and other performance specifications are dependent on the selected driver model. Different probe body styles/sizes are available for each sensing area diameter.

Probe Model NumbersProbe model numbers are a combination of the Body Model number and Sensing Area Diameter in mm (e.g. C5S-0.8 or R45-19).
