Non contact capacitive displacement sensor
± 25 - ± 1 000 µm | 5810 series MicroSense, LLC

The MicroSense Model 5810 is a single channel, non-contact precision capacitive displacement sensor. Designed for high dynamic applications, the Model 5810 provides high resolution with measurement bandwidth up to 100 kHz

Ideal for non-contact displacement measurement and dimensional measurement over short ranges, from ± 5 micrometers up to ± 0.5 millimeters.
Reliably measure even poorly grounded targets such as air bearing spindles and motors.
High resolution - nanometer and sub-nanometer resolution is possible. Resolution is determined by sensor size, range and measurement bandwidth.
Use with any grounded, conductive target - material or surface finish has no effect on accuracy
Selectable measurement bandwidth - 1, 5, 20 or 100 kHz.
