Precision Capacitive Sensor – Model 6810 - Capacitive Position Sensors
The Model 6810 high-resolution capacitive sensor offers state-of-the-art performance for position and displacement measurement. The 6810 is designed specifically for "high dynamic" measurement of high speed rotating or oscillating targets such as precision Hard Disk Drive spindle motors, precision air bearing spindles and mechanical bearing machine tool spindles. Applications include run out measurements such as axial and radial NRRO (non-repeatable runout or asynchronous error motion) which require resolution of 1 to 2 nm-rms or better.
