Nanopositioning Sensor – NanoSensor for the ultimate in position monitoring
The NanoSensor® is a non-contact position measuring system based on the principle of capacitance micrometry. Two sensor plates, a Target and a Probe, form a parallel plate capacitor.
The spacing of these two plates can be measured using the appropriate electronic controller, to better than 7pm, with a range up to 1.25mm, a frequency response up to 10KHz and linearity down to 0.02%. Because the NanoSensor is a non-contact method, it is free from hysteresis. No power is dissipated at the point of measurement.
