Precision Capacitive Sensors for Accurate Position Measurement

Non-contact Position Measurement with High Resolution over Short Ranges

Capacitive sensors from MicroSense offer the lowest noise performance of any commercially available capacitive sensor, achieving nanometer and even picometer resolution.  Several types of sensors are available - these "application specific" capacitive position sensors are optimized for either high stability and linearity or highest measurement bandwidth for fast response. 

All MicroSense® precision capacitive sensors feature:

  • Completely non-contact capacitive position measurement - the most accurate electrical sensing technology available
  • Detection of any conductive, grounded target – surface finish or material have no effect on accuracy
  • Optimized for short measurement ranges –10 micrometers up to 4 millimeters, depending upon sensor size
