Capacitive Sensor Drivers CPL190 & CPL290 by Lion Precision

The Elite Series CPL190 and CPL290 capacitive sensor drivers from Lion Precision are high-resolution devices designed for demanding applications. The capacitive sensor modules have 1 to 8 sensing channels and can be configured for maximum flexibility.

Key Features:

The main features of the CPL190 and CPL290 capacitive sensor drivers are:

  • ±10 V output
  • Ranges available: 10 µm to 12.5 mm
  • 15 kHz bandwidth
  • 0.003% resolution at 15 kHz typical (RMS)
    • Probe/range dependent
    • Custom calibrations can achieve outstanding resolution performance
  • Small phase shift - excellent for servo applications
  • User selectable bandwidth for even higher resolutions (100 Hz, 1 kHz, 10 kHz)
  • Coarse/fine adjustable zero
  • Visual range indicator
  • Zero adjust disable
  • Switchable dual-range/sensitivity (CPL290)
  • Standard probes can be ordered as vacuum compatible
  • Single or multiple channel enclosures.
