Description

Precise, High-Speed Measurements

  • High Resolution
    • 0.003% @ 15 kHz typical (as low as 0.25 nanometers)
    • 0.0005% @ 100 Hz typical (as low as 0.05 nanometers)
    • Probe/Range dependent, see Probes and Ranges below for specifics
  • User selectable bandwidth filters (100 Hz, 1 kHz, 10 kHz, unfiltered)
  • Linearity: 0.2%, Typical
  • 15 kHz Bandwidth
  • Small phase shift – excellent for servo applications

Convenient Output Interface and Range Selections

  • Measurement Ranges Available: 10 µm to 12.5 mm
  • Switchable Dual-Range/Sensitivity (CPL290 only)
  • ±10 V Output
  • Easy National Instruments DAQ Connection via 68-Pin connector

* Resolution values are RMS. Peak-to-peak values are typically 8-10 times greater than the RMS values. Read Understanding Sensor Resolution Specifications and Effects on Performance about this often misunderstood specification.
In high EMI conditions (10 V/m), output DC level may shift and noise may rise to 0.2 VRMS (1% resolution)
Custom calibrations can achieve exceptional resolution performance
