ECD140 Eddy-Current Displacement Sensor for CompactRIO (National Instruments)

The ECD140 plugs directly into a National Instruments
CompactRIO system for instant use with LabVIEW.

Performance

• Linearity: ±0.2%
• Resolution: 0.002-0.025% F.S.
  (see Probes and Ranges for details)
• Bandwidth: 15 kHz

Features

• Front Panel Indicator for Easy Setup
• Plugs into NI CompactRIO systems
• Instant LabVIEW Accessibility

Life-Cycle Status: Active

Export Requirements

Because of high resolutions, exports of the ECD140 may require an export license. The ECD141 has different resolution specifications and can ship without export license delays.

LabVIEW, CompactRIO Drivers

Firmware Version	Demo Files	Manual
Rev 2	ECD14x-Basic-Rev-2.zip (0.8M) ECD14x-Multi-Chan-Demo-Rev-2.zip (1.8M)	ECD140 Manual Rev 1 (250K pdf)

Intended Users

The ECD140 is intended for LabVIEW users experienced in FPGA and Real Time processor programming on the RIO platform. The device and the included software provide a tool kit for developers creating a complete system which requires precision noncontact displacement sensors. The system is not intended to be out‑of‑the‑box operational, but requires implementation and programming by experienced LabVIEW FPGA users.

Specifications

Typical specifications for standard targets and probes. Actual values depend on probe, target, and calibration.
