- Probes can be ordered as vacuum compatible.
Life-Cycle Status: Active
Export Requirements
Because of high resolutions, exports of the ECD140 may require an export license.
ECD140e
The ECD140e has different resolution specifications and can ship without export license delays.

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. Specifications assume a target area at least three times the diameter of the probe.
