Overview
The ECS98 family of single channel and differential eddy-current proximity sensors are instrument-grade position sensors for precision measurement, ideal for academic laboratories. The sensors enable researchers to detect
- position
- displacement
- alignment
- vibration
- non-conductive coatings
- films
- cracks
- wear
- strain
Full-scale position ranges are 1, 2, and 4mm with the standard 5, 10, and 20mm probes respectively. The full-scale position changes are converted to a ± 10V via low-noise electronics. Custom probes are also frequently provided for OEM and research applications.
In most cases, a linear output is achieved by restricting the measurement, but the use of external software linearization is common. Factory provided linearization formulas are available upon request.
The sensor operates on a single 12-15 V supply, has high power supply rejection ratio, and has reduced sensitivity to probe cable flexure relative to competing designs. Resolutions of 10 Angstroms are common in temperature-stable environments.
