Eddy-Current Sensors
ECL202 & ECL202e Eddy-Current Sensor: Probes and Ranges
Description
| Standard Ranges | Fine Ranges
Probe model numbers are specified by their diameter and body style: i.e. a U8C probe has an 8mm diameter and a "C" body style.
Probe diameter determines the range.
Larger Diameter = Larger Range
See the probe page for mechanical details, important mounting clearances, and temperature limits.
Probes can be ordered as vacuum compatible.
Ranges and Resolutions
Standard Range and Fine Range options are available.
A specific range and resolution will require a particular probe size/model. Range/Resolution may also be affected by the target material. "Standard" and "Fine" ranges are available for probes U3-U12. The Fine range has a smaller range but better resolution and are not available for the ECL202e.
Custom ranges are always available.
Listed specifications are for standard target materials.
Because of high resolutions, exports of the ECL202 may require an export license. The ECL202e has different resolution specifications and can ship without export license delays.
Specifications assume a target area at least 3 times the diameter of the probe.
