Summary

Eddy-current probes require a minimum target area for calibration. Our precision calibration instruments have maximum target size limitations. The following parameters are provided to eliminate any additional tooling costs for calibration to custom targets.

Customer Supplied Targets

 

Cross-Sectional Area:

Probe DiameterMinimum:

The target surface being measured must fit a circle which is 3X the probe’s diameter 

Maximum:

Probes U3-U18: Height and Width Maximum – 3”, 75mm
Probes U25-U50: Height and Width Maximum – 6”, 150mm

Cross Section Area

 

 

 

 

 

Thickness:

Range: 1/16” – 1/8”, 1.5mm – 3mm

Curved Targets:

Curved targets must have a flat side for mounting against the calibrator’s actuator. For adequate target thickness, the edges must also be squared as shown in Figure 3. The cross-sectional area must still meet the requirements listed above.
