Product overview
YD-20 is a portable calibrator for field or laboratory use. It is intended for static-characteristic calibration of eddy current displacement sensors and calibration of the displacement instruments used with those sensors.
Calibration ranges and target material
| Parameter | Specification |
|---|---|
| Calibration ranges listed | 0–25 mm; 0–35 mm; 0–50 mm |
| Accuracy entry | Refers to dial-indicator accuracy specifications but gives no numerical accuracy |
| Target material | 40CrMoA |
Target-disc and maximum-probe pairings
| Target-disc diameter | Maximum probe diameter |
|---|---|
| φ75 mm or φ105 mm | φ25 mm |
| φ105 mm or φ125 mm | φ35 mm |
| φ150 mm or φ175 mm | φ50 mm |
Accuracy limitation
The catalog heading says calibration accuracy, but its content supplies a dial-indicator reference and calibration ranges only. A range is not an accuracy specification, and numerical accuracy cannot be inferred from the mention of a dial indicator.
