Functional Characteristics
The probe uses an eddy‑current sensing principle to detect the distance between the probe tip and a conductive target, typically a rotating shaft. The 3300 XL design improves temperature stability, linearity, and long‑term drift performance compared to earlier 3300 series probes.
Backward compatibility allows the 330101‑33‑53‑10‑02‑05 to replace older 5 mm or 8 mm non‑XL probes without modifying existing mounting hardware or system calibration, making it ideal for retrofit applications.
Applications
-
Turbomachinery vibration monitoring
-
Shaft position and radial displacement measurement
-
Phase reference and speed measurement
-
Compressors, turbines, pumps, and industrial rotating equipment
-
Hazardous‑area installations requiring certified components
FAQ
Q: Can this probe be used with older 3300 drivers? A: Yes. The probe is fully backward‑compatible with non‑XL 3300 series drivers and extension cables.
Q: Is the cable replaceable? A: No. The probe cable is factory‑molded to maintain shielding integrity and measurement accuracy.
Q: What environments is this probe certified for? A: It carries CSA, ATEX, and IECEx approvals for hazardous industrial zones.
