FAQ
-
How does the 3300 XL 11 mm Proximity Probe measure shaft vibration?
It uses eddy-current sensing, generating a magnetic field and detecting changes as the conductive shaft moves, converting these into a precise electrical signal. -
What is the recommended gap voltage for correct operation?
The probe typically operates at a –8 V DC gap voltage when set at the specified target distance, ensuring linear measurement response. -
Which Proximitor drivers are supported?
It is designed to work with the Bently Nevada 3300 XL series Proximitor drivers for accurate signal conditioning and system calibration. -
What is the maximum vibration level it can tolerate?
The probe withstands up to 100 g peak vibration across 10–2000 Hz without affecting measurement accuracy. -
Is the probe sensitive to oil films on the shaft surface?
No, the eddy-current technology maintains reliable output even when a thin oil film is present between the probe and the target. -
What is the frequency response / the probe-driver system?
It provides a flat frequency response from DC up to 10 kHz, suitable for high-speed rotating machinery monitoring. -
Does it require special shielding against electromagnetic interference?
No additional shielding is needed beyond normal installation practices, as the probe incorporates built-in EMI/RFI protection. -
How is calibration maintained over time?
Calibration remains stable if the probe, extension cable, and Proximitor driver are used as a matched set and handled according to installation guidelines. -
Can the probe be used for both radial and axial measurements?
Yes, it is suitable for radial shaft vibration as well as axial (thrust) position monitoring when correctly mounted. -
What is the insulation resistance requirement?
The probe maintains an insulation resistance greater than 100 MΩ at 500 V DC, ensuring reliable electrical isolation in high-voltage environments.
