FAQ
-
How does the 3300 XL 11 mm Proximity Probe sense shaft movement?
It operates on the eddy-current principle, producing a magnetic field and detecting changes in impedance as the shaft moves, converting these variations into a proportional electrical signal. -
What is the recommended gap voltage for correct operation?
A typical operating gap voltage / around –8 V DC ensures linear output and accurate displacement measurement. -
Which Proximitor drivers are compatible with this probe?
It is fully compatible with Bently Nevada 3300 XL Proximitor drivers, ensuring accurate signal conditioning and calibration. -
What vibration levels can the probe withstand?
The probe endures vibration up to 100 g peak within the 10–2000 Hz range without affecting measurement accuracy. -
Is the measurement affected by an oil film on the shaft?
No, the eddy-current technology maintains accuracy even when a thin oil film is present between the probe and target surface. -
What is the frequency response / the probe-driver system?
The system provides a flat frequency response from DC to 10 kHz, suitable for monitoring high-speed rotating equipment. -
Does the probe require extra shielding for electromagnetic interference?
No additional shielding is necessary; the probe’s design includes integrated EMI/RFI protection for stable operation. -
How is calibration maintained over time?
Calibration remains stable as long as the probe, extension cable, and Proximitor driver remain a matched set and are installed per Bently Nevada guidelines. -
Can the probe measure both radial and axial displacement?
Yes, it is suitable for both radial shaft vibration monitoring and axial (thrust) position measurement when installed correctly. -
What insulation resistance is required for reliable performance?
The probe maintains insulation resistance greater than 100 MΩ at 500 V DC, ensuring dependable electrical isolation.
