Installation and Compatibility

The 330901-00-65-05-02-05 probe should be installed according to the standard mounting procedures for Bently Nevada 3300 XL series. It must be connected to a matching 3300 XL Proximitor sensor and extension cable, maintaining the factory-calibrated system length.

Installation Steps:

1. Thread the probe into the machine housing until the tip is approximately 1 mm from the target surface.

2. Torque the probe to 2.26 N·m.

3. Route the cable through protective conduits to avoid sharp bends or abrasion.

4. Connect to the extension cable and then to the proximitor sensor.

5. Verify the system length and perform system calibration check using a static calibration fixture.

Compatible Components:

• 3300 XL Proximitor Sensor (e.g., 330180 or 330980 series)

• 3300 XL Extension Cable (length-dependent)

• Monitoring Systems: Bently Nevada 3500, 3701 series

FAQ(Frequently Asked Questions)

Q1: What type of monitoring system is this probe compatible with?

A1: This probe is fully compatible with the Bently Nevada 3500 and 3701 machinery monitoring systems when used with the 3300 XL Proximitor sensor and extension cable.

Q2: Can I cut or shorten the cable on this probe?

A2: No. The cable is part of a calibrated system length. Altering the cable will affect accuracy and void the calibration.

Q3: What is the difference between 330901 and 330103 part numbers?

A3: The 330901 series is an 8 mm proximity probe, while the 330103 series is typically used in shorter-length or non-API configurations.

Q4: Is the probe suitable for hazardous locations?

A4: Yes, when used with certified proximitor sensors and installed in accordance with local hazardous location standards (ATEX, CSA, etc.).

Q5: What is the recommended distance from the target surface?

A5: The probe should be installed with a 1.0 mm gap to ensure optimal linear performance.

Q6: What is the expected service life of the probe?

A6: The probe can last over 5+ years under normal industrial conditions with proper installation and no physical damage.

Q7: How do I check if the probe is working correctly?

A7: Use a Bently Nevada test fixture or dial indicator to verify the probe’s linearity and sensitivity.

Q8: Can I replace just the probe without changing the Proximitor?

A8: Only if the new probe is of the exact same model and system length; otherwise, recalibration is necessary.

Q9: Is shielding required for the cable?

A9: The cable has built-in EMI shielding but should still be routed away from high voltage sources.

Q10: Can this be used for thrust position monitoring?

A10: Yes, it is often used for both radial vibration and axial thrust position measurements.
