Bently Nevada Mechanical Monitoring and TSI Characteristics
The 330101 probe system operates based on high-frequency eddy-current sensing. Precise scaling is maintained at 7.87 V/mm (200 mV/mil) relative to the target material. During setup, gap voltage validation against a -10 VDC target at the mid-point of the linear range is necessary to ensure consistent output across the 0.25 mm to 2.3 mm linear span. To ensure accurate rotor dynamics analysis, installers must apply cross-talk suppression techniques by maintaining minimum physical separation between adjacent probes. Grounding of the coaxial cable shield must be consistent with the Proximitor sensor loop to prevent ground loops and high-frequency noise injection.
Frequently Asked Questions
Q: Is the 330101 probe compatible with legacy 3300 series Proximitor sensors?
A: No. The 330101 3300 XL probe is calibrated to match the specific impedance and frequency response of the 3300 XL Proximitor sensor. Use with older 3300 or 7200 series systems will cause non-linear output and calibration errors.
Q: What is the requirement for the ClickLoc connector during installation?
A: The ClickLoc connector provides a secure, vibration-resistant connection. It must be fully seated until a click is felt or heard to ensure reliable continuity in the coaxial path and to maintain the integrity of the signal shielding.
Field Installation Guidelines
- Ensure the mounting hole is drilled and tapped for 3/8-24 UNF-2A threads, maintaining perpendicularity to the shaft surface.
- Carefully install the probe into the mounting bracket or sleeve. Avoid using excessive force that could damage the probe tip or the threaded housing.
- Once the probe is positioned to the desired gap, secure the jam nuts using a torque value consistent with standard industrial mounting practices to prevent loosening.
- Route the coaxial cable through shielded conduit, ensuring the cable is not pulled tight or subjected to sharp bends that exceed the minimum bend radius.
- Validate the output voltage using a high-impedance digital multimeter at the Proximitor sensor terminals to ensure the gap is set correctly before machine startup.
