Bently Nevada 330104-10-20-10-02-CN 3300 XL Proximity Probe

Bently Nevada 330104-10-20-10-02-CN 3300 XL Proximity Probe

The Bently Nevada 330104-10-20-10-02-CN, also cataloged as the 330104 Proximity Probe, operates as a dedicated hardware component for static position and dynamic vibration measurements within machinery monitoring systems. It functions as part of the 3300 XL 8 mm Proximity Transducer System, producing an output voltage directly proportional to the physical gap between the probe tip and the observed conductive target surface.

Hardware Specifications

Proximity Transducer Mechanical Monitoring Attributes

The 3300 XL 8 mm system requires strict gap voltage validation to maintain standard eddy-current probe scaling across the full linear range. Field technicians execute verification protocols targeting -10 VDC at the physical center point of the measurement gap to secure linear calibration. This precise mechanical positioning minimizes errors in rotor dynamics assessment and optimizes cross-talk suppression when multiple transducer probes are clustered in close proximity around the shaft area.

Frequently Asked Questions

Q: Does this probe require matching or bench calibration with specific system cables?

A: No. All 3300 XL 8 mm hardware components feature complete cross-component interchangeability, allowing replacement of probes, cables, or sensors without re-calibration.

Q: Can this 3300 XL component be used with older, non-XL 3300 transducer systems?

A: Yes. The hardware is backward compatible and interchangeable with standard non-XL 3300 series 5 mm and 8 mm transducer components.

Field Installation Guidelines

Ensure the installation housing matches the specific reverse-mount or threaded physical envelope of the probe body to prevent mechanical distortion. Thread the probe into place while tracking output voltage until reaching the standard -10 VDC gap setting on a calibrated voltmeter. Secure the outer locknuts according to specified industrial limits to prevent loosening from machinery vibration, and protect all coaxial junctions inside an environmental conduit to prevent fluid contamination.
