Product Introduction
The Bently Nevada 330710-004-054-50-02-00 3300 XL 11 mm Proximity Probe is a high-performance, non-contact vibration and shaft-position sensor designed for continuous machinery condition monitoring. As part of the trusted 3300 XL family, it delivers precise displacement measurements by generating an eddy current field and detecting changes as the target surface moves. The probe is fully compliant with API 670 standards, making it ideal for demanding industrial environments such as power generation, petrochemical plants, and heavy manufacturing facilities where uninterrupted operation and early fault detection are critical.

FAQ
-
What type of target material provides the most accurate calibration?
AISI 4140 or similar carbon steel is recommended for the best measurement accuracy. -
How is electromagnetic interference minimized in this probe?
A coaxial cable design with integral shielding and grounded armor reduces external electrical noise. -
Can the probe perform reliably in environments with heavy vibration?
Yes, it is engineered to maintain stable measurements even in high-vibration industrial settings. -
What is the typical output impedance of the complete probe system?
Approximately 50 Ω when used with the specified extension cable and Proximitor driver. -
How does the probe maintain accuracy across varying temperatures?
Materials and internal compensation circuitry minimize thermal drift over the full operating range. -
Is it possible to use this probe with older Bently Nevada 7200 series drivers?
It is recommended to pair the 3300 XL probe with 3300 or 3500 drivers, though calibrated use with older drivers may be feasible. -
What is the recommended gap voltage for best linearity?
Typically around –10 VDC at the mid-gap position. -
Does the probe require recalibration if cable length changes?
Yes, the probe is factory-calibrated for its specified system length; any change in cable length requires recalibration. -
What level of moisture protection does the probe provide?
When properly installed, the assembly meets IP67 sealing requirements for reliable operation in wet or humid environments. -
What is the maximum static pressure rating at the probe tip?
The probe tip is rated for up to 2000 psi (137 bar).
