Bently Nevada 330904-00-02-05-01-00 Proximity Probe – 3300 XL 8mm Eddy Current Transducer System
When a critical rotating machine loses its shaft vibration monitoring capability, the consequences are immediate and severe: undetected rotor imbalance, bearing wear, or shaft misalignment can escalate within minutes into catastrophic machinery failure, unplanned downtime, and six-figure repair costs. In high-stakes environments such as gas turbines, steam turbines, centrifugal compressors, and large pumps, continuous proximity measurement is not optional — it is the last line of defense between normal operation and a plant-wide emergency shutdown. A single missing or failed proximity probe can render an entire machinery protection system blind.
The Bently Nevada 330904-00-02-05-01-00 is an 8mm eddy current proximity probe engineered as part of the industry-standard 3300 XL 8mm Proximity Transducer System. Within the 3300 Series family, this model delivers a sensitivity of 200 mV/mil (7.87 V/mm) with a linear measurement range of 0–80 mil (0–2.03 mm), making it the preferred choice for shaft radial vibration, axial position, and differential expansion monitoring. Trusted by rotating equipment engineers across power generation, oil & gas, and petrochemical facilities worldwide, the 3300 XL Series remains the de facto standard for API 670-compliant machinery protection systems.

Frequently Asked Questions
- Q: Is the 330904-00-02-05-01-00 compatible with older 3300 Series systems?
- A: Yes. The 3300 XL 8mm probe family maintains backward compatibility with earlier 3300 Series extension cables and proximitors, provided the cable length configuration matches the system calibration curve.
- Q: What is the difference between the 330900 and 330904 probe series?
- A: The 330904 series features an extended temperature rating and enhanced EMI shielding compared to the base 330900 series, making it better suited for high-temperature turbine and compressor environments.
- Q: Can this probe be used for axial position measurement?
- A: Yes. With appropriate mounting hardware and a compatible proximitor, the 330904-00-02-05-01-00 can be configured for both radial vibration and axial position (thrust) measurement applications.
