Bently Nevada 330909-00-50-10-01-05 – Eddy Current Proximity Probe | 3300 NSv Platform
The Bently Nevada 330909-00-50-10-01-05 is a high-precision eddy current proximity probe engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. As a core sensing element of the 3300 NSv (Non-contacting Vibration) System, this probe delivers the measurement accuracy and long-term reliability demanded by power generation, petrochemical, and heavy industrial applications.
Procurement engineers specify this probe for API 670-compliant machinery protection systems where measurement integrity and system interoperability are non-negotiable.

System Architecture & Signal Flow
The 330909-00-50-10-01-05 operates as the field-sensing element in a three-component eddy current measurement chain:
- Probe (330909-00-50-10-01-05) — generates oscillating electromagnetic field; detects target displacement via impedance change
- Extension Cable (330130 series) — transmits raw probe signal with minimal loss over distances up to 9 m total system length
- Driver / Proximitor (3300 XL 8mm or NSv Driver) — conditions signal, outputs –24 VDC bias and 200 mV/mil proportional voltage to monitoring system
Total system cable length (probe + extension) must not exceed the driver’s rated specification. Verify driver part number compatibility before ordering extension cables.

Technical FAQ
Q: Is the 330909-00-50-10-01-05 compatible with the older 3300 XL 8mm driver?
A: The 3300 NSv probe series is designed for NSv drivers. Cross-compatibility with 3300 XL drivers requires verification of driver firmware version and system configuration. Contact our engineering team for a compatibility assessment.
Q: Can this probe measure non-ferromagnetic targets (e.g., titanium, aluminum)?
A: Yes, but sensitivity and linear range will differ from the standard AISI 4140 calibration. A target-specific calibration factor must be applied. Bently Nevada provides calibration data for common non-standard target materials.
Q: What is the maximum operating temperature for the cable jacket?
A: The integral cable is rated to +177°C. For higher ambient temperatures at the cable routing path, specify a high-temperature extension cable (330130-XX-XX series).
Q: Do you supply the complete 3300 NSv measurement chain (probe + extension + driver)?
A: Yes. Konmask.com stocks the full 3300 NSv component set. Contact us with your system BOM for a consolidated quotation.
