Engineering Advantages
- NSv Technology: Non-contacting, wear-free measurement eliminates sensor degradation over time, reducing maintenance intervals and lifecycle cost.
- Wide Frequency Bandwidth: 0–10 kHz response captures sub-synchronous, synchronous, and high-frequency vibration components for comprehensive spectral analysis.
- High Temperature Tolerance: Probe rated to +177°C enables direct installation in high-heat zones without thermal isolation hardware.
- Plug-and-Play Compatibility: Direct replacement for existing 3300 XL installations — no recalibration of monitoring system required when replacing like-for-like.
- Robust Construction: Stainless steel probe body with hermetically sealed tip resists oil, steam, and chemical ingress in demanding process environments.
- Long-term Signal Stability: Factory-calibrated sensitivity of 200 mV/mil maintained across full operating temperature range.
System Architecture & Signal Flow
The 330904-00-21-50-02-00 operates as part of a three-component eddy current system:
- Probe (330904 series): Generates oscillating electromagnetic field; detects target proximity via impedance change.
- Extension Cable: Transmits high-frequency signal from probe to driver with minimal loss; matched impedance to probe.
- Proximitor® Driver (3300 XL NSv): Conditions raw signal into calibrated DC voltage output; interfaces directly with 3500/3300 series monitor cards.
Output voltage feeds directly into Bently Nevada 3500 rack monitor inputs or legacy 3300 monitor cards, enabling seamless integration into existing machinery protection architectures.
Sourcing & Quality Verification

Technical FAQ
Q: Is the 330904-00-21-50-02-00 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 3300 XL NSv transducer system outputs a standard -24 VDC-powered, voltage-output signal fully compatible with 3500 series monitor input cards.
Q: Can this transducer be used on non-steel targets?
A: The standard calibration is for AISI 4140 steel. For other target materials (Inconel, titanium, etc.), a material correction factor must be applied. Contact our engineering team for recalibration guidance.
Q: What is the shelf life of an unused unit?
A: Properly stored in original packaging at controlled temperature and humidity, Bently Nevada proximity transducers maintain specification for a minimum of 5 years from manufacture date.
Q: Do you provide certificates of conformance?
A: Yes. A certificate of conformance and available factory test documentation are provided with every order upon request.
Q: What is your lead time for this part number?
A: Standard lead time is 3–7 business days for in-stock units. Express dispatch available for urgent requirements — contact us to confirm current stock status.
