Bently Nevada 330903-00-08-05-01-00 – High-Precision Proximity Transducer System | 3300 XL NSv Platform
Engineering Background: The Bently Nevada 3300 XL NSv (Non-contacting Vibration) Proximity Transducer System is a cornerstone of rotating machinery protection in critical industrial environments. Engineered to API 670 standards, this system delivers continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion — enabling real-time machinery health monitoring without mechanical interference.
Product Positioning: Part number 330903-00-08-05-01-00 is a complete NSv transducer assembly configured for 8 mm probe tip diameter, 5-metre extension cable, and standard 1-metre armored cable. It is the preferred choice for procurement engineers specifying replacement or expansion components within existing Bently Nevada 3300 XL monitoring architectures on turbines, compressors, pumps, and gearboxes.

Engineering Advantages
- Non-contact measurement eliminates mechanical wear and enables continuous online monitoring
- API 670 compliant — meets the most stringent machinery protection specifications in the industry
- Wide frequency response (DC–10 kHz) captures both slow-roll runout and high-frequency vibration events
- Armored cable construction resists oil, chemical splash, and mechanical abrasion in harsh plant environments
- Direct drop-in replacement for existing 3300 XL NSv installations — no recalibration of the monitoring rack required
- Stable thermal performance across wide temperature range ensures accuracy in hot-section and cold-climate installations
System Architecture & Signal Flow
The 330903-00-08-05-01-00 operates as a three-component eddy-current system:
- Probe (330903 series) — generates a high-frequency electromagnetic field directed at the rotating shaft target
- Extension Cable — transmits the RF signal between probe and driver with minimal loss over 5 m
- Driver / Oscillator-Demodulator — converts the impedance change caused by shaft proximity into a DC voltage output proportional to gap distance
The DC output feeds directly into a Bently Nevada 3300 XL monitor card, which performs alarm, danger, and trip logic in accordance with the configured setpoints. The system is fully compatible with Bently Nevada System 1 software for trend analysis and predictive maintenance workflows.

Technical FAQ
Q: Is this unit compatible with the Bently Nevada 3300/16 monitor card?
A: Yes. The 330903-00-08-05-01-00 is fully compatible with all 3300 XL series monitor cards, including the 3300/16, 3300/20, and 3300/25 models, provided the driver gap voltage is within the –10 V to –18 V linear range.
Q: Can this transducer be used on non-steel shaft targets?
A: The standard calibration is optimized for AISI 4140 steel. For Inconel, titanium, or other alloys, a target material correction factor must be applied. Contact our engineering team for recalibration guidance.
Q: What is the shelf life of an unused unit?
A: Bently Nevada proximity transducers have an indefinite shelf life when stored in original packaging in a dry, temperature-controlled environment (15–30 °C, <60% RH). We recommend a functional verification test before installation if stored more than 3 years.
Q: Do you provide installation and commissioning support?
A: Konmask provides remote technical support for installation gap-setting, driver output verification, and monitor card configuration. On-site commissioning services can be arranged through our partner network.
Q: Is an export license required for this product?
A: This product is classified as industrial instrumentation (EAR99 / ECCN N/A for most destinations). Konmask handles all export documentation. Buyers in restricted jurisdictions should confirm compliance requirements with their trade compliance team.
