Bently Nevada 330103-00-08-50-02-00 – 8mm Proximity Transducer | 3300 XL Series Platform
Engineering Background: The Bently Nevada 3300 XL Proximity Transducer System is the industry benchmark for non-contact, continuous shaft vibration and position measurement in rotating machinery. Engineered to API 670 standards, this system is deployed globally in critical turbomachinery protection and condition monitoring applications where measurement accuracy and system reliability are non-negotiable.
Product Positioning: The 330103-00-08-50-02-00 is an 8mm eddy-current proximity transducer configured with a 5-metre extension cable and standard 3300 XL driver. It delivers high-resolution radial vibration, axial position, and differential expansion data to DCS/PLC safety systems and condition monitoring platforms. Ideal for procurement engineers sourcing certified replacement or expansion components for existing 3300 XL installations.

- Plug-and-play 3300 XL compatibility: Direct replacement for existing installations; no recalibration of the monitoring rack required when using matched system components
- High EMI immunity: Shielded cable and driver design reject electrical noise in industrial environments
- Proven field reliability: Millions of operating hours across global critical infrastructure
System Architecture & Signal Flow
The 330103-00-08-50-02-00 operates as a three-component eddy-current system:
- Probe (330103): Generates a high-frequency electromagnetic field at the probe tip. Gap changes between probe and conductive target modulate eddy-current losses.
- Extension Cable (330130 / 5 m): Transmits the RF signal between probe and driver with controlled impedance. Cable length is factory-matched to the driver for calibration accuracy.
- Driver / Oscillator-Demodulator: Converts the modulated RF signal into a DC-proportional voltage output (–2 V to –18 V). Output feeds directly to 3300 XL monitor input cards or compatible DCS/SIS systems.
Signal output is linear across the specified gap range and is directly compatible with Bently Nevada 3500 series monitors and third-party systems accepting –24 VDC-powered proximity inputs.

Technical FAQ
Q: Is this part compatible with the Bently Nevada 3500 monitoring system?
A: Yes. The 3300 XL proximity transducer system is electrically compatible with 3500 series monitor input cards when using the correct driver. Confirm driver compatibility with your 3500 rack configuration before ordering.
Q: Can the extension cable length be changed?
A: Extension cable length is factory-matched to the driver for calibration. Changing cable length requires a matched driver recalibration. Contact us if a non-standard cable length is required.
Q: What target materials are supported?
A: Standard calibration is for AISI 4140 steel. Other alloys (stainless steel, titanium, Inconel) require target material correction factors or custom calibration. Consult Bently Nevada application notes or contact our engineering team.
Q: Do you provide calibration certificates?
A: Calibration certificates from the original manufacturer are provided where available. Third-party calibration can be arranged on request.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock inquiries, typical lead time is 2–4 weeks. Contact us for real-time availability.
