System Architecture & Signal Flow
The 32000-28-05-15-080-03-02 assembly operates as part of a three-component eddy-current system:
- Proximity Probe (this assembly) – Generates a high-frequency electromagnetic field; detects shaft surface displacement via eddy-current effect
- Extension Cable – Transmits the raw oscillator signal from probe tip to driver with minimal signal loss
- Proximitor® Driver / Oscillator-Demodulator – Converts the raw signal to a calibrated DC voltage proportional to gap distance, fed to the 3300 XL monitor
The monitor then processes the signal for vibration amplitude, phase, and DC gap, triggering alarms or shutdowns per configured setpoints.

Technical FAQ
Q: Is this assembly compatible with the Bently Nevada 3300 XL monitor?
A: Yes. The 32000-28-05-15-080-03-02 is designed for direct use within the 3300 XL system architecture, maintaining full signal chain compatibility.
Q: Does this require a separate Proximitor driver?
A: Yes. The probe assembly requires a compatible Bently Nevada Proximitor® oscillator-demodulator (sold separately) to produce the calibrated output voltage.
Q: Can this probe be used on non-ferrous target materials?
A: The standard calibration is optimized for AISI 4140 steel. Use on non-ferrous targets (aluminum, titanium) requires recalibration — contact our technical team for guidance.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, lead time is typically 2–4 weeks. Contact us for current availability.
Q: Do you provide a warranty?
A: Yes. All units carry a 90-day functional warranty covering manufacturing defects. Extended warranty options are available on request.
