System Architecture & Signal Flow
The 330103-03-09-10-02-00 operates as a three-component eddy-current proximity measurement system:
- Probe (330103-xx) – Generates a high-frequency electromagnetic field (~1 MHz) directed at the rotating shaft target. Changes in air gap modulate the field amplitude proportionally.
- Extension Cable (330130-xx) – Low-loss coaxial cable transmitting the modulated RF signal from probe to proximitor. Total system cable length is a calibration parameter — do not substitute with non-matched cables.
- Proximitor / Oscillator-Demodulator (330180-xx) – Demodulates the RF signal and outputs a DC-coupled voltage proportional to gap distance at 200 mV/mil. Output feeds directly to Bently Nevada 3500 or 3300 series rack monitors.
Signal path: Shaft gap → Probe → Extension Cable → Proximitor → Monitor Rack (3500/3300) → DCS / PLC / SCADA

Technical FAQ
Q: Is the 330103-03-09-10-02-00 compatible with a Bently Nevada 3500 rack?
A: Yes. The 3300 XL proximity system is fully compatible with 3500 series monitors. Verify that the proximitor output range matches the monitor input card specification before installation.
Q: What is the difference between the 330103 and 330104 probe series?
A: The 330103 uses a 3/8–24 UNF thread and 8 mm tip diameter; the 330104 uses a 1/4–28 UNF thread and 5 mm tip. Selection depends on the probe boss geometry machined into the bearing housing.
Q: Can I substitute a different extension cable length?
A: No. Total system cable length (probe integral + extension) is a calibration parameter. Substituting a non-matched cable length will shift the scale factor and linear range, requiring full system re-calibration by a qualified technician.
Q: Is this part RoHS compliant?
A: Yes. The 330103-03-09-10-02-00 meets RoHS Directive 2011/65/EU requirements.
Q: What warranty is provided?
A: All units carry a 90-day functional warranty against defects in materials and workmanship. Extended warranty options are available — contact us for details.
