System Architecture & Signal Flow
The 330104-02-25-10-02-00 system comprises three matched components operating as a calibrated unit:
- Probe (330104 series): Eddy-current sensing element installed at the shaft measurement point. Generates a high-frequency oscillating electromagnetic field.
- Extension Cable (330130 series): Low-loss coaxial cable transmitting the raw oscillator signal from probe to driver. Length-matched to maintain system calibration.
- Driver / Oscillator-Demodulator (330180 series): Converts the raw probe signal into a conditioned 4–20 mA DC output proportional to gap distance. Provides power to the probe and performs temperature compensation.
Signal flow: Shaft displacement → Probe field perturbation → Extension cable → Driver demodulation → 4–20 mA output → DCS / Bently Nevada 3500 rack / Safety system

Technical FAQ
Q: Is this a complete system or just the probe?
A: This listing covers the complete matched system: probe, extension cable, and driver/oscillator-demodulator, as indicated by the full part number 330104-02-25-10-02-00.
Q: What target material is the factory calibration based on?
A: Standard calibration is performed on AISI 4140 steel. For non-standard target materials (e.g., stainless steel, titanium), a material correction factor must be applied per Bently Nevada application guidelines.
Q: Can this system interface directly with a Bently Nevada 3500 monitoring rack?
A: Yes. The 4–20 mA output is fully compatible with the 3500 series I/O modules. Verify the specific 3500 module input card specification for loop power requirements.
Q: What is the maximum cable run from driver to DCS?
A: The 4–20 mA current loop supports cable runs exceeding 300 m in typical industrial installations, subject to total loop resistance limits.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration data and certificates of conformance are available upon request for each serialized unit.
