- Temperature Stability – Thermally compensated Proximitor® electronics maintain ±1% accuracy across full operating range
- Plug-and-Play Compatibility – Direct replacement for existing 3300 XL installations; no recalibration required when replacing like-for-like
- Armored Cable Construction – Stainless steel braid protects against mechanical damage, EMI, and chemical exposure
- API 670 Compliant – Meets the 5th Edition standard for machinery protection systems
System Architecture & Signal Flow
The 330103-02-10-05-02-05 operates as a three-component eddy-current system:
- Probe (330103) – Generates a high-frequency electromagnetic field (1.0 MHz nominal) directed at the rotating shaft target.
- Extension Cable (330130-05-00) – Transmits the RF signal between probe and Proximitor® with controlled impedance (matched to system calibration).
- Proximitor® Sensor (330180-X1-05) – Demodulates the RF signal and outputs a DC-proportional voltage (–2 to –18 VDC) linearly representing gap distance. This output feeds directly into Bently Nevada 3500 or 3300 monitoring racks, DCS analog input cards, or standalone vibration monitors.
The complete system is factory-calibrated as a matched set on AISI 4140 steel targets. Field substitution of individual components will affect calibration and is not recommended without recalibration.

Technical FAQ
Q: Is this a complete system or individual components?
A: The 330103-02-10-05-02-05 is a complete, factory-matched proximity transducer system including probe, extension cable, and Proximitor® sensor. All three components are calibrated together and must be used as a set.
Q: Which Bently Nevada monitoring racks is this compatible with?
A: Compatible with Bently Nevada 3500 Series (3500/25, 3500/40M, 3500/42M, 3500/45, 3500/46), 3300 Series monitors, and any system accepting –24 VDC powered eddy-current transducers with standard coaxial output.
Q: What target material is required?
A: The system is calibrated for AISI 4140 steel. Other ferromagnetic alloys (e.g., 4340, 17-4 PH stainless) will require a target material correction factor per Bently Nevada TIL-021.
Q: Can I replace only the probe without replacing the full system?
A: Technically possible, but the system sensitivity will shift unless the replacement probe is from the same calibrated set. Full system replacement is recommended for API 670 compliance.
Q: Do you provide calibration certificates?
A: Factory calibration data is available for new OEM units. For surplus units, Konmask can arrange third-party calibration verification upon request.
