- High Frequency Response – DC to 10 kHz bandwidth captures sub-synchronous, synchronous, and super-synchronous vibration components
- API 670 Compliant – Meets the mandatory protection standard for turbomachinery in oil & gas and power generation
- Integral Cable Design – Eliminates connector junction losses and reduces installation error risk
- 316 SS Housing – Corrosion-resistant construction for aggressive process environments including H₂S and chloride exposure
- Direct 3300 System Compatibility – Plug-and-play replacement for existing 3300 Series installations; no recalibration of proximitor required when replacing like-for-like
System Architecture & Signal Flow
The 330101-00-34-10-02-05 probe operates as the primary sensing element in a three-component eddy current measurement chain:
- Proximity Probe (330101-00-34-10-02-05) → Generates high-frequency electromagnetic field; detects target surface displacement via impedance change
- Extension Cable (330130 series) → Transmits the RF signal from probe tip to proximitor; length must be matched to system calibration
- Proximitor / Oscillator-Demodulator (330180 series) → Converts RF impedance signal to DC voltage output (−24 VDC bias, 200 mV/mil scale factor); interfaces with 3500 or 3300 rack monitors
Note: Total system cable length (probe integral cable + extension cable) must match the proximitor calibration. Consult Bently Nevada system documentation or contact Konmask technical support for length verification.

Technical FAQ
- Q: Is the 330101-00-34-10-02-05 compatible with the Bently Nevada 3500 monitoring rack?
- A: Yes. The 3300 Series probe system (probe + extension cable + 330180 proximitor) outputs a standard −24 VDC / 200 mV/mil signal fully compatible with 3500 Series monitor input cards.
- Q: Can this probe be used on non-ferrous target materials (e.g., titanium, Inconel)?
- A: The standard calibration is for AISI 4140 steel. Non-standard target materials require a custom calibration curve. Contact Konmask technical support for application-specific guidance.
- Q: What is the difference between the -02-05 and -02-00 suffix variants?
- A: The suffix encodes connector and cable jacket options. The -02-05 designates a specific termination and jacket configuration. Always order using the complete part number to ensure exact replacement.
- Q: Is ATEX / IECEx certification available for this probe?
- A: Bently Nevada offers ATEX-certified variants within the 3300 Series. Please confirm your hazardous area classification and contact us to verify the appropriate certified part number for your zone.
- Q: What is the typical lead time?
- A: In-stock units ship within 3–5 business days. For urgent MRO requirements, contact [email protected] for expedited options.
