Proven Application Environments
- Power Generation: Steam turbines, gas turbines, and hydro generators requiring continuous shaft vibration monitoring per API 670.
- Oil & Gas / Petrochemical: Centrifugal compressors, expanders, and pipeline pumps in hazardous-area installations.
- Pulp & Paper / Steel Mills: High-speed rotating equipment with demanding thermal and contamination environments.
- Marine Propulsion: Shaft monitoring on vessels requiring compact, corrosion-resistant sensor assemblies.
- OEM Machine Builders: Integration into new machinery protection panels alongside Bently Nevada 3500 or 3300 rack systems.
Engineering Advantages
- Non-Contact Measurement: Eddy-current technology eliminates mechanical wear, ensuring sensor longevity exceeding 10 years in continuous service.
- Wide Frequency Bandwidth: DC to 10 kHz response captures both slow-roll runout and high-frequency sub-synchronous instabilities.
- API 670 Compliance: Drop-in replacement for existing 3300 XL installations without recalibration of the monitor rack.
- Thermal Stability: Probe rated to +177°C for direct installation adjacent to bearing housings without thermal derating.
- Plug-and-Play Integration: Fully compatible with Bently Nevada System 1 software for real-time trending, alarm management, and predictive analytics.
- Hazardous Area Options: ATEX / IECEx certified variants available for Zone 1 / Zone 2 classified installations.
System Architecture & Signal Flow
The 330104-00-21-10-02-00 operates as a three-component eddy-current system:
- Probe (330104 series): 8 mm tip generates a high-frequency electromagnetic field. Gap changes between probe tip and rotating shaft modulate the field impedance.
- Extension Cable: Low-loss coaxial cable transmits the modulated signal from the probe to the driver/oscillator with minimal signal degradation.
- Driver / Oscillator (330180 series): Demodulates the carrier signal and outputs a DC-coupled voltage proportional to gap distance, scaled at 7.87 V/mm, directly readable by the 3300 XL monitor input card.
The monitor card performs signal conditioning, alarm comparison, and relay actuation. Integration with System 1 software enables historian trending, spectrum analysis, and orbit plot generation.

Technical FAQ
Q: Is the 330104-00-21-10-02-00 compatible with the Bently Nevada 3500 monitoring system?
A: The 3300 XL transducer system is optimized for 3300 XL monitors. For 3500 system compatibility, please consult the 330730 or 330900 series probes. Contact us to confirm compatibility with your specific rack configuration.
Q: Can this probe measure non-ferrous shaft materials?
A: Yes, but a material-specific calibration is required. The standard scale factor (7.87 V/mm) is calibrated for AISI 4140 steel. Konmask can supply application-specific calibration data upon request.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing is available for orders of 5 units or more.
Q: Do you provide installation and commissioning support?
A: Yes. Remote technical support is included. On-site commissioning assistance can be arranged for large-scale projects.
Q: How long is the lead time for in-stock units?
A: In-stock units ship within 3–5 business days. For out-of-stock items, lead time is typically 4–8 weeks depending on OEM availability.
