Proven Application Environments
- Power Generation: Steam and gas turbine shaft vibration monitoring, rotor eccentricity measurement during startup/shutdown
- Oil & Gas: Compressor and pump train monitoring in upstream and downstream facilities; compatible with API 670 machinery protection systems
- Petrochemical: Continuous process machinery in hazardous-area installations
- Marine & Heavy Industry: Propulsion shaft monitoring, large motor bearing displacement
- Pulp & Paper / Steel Mills: High-temperature proximity sensing on process-critical rotating equipment
Engineering Advantages
- OEM 3300 XL Compatibility: Direct plug-and-play replacement within existing Bently Nevada 3300 monitor racks — no re-ranging or driver swap required
- Extended Temperature Probe: Rated to +177°C probe tip, suitable for high-temperature bearing housings without external cooling
- Matched System Calibration: Probe, extension cable, and driver are factory-calibrated as a matched set, ensuring ±1% linearity across the full measurement range
- EMI/RFI Shielding: Armored cable construction minimizes interference in electrically noisy industrial environments
- Long-Term Signal Stability: Eddy-current technology provides drift-free output over multi-year continuous operation cycles
System Architecture & Signal Flow
The 330910-00-14-05-02-00 system consists of three matched components operating as a calibrated unit:
- Probe (330910 series): Eddy-current sensing element mounted in the bearing housing, generating a high-frequency oscillating field directed at the rotating shaft surface.
- Extension Cable: Low-loss coaxial cable transmitting the demodulated signal from probe to driver/oscillator, maintaining impedance integrity over the rated cable length.
- Driver / Oscillator-Demodulator: Converts the probe’s impedance variation into a calibrated DC voltage output proportional to the gap distance. Output feeds directly into Bently Nevada 3300 monitor input cards.
Signal output polarity is negative: gap increases produce more negative voltage. This convention is consistent across all 3300 XL system components and must be observed when configuring monitor alarm setpoints.

Technical FAQ
Q: Is the 330910-00-14-05-02-00 compatible with the Bently Nevada 3500 monitoring system?
A: No. The 330910 series is calibrated for the 3300 XL monitor platform. For 3500 series monitors, the 330780 or 330930 probe systems are required. Cross-platform use without recalibration will produce measurement errors.
Q: Can the probe be used with non-steel target materials?
A: Yes, but a material-specific calibration curve must be applied. Standard calibration is for AISI 4140 steel. Contact our technical team for calibration data on Inconel, titanium, or other alloys.
Q: What is the maximum continuous operating temperature at the probe tip?
A: +177°C (351°F). Exceeding this rating will degrade the probe’s epoxy encapsulation and void calibration.
Q: Are matched system sets (probe + extension + driver) available?
A: Yes. We recommend ordering as a matched set to ensure factory calibration integrity. Individual components are also available for replacement of a single failed element.
Q: Do you provide installation and commissioning support?
A: Technical documentation is provided with every order. Remote commissioning support is available upon request for qualified engineering teams.
