Bently Nevada 330101-00-76-20-02-05 – 8mm Eddy Current Proximity Transducer | 3300 XL Platform
Engineering Background: The Bently Nevada 3300 XL Series is the global industry benchmark for non-contacting eddy current measurement in rotating machinery protection. Engineered for continuous real-time shaft vibration and axial position monitoring, this platform is deployed in power generation, petrochemical, LNG, and heavy industrial facilities worldwide — where unplanned downtime carries catastrophic operational and financial consequences.
Product Positioning: The 330101-00-76-20-02-05 is an 8mm diameter proximity probe engineered for the 3300 XL Transducer System. It delivers high-resolution, non-contact displacement measurement with exceptional linearity and thermal stability — the preferred specification for procurement engineers designing API 670-compliant machinery protection systems. Konmask.com supplies verified, traceable units with full documentation support.

Engineering Advantages
- API 670 Compliant: Meets the 5th Edition standard for machinery protection systems — no re-qualification required for most plant installations.
- Eddy Current Technology: Immune to oil, steam, and process contamination; zero physical contact with the rotating shaft eliminates wear and maintenance intervals.
- High Thermal Stability: Calibrated scale factor maintained across the full –35°C to +177°C operating range without drift compensation.
- System Interoperability: Direct drop-in replacement within existing 3300 XL infrastructure — probe, extension cable, and Proximitor® Sensor remain fully compatible.
- Armored Cable Construction: Stainless steel armor protects signal integrity against mechanical damage in harsh plant environments.
- Long-Term Availability: Konmask.com maintains verified surplus and authorized distribution stock to support legacy plant installations.
System Architecture & Signal Flow
The 3300 XL Transducer System operates as a three-component signal chain:
- Proximity Probe (330101-00-76-20-02-05): Generates the eddy current field at the shaft surface and converts gap displacement to a raw electrical signal.
- Extension Cable (330130 Series): Transmits the signal from the probe tip to the Proximitor® Sensor, maintaining impedance integrity over distance.
- Proximitor® Sensor (3300 XL): Conditions and scales the signal to a –24 VDC output proportional to gap distance, feeding the monitoring system (e.g., 3500 rack or DCS).
This architecture ensures the scale factor (7.87 V/mm) is maintained system-wide, enabling direct integration with Bently Nevada 3500 Series monitors and third-party DCS/SIS platforms via standard 4–20 mA or voltage outputs.

Technical FAQ
Q: Is 330101-00-76-20-02-05 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. When paired with the correct 3300 XL Proximitor® Sensor and 330130 extension cable, the output signal is fully compatible with 3500 Series monitor input cards.
Q: Can this probe be used with non-Bently Nevada drivers?
A: The 3300 XL probe is calibrated specifically for the 3300 XL Proximitor® Sensor. Use with third-party drivers may alter the scale factor and is not recommended for API 670 applications without re-calibration.
Q: What do the part number suffixes encode (e.g., -02-05 vs -02-CN)?
A: Suffixes encode connector type, cable length, and regional certification variants. The -02-05 suffix denotes a standard 5m armored cable with international connector. Contact us to confirm the correct variant for your installation.
Q: Do you provide calibration certificates?
A: Calibration documentation from the original manufacturer is available for select stock. Please specify your requirement at the time of inquiry.
Q: What is the minimum order quantity?
A: We supply single units through to volume orders. Contact us for volume pricing and blanket order arrangements.
