Engineering Background
The Bently Nevada 3300 XL Proximity Transducer System is the global benchmark for continuous, non-contact shaft vibration and position measurement in rotating machinery. Developed and refined over decades of field deployment, the 3300 XL series is the preferred solution for turbines, compressors, pumps, and motors in oil & gas, power generation, and heavy process industries.
Product Positioning
The 330101-00-16-10-02-05 is a 5 mm eddy current proximity probe with a 16-inch (406 mm) integral armored cable, designed for direct integration into Bently Nevada 3300 XL monitoring systems. It delivers high-resolution, real-time radial vibration and axial position data critical for machinery protection and condition monitoring programs.

- Proven field reliability: Deployed globally in refineries, LNG plants, and power stations
System Architecture & Signal Flow
The 330101-00-16-10-02-05 probe operates as part of a three-component transducer system:
- Proximity Probe (330101-00-16-10-02-05): Generates an eddy current field at the probe tip; gap changes modulate the oscillator circuit.
- Extension Cable (330130 series): Transmits the modulated signal from the probe to the Proximitor® driver. Total cable length (probe + extension) must equal the system-calibrated length (typically 5 m or 9 m).
- Proximitor® Driver (330180 series): Demodulates the signal and outputs a DC voltage proportional to the probe-to-target gap (–2 to –18 VDC). This output feeds directly into Bently Nevada 3500 or 3300 monitoring racks.
Note: All three components must be from the same calibrated system family to maintain specified accuracy.

Technical FAQ
Q: Can this probe be used with a non-Bently Nevada monitoring system?
A: Yes, provided the receiving system accepts a –2 to –18 VDC analog output and the Proximitor® driver is powered correctly. However, system accuracy is only guaranteed when used with matched Bently Nevada components.
Q: What is the difference between the 330101 and 330105 probe series?
A: The 330101 series uses a 5 mm tip diameter; the 330105 series uses an 8 mm tip, offering a wider linear range (0.5–4.0 mm) and is preferred for larger shaft diameters.
Q: Is recalibration required after replacement?
A: If replacing with an identical part number from the same calibrated system family, recalibration is typically not required. Always verify with your site’s instrumentation engineer and applicable API 670 procedures.
Q: What is the maximum operating temperature?
A: The probe body is rated to +177°C. The integral cable insulation limits continuous exposure; consult the Bently Nevada datasheet (D350672) for derating curves at elevated temperatures.
Q: Do you provide ATEX-certified units?
A: Yes. The 330101 series is available with ATEX/IECEx certification for Zone 1/Zone 2 hazardous area installations. Confirm the suffix codes on your order for the correct certification variant.
