330103-00-05-10-02-00 | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330103-00-05-10-02-00 serves as a core sensing element within the 3300 XL Proximity Transducer System. This eddy current probe provides high-precision, non-contact displacement data for critical rotating assets such as turbines, compressors, and motors. We guarantee this unit as 100% Brand New and Original, manufactured in the USA to meet rigorous OEM vibration monitoring standards.

Part Number Breakdown

The 330103 series utilizes a specific configuration code to define its mechanical and electrical footprint:

Technical Specifications

This probe delivers a linear voltage output proportional to the gap between the probe tip and the target shaft.

• Sensing Range: 2.0 mm (80 mils) linear range

• Operating Temperature: –35°C to +177°C (–31°F to +350°F)

• Insulation Resistance: > 10 MΩ @ 500 VDC

• Probe Tip Diameter: 8 mm (Standard 3300 XL style)

• Construction: Rugged Stainless Steel (AISI 303/304)

• Mounting: M10 x 1.0 Mounting Thread with included locknut

• Weight: 0.3 kg

Engineering Advantages

• High-Temperature Resilience: The FEP-insulated cable and stainless steel body allow the sensor to operate continuously in zones reaching +177°C. This ensures data stability in hot-running turbine bearing housings.

• Secure Click-On Connectivity: The ClickLoc™ miniature coaxial connector employs a mechanical locking detent. This feature eliminates signal drift or "NOT OK" status errors caused by connectors vibrating loose over time.

• Deep-Reach Mounting: The 5.0-inch case length facilitates installation through thick machine casings. This allows the probe to reach the target shaft surface without requiring complex custom mounting adapters.

• Immunity to Interference: The 75 $\Omega$ triaxial cable design effectively shields the signal from electromagnetic interference (EMI) commonly found near high-voltage motor leads and variable frequency drives (VFDs).

FAQs

Is this 1.0m probe compatible with a 5-meter or 9-meter system?

To maintain a 200 mV/mil scale factor, the total electrical length (probe + extension cable) must match the Proximitor® calibration. This 1.0m probe pairs with a 4.0m extension cable for a 5-meter system or an 8.0m extension cable for a 9-meter system.

What precautions should I take during the mechanical installation?

Always use a digital voltmeter (DVM) to monitor the DC gap voltage while threading the probe into the bracket. This prevents the probe tip from accidentally striking the shaft, which can damage the PPS tip material.

Does this probe require individual calibration?

No. As part of the 3300 XL series, this probe is fully interchangeable. You can replace it with any other 330103 probe of the same electrical length without re-calibrating the Proximitor® sensor.

What is the benefit of the "Brand New" status for this specific model?

Mechanical vibration sensors suffer from internal fatigue and tip degradation over time. A 100% Brand New unit guarantees the integrity of the internal coil and the factory-sealed connector, preventing false vibration trips caused by aged hardware.
