Bently Nevada 330104-00-03-10-02-00 3300 XL 8 mm Metric Proximity Probe

Product Overview

The 330104-00-03-10-02-00 acts as a high-precision displacement transducer within the Bently Nevada 3300 XL 8 mm Proximity Transducer System. This metric-threaded probe utilizes eddy current technology to measure the gap between the probe tip and a rotating shaft. It provides critical data for axial position, radial vibration, and phase reference (Keyphasor) measurements in high-speed turbomachinery. We supply this unit as 100% Brand New original hardware, Made in the U.S.A., featuring integrated stainless steel armor for maximum durability in extreme industrial environments.

Part Number Breakdown

The 330104 series uses a modular coding system to define its mechanical and metric threading profile:

Technical Specifications

The 330104-00-03-10-02-00 delivers laboratory-grade accuracy in rugged field conditions:

• Probe Tip Diameter: 8 mm

• Thread Size: M10 x 1

• Linear Range: 2.0 mm (80 mils)

• Nominal Scale Factor: 7.87 V/mm (200 mV/mil)

• Case Material: AISI 303 or 304 Stainless Steel (SST)

• Tip Material: Polyphenylene sulfide (PPS)

• Operating Temperature: -51 °C to +177 °C (-60 °F to +351 °F)

• Armor Type: Flexible stainless steel armor (protects coaxial cable)

Engineering Advantages

• Enhanced Mechanical Armor: The integrated stainless steel armor shields the internal coaxial cable from abrasion, sharp bends, and physical impact. This prevents signal degradation or failure in environments where maintenance personnel or heavy tools may come into contact with sensor wiring.

• ClickLoc™ Interconnect System: The gold-plated ClickLoc™ connector features a specialized locking mechanism that prevents the cable from loosening due to machine vibration. This ensures a consistent, gas-tight electrical connection and eliminates signal "spikes" common with standard connectors.

• Metric Thread Integration: The M10 x 1 thread simplifies installation in machinery designed to metric standards, common in European and Asian equipment. The 30mm case length offers a compact footprint, ideal for mounting within specialized bearing housings or tight internal compartments.

• Exceptional Thermal Stability: The 3300 XL design maintains a constant scale factor regardless of temperature fluctuations within its operating range. This ensures that the vibration data remains accurate during the machine's thermal expansion phases during startup and full load.

• U.S.A. Manufacturing Standards: This probe meets the rigorous quality benchmarks of Bently Nevada. Upon request, we can provide an official Certificate of Origin (COO) to assist with international project compliance and import procedures.

FAQs

Q: Can I use this probe with a standard 3300 XL Proximitor® Sensor?

A: Yes. However, you must pair it with a 3300 XL Extension Cable. The total length of the probe plus the extension cable must match the calibrated length of the Proximitor (typically 5.0 or 9.0 metres total).

Q: What is the benefit of the "00" unthreaded length?

A: The "00" option means the probe body is fully threaded. This allows for maximum flexibility when setting the initial gap, as you can adjust the probe's depth through the entire 30mm case length.

Q: Does the stainless steel armor affect the eddy current signal?

A: No. The armor is a protective sleeve for the coaxial cable only. The sensing occurs at the PPS tip, which remains exposed. The armor simply ensures the electrical signal reaches the monitoring rack without interference from mechanical damage.

Q: Is the probe tip resistant to corrosive turbine oils?

A: Yes. The Polyphenylene sulfide (PPS) tip resists degradation from nearly all common industrial lubricants, hydraulic fluids, and chemical vapors found in turbomachinery environments.
