Bently Nevada 330104-00-05-05-02-05 3300 XL 8 mm Metric Proximity Probe

Product Overview

The 330104-00-05-05-02-05 represents the high-precision standard for non-contact displacement measurement within the Bently Nevada 3300 XL ecosystem. This metric-threaded 8 mm probe utilizes eddy current technology to monitor vibration and axial position in critical rotating machinery. Designed for seamless integration into M10 x 1 ports, it delivers essential data to machinery protection systems (MPS). We supply this unit as 100% Brand New original hardware, Made in the U.S.A., featuring a 0.5-meter cable and comprehensive global hazardous area certifications.

Part Number Breakdown

The 330104 series utilizes a modular nomenclature to define precise mechanical and electrical specifications:

Technical Specifications

The 330104-00-05-05-02-05 ensures laboratory-grade accuracy in rugged plant environments:

• 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)

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

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

• Tip Material: Polyphenylene sulfide (PPS)

• Connector Type: Gold-plated ClickLoc™ miniature coaxial connector

Engineering Advantages

• Global Explosion-Proof Compliance: The "-05" approval option carries CSA, ATEX, and IECEx certifications. This multi-certification ensures compliance with international safety standards, making it the preferred choice for oil and gas or chemical processing facilities worldwide.

• ClickLoc™ Interconnect Security: The gold-plated ClickLoc™ connector system features a self-locking mechanism. This prevents the cable from backing out due to machine vibration, ensuring a low-resistance electrical path and eliminating the signal "spikes" common with standard connectors.

• Chemical and Thermal Resilience: The Polyphenylene sulfide (PPS) tip resists degradation from hot turbine oils and industrial lubricants. The probe maintains a stable scale factor throughout its thermal range, ensuring accurate vibration data during machine startup and full-load operation.

• High-Density Metric Mounting: The M10 x 1 thread allows for direct installation into metric machinery without the need for conversion adapters. The 50 mm case length provides ample adjustability for setting the probe gap in various bearing housing thicknesses.

• Non-Contact Sensing Technology: The probe measures shaft movement without physical contact. This removes mechanical wear and allows for the continuous monitoring of high-speed shafts (over 30,000 RPM) for decades of reliable operation.

FAQs

Q: Why does this probe have a 0.5-meter total length?

A: The 0.5-meter length provides a short, manageable lead that typically connects to an extension cable just outside the machine casing. You must pair this probe with a 3300 XL Extension Cable to meet the total system length (usually 5.0 or 9.0 meters) required by the Proximitor® Sensor.

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

A: The "00" option indicates that the probe body is threaded along its entire 50 mm case. This allows you to screw the probe deep into a mounting bracket or port, providing maximum gapping flexibility for different machine geometries.

Q: Can I use this probe with a non-XL Bently Nevada system?

A: While the 3300 XL probe is physically compatible with older 3300 systems, we recommend against mixing components. To achieve the specified 200 mV/mil accuracy and thermal stability, you should use a 3300 XL probe, extension cable, and Proximitor sensor together.

Q: How do I verify the probe gap during installation?

A: Connect the probe to its Proximitor sensor and monitor the DC output voltage. Adjust the probe position until the voltage reads approximately -10.0 VDC (the center of the linear range) before tightening the mounting nuts.
