330880-28-40-058-01-02 Shaft Vibration Sensor Assembly

Product Overview

The Bently Nevada 330880-28-40-058-01-02 represents the pinnacle of integrated sensing technology with the PROXPAC XL series. This self-contained assembly combines an 8mm proximity probe and a Proximitor® sensor into a single, ruggedized housing. It eliminates the need for separate extension cables and external Proximitor® housings, significantly reducing installation complexity and potential failure points. This assembly provides high-precision shaft vibration and radial position measurements for critical turbomachinery, including high-speed compressors and pumps. We supply this unit as 100% Brand New and Original in Factory Packing, ensuring peak performance for your predictive maintenance program.

Technical Specifications

The PROXPAC XL utilizes Polyphenylene Sulfide (PPS) to withstand the chemically aggressive environments typical of industrial rotating machinery.

Engineering Advantages

• Elimination of Extension Cables: The PROXPAC XL design integrates the signal conditioner directly onto the probe assembly. This removes the electrical "mismatch" risks associated with traditional extension cables and improves overall signal-to-noise ratios.

• Streamlined Field Installation: Because the unit requires no separate housing for a Proximitor®, you can mount the assembly directly to the machine casing. This reduces the number of parts to manage and speeds up commissioning in tight plant spaces.

• Extreme Chemical Resistance: The molded PPS thermoplastic housing resists degradation from synthetic oils, fuels, and common industrial solvents. This ensures the internal electronics remain hermetically sealed against the harsh atmosphere found in compressor decks.

• Enhanced Predictive Maintenance: By delivering high-resolution shaft position and vibration data, the 330880-28-40-058-01-02 identifies early-stage bearing wear and shaft misalignment, allowing for scheduled interventions rather than emergency shutdowns.

• Direct 3500 System Interface: The sensor wires directly to Bently Nevada 3500 series monitors (such as the 3500/40 or 3500/42M), maintaining full compatibility with your existing machinery protection architecture.

FAQs

• How does the PROXPAC XL differ from a standard 3300 XL probe?

  A standard 3300 XL probe requires a separate extension cable and a remote Proximitor® sensor. The PROXPAC XL (330880) integrates all these components into one single assembly for easier installation and improved reliability.

• Is the 5.8-meter cable length fixed?

  Yes, the "-058" in this specific part number designates a 5.8-meter cable. If your application requires a different length, you must select the corresponding part number to ensure electrical calibration remains accurate.

• What mounting considerations should I follow?

  Ensure the mounting surface is clean and matches the thread option (-01) of the assembly. Proper gap calibration between the probe tip and the shaft is essential for linear signal output.

• Does this assembly support touch-screen monitoring?

  While the sensor itself provides raw data, it integrates perfectly with the Bently Nevada 3500/94 VGA Display Router, allowing you to view its vibration data on touch-screen interfaces.
