330103-00-11-50-02-00 | 3300 XL 8mm Proximity Probe | Bently Nevada

Product Overview

The Bently Nevada 330103-00-11-50-02-00 acts as the primary sensing element for the 3300 XL 8mm Proximitor® Sensor System. This eddy current proximity probe measures non-contacting shaft vibration and displacement (gap) in critical rotating machinery, such as high-speed compressors and turbines. By converting mechanical motion into a precise electrical signal, it facilitates continuous machinery protection. We supply this unit as 100% brand new and original, ensuring your monitoring infrastructure relies on genuine, factory-calibrated hardware.

Part Number Breakdown

The configuration for model 330103-00-11-50-02-00 defines the specific mechanical and electrical properties of the probe:

Technical Specifications

This 3300 XL 8mm probe provides consistent accuracy across industrial variables:

• Probe Tip Material: Polyphenylene sulfide (PPS)

• Thread Size: 3/8-24 UNF-2A

• Linear Range: 2.0 mm (80 mils)

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

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

• Probe Pressure Rating: 700 psi (48 bar)

• Connector Style: Gold-plated ClickLoc™ coaxial connection

• Target Material: AISI 4140 Steel (Standard calibration)

Engineering Advantages

• Extended Reach Integration: The 5.0-meter total length allows for direct connection to a Proximitor® sensor in a 5.0-meter system without an extension cable. This reduces the number of connection points, minimizing the risk of signal degradation or moisture ingress at intermediate junctions.

• Hermetic Pressure Integrity: The design features a hermetically sealed lead-to-case joint rated for 700 psi. This allows for direct installation through machine casings without risking fluid leaks or pressure loss, even in submerged oil applications.

• Corrosion-Resistant PPS Tip: The probe tip utilizes Polyphenylene sulfide (PPS), a high-performance thermoplastic. This material resists chemical attack from reactive industrial lubricants and moisture, preventing calibration shifts over years of service.

• Positive-Locking ClickLoc™ Connector: The gold-plated connector prevents signal noise and intermittent data loss caused by oxidation. The ClickLoc™ mechanism ensures the cable remains securely joined despite the high-frequency vibrations common in rotating machine housings.

• Environmental Connector Shielding: The standard protective boot (-02 option) shields the coaxial connection from environmental contaminants and moisture, preserving signal integrity from the probe to the monitoring system.

FAQs

• Do I need an extension cable for this 5.0-meter probe?

  If you are using a 5.0-meter Proximitor® system, this probe connects directly to the sensor without an extension cable. However, if you are using a 9.0-meter system, you must pair this probe with a 4.0-meter extension cable to reach the required electrical length.

• Is this Bently Nevada probe 100% brand new?

  Absolutely. We guarantee that every 330103-00-11-50-02-00 we ship is brand new and original in factory-sealed packaging. We do not provide refurbished or third-party compatible proximity hardware.

• What is the significance of the 1.1-inch case length?

  The 1.1-inch overall case length provides a stable mounting profile for medium-depth brackets, ensuring a secure fit in various bearing housing designs while maintaining the necessary thread engagement for vibration-proof mounting.

• Can this probe be used in hazardous areas?

  The -00 approval suffix indicates this model is for general-purpose industrial use. For applications in classified hazardous locations, you should select models with -05 (Multiple Approvals) or -CN (China Specific) certifications.
