Bently Nevada 330104-00-09-05-11-05 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-09-05-11-05 operates as a rugged industrial eddy current sensor within the definitive 3300 XL 8mm proximity transducer framework. This precision sensor measures static shaft position and dynamic displacement on critical rotating machinery, such as high-speed steam turbines, centrifugal compressors, and industrial pumps.

By generating a high-frequency electromagnetic field around its tip, the probe tracks micro-inch changes in gap distance without ever contacting the target surface. This non-contact measurement provides crucial real-time data to machinery protection systems to prevent catastrophic rotor-to-stator rubs. We supply this asset-protection hardware exclusively as a 100% brand new, original factory-sealed unit, guaranteeing a pristine PPS tip element, virgin coaxial cable shielding, and untouched factory calibration variables.

Part Number Breakdown

The Bently Nevada 3300 XL suffix options dictate the exact physical architecture of the probe assembly. The table below decodes the specific hardware layout for the 330104-00-09-05-11-05 configuration:

Technical Specifications

The list below tracks the primary electrical, mechanical, and material operational boundaries of the 3300 XL 8mm probe assembly:

• Probe Tip Material: Polyphenylene Sulfide (PPS) high-performance glass-filled plastic

• Probe Case Material: AISI 303 stainless steel threaded barrel assembly

• Nominal Linear Range: 2.0 mm (80 mils) total linear displacement window

• Scale Factor Sensitivity: 7.87 V/mm (200 mV/mil) when combined with 3300 XL Proximitor

• Operating Temperature Limits: -51 °C to +177 °C (-60 °F to +350 °F) probe tip zone

• System Connection: Coaxial ClickLoc gold-plated pin mating junction

• Armored Protection: Integrated stainless steel flexible conduit over the raw cable

Engineering Advantages

• Defeats Fluid Degradation via Armored Shielding: This model incorporates option code 11, covering the raw coaxial insulation with a rugged, flexible stainless steel armor jacket. This metal barrier stops splashing synthetic lubrication oils, hot hydraulic fluids, and caustic cleaning solvents from slicing or melting the internal signal conductor, which prevents system grounding errors.

• Eliminates Signal Dropout via Lockable ClickLoc Connectors: The gold-plated coaxial termination utilizes an internal locking ring system. This connector design withstands the continuous high-frequency vibrations of compressor casings, preventing the mechanical plug from backing out or rattling loose, which eliminates false trip alarms in safety shutdown circuits.

• Survives High-Thermal Thermal Stress at the Bearing Housing: The glass-filled PPS plastic tip resists extreme thermal fluctuations and physical chemical degradation. This material choice allows engineers to thread the probe directly into hot bearing housings where temperatures frequently exceed 100 degrees Celsius, ensuring long-term structural integrity without tip deformation.

FAQs

• Can this 0.5-meter probe connect directly to a 3300 XL Proximitor sensor without an intermediate extension cable?

  No. Standard Bently Nevada 3300 XL systems require a precise total electrical length of either 5.0 meters or 9.0 meters to maintain the 200 mV/mil calibration curve. Because this specific probe features an integrated length of 0.5 meters (Option 05), technicians must add a matching 4.5-meter or 8.5-meter extension cable to complete the loop before landing the coaxial run at the Proximitor panel.

• What critical safety rules protect the probe tip from crushing destruction during mechanical installation?

  Technicians must monitor the gap voltage with a digital multimeter while threading the probe into the mounting bracket. Never twist the probe blindly against a stationary target face. Thread the probe until the multimeter reads the appropriate target voltage (typically around -10V DC for the center of the linear range), then secure the locknut to prevent the probe from migrating toward the spinning shaft during operation.

• Does this probe require isolation from surrounding metal structures during mounting?

  The eddy current field radiates outwards from the 8mm probe tip in a conical shape. If you mount the probe tip too close to the sidewalls of a narrow viewing hole, the surrounding metal will distort the electromagnetic lines, throwing off the voltage readings. Maintain a clear radius of at least 3 times the probe tip diameter (24 mm) around the sensing face to prevent side-metal interference.
