Bently Nevada 330101-00-58-10-02-00 Probe 3300 XL 8mm

Product Overview

The 330101-00-58-10-02-00 is an industry-standard 3300 XL 8mm Proximity Transducer Probe engineered by Bently Nevada for high-precision non-contact vibration and displacement measurements on critical rotating machinery. Featuring a 3/8-24 UNF threaded body with an extended 5.8-inch overall case length and unarmored cable construction, this probe converts eddy-current distance metrics into precise voltage signals for machinery protection systems. Utilizing patented TipLoc and CableLoc physical bonding technologies, the 330101-00-58-10-02-00 delivers exceptional mechanical strength with a cable pull resilience of 330 N (75 lbf). Built with a thick polyphenylene sulfide (PPS) plastic tip enclosed in an AISI 303/304 stainless steel casing, this probe offers superior physical robustness against industrial wear and vibration.

Core Technical Advantages

• Patented Structural Bonding: Utilizes Bently Nevada's patented TipLoc molding method for a stronger bond between probe tip and body, along with CableLoc design providing 330 N (75 lbf) cable pull strength.
• Extended 5.8-Inch Case Reach: Features a 5.8-inch overall stainless steel thread length (-58 option) to access deep bearing housings and recessed mounting locations without additional sleeve adapters.
• Linear Measurement Precision: Delivers a consistent linear displacement window of 0.25 to 2.3 mm (10 to 90 mils) with a standard Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) ±5%.

Technical Specifications

Industrial Applications

• Steam & Gas Turbine Radial Vibration: Measures journal bearing shaft displacement and dynamic vibration profiles inside heavy power generation machinery.
• Centrifugal Compressor Axial Position: Monitors thrust collar movement to protect high-pressure gas processing compressors from destructive internal contact.
• Deep-Housing Gearbox Monitoring: Reaches internal gear shaft surfaces through thick external casings utilizing the 5.8-inch long probe body.
• Hydroelectric Turbine Runout: Operates in high-moisture turbine environments to track rotational stability and shaft runout.

Wiring & Installation

• Proximitor System Loop: Connect the 1.0-meter probe cable to a 4.0-meter 3300 XL extension cable and Proximitor Sensor to maintain a calibrated 5.0-meter system length.
• Mechanical Case Mounting: Thread the 3/8-24 UNF body into the tapped mounting hole. Ensure proper clearance to prevent damaging the polyphenylene sulfide (PPS) tip during insertion.
• Gap Setting Calibration: Adjust the probe gap position until the Proximitor Sensor reads -9 Vdc (approximately 1.27 mm or 50 mils gap distance) for optimal radial vibration tracking.
• Field Wiring Guidelines: Use 3-conductor shielded triad cable (0.2 to 1.5 mm²) for field wiring up to 305 meters (1,000 feet) between the Proximitor Sensor and monitor rack.

Engineering Advantages

• ClickLoc Locking Connectors: Gold-plated coaxial ClickLoc connectors prevent inter-cable loosening caused by continuous high-amplitude machinery vibration.
• Viton® O-Ring Differential Seal: Integrated Viton® O-ring seals differential pressure between probe tip and case for process containment integrity.
• Environmental Resilience: Demonstrates high stability with less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for 56 days.

Technical FAQs

Q1: What does -58 mean?
A1: Indicates a 5.8-inch overall stainless steel case length for deeper mounting reach.

Q2: Why set gap to -9 Vdc?
A2: Ensures the probe centers in its 0.25–2.3 mm linear range.

Q3: Is the cable oil resistant?
A3: Yes. Use FluidLoc models to prevent internal oil migration.
