Bently Nevada 3300 XL 8mm Proximity Probe 330101-00-08-10-02-00

Product Overview

The 330101-00-08-10-02-00 is an industry-standard 3300 XL 8mm Proximity Transducer Probe engineered by Bently Nevada for high-precision non-contact vibration and position measurements on critical rotating machinery. Featuring a standard 3/8-24 UNF threaded body and unarmored cable construction, this probe converts eddy-current displacement metrics into high-accuracy voltage signals for machinery protection systems. Utilizing patented TipLoc and CableLoc physical bonding technologies, the 330101-00-08-10-02-00 delivers exceptional mechanical strength with a cable pull resilience of 330 N (75 lbf). Built with a rugged polyphenylene sulfide (PPS) plastic tip enclosed in an AISI 303/304 stainless steel casing, this probe delivers long-term durability in extreme turbomachinery environments.

Core Technical Advantages

• Patented Structural Integrity: Features Bently Nevada's patented TipLoc molding method to secure the probe tip to the stainless case, along with CableLoc design providing up to 330 N (75 lbf) pull strength.
• Linear Measurement Range: Delivers a consistent linear displacement window of 0.25 to 2.3 mm (10 to 90 mils) with an accurate scale factor of 7.87 V/mm (200 mV/mil).
• Extreme Thermal Performance: Engineered to withstand harsh internal casing temperatures ranging from -52°C to +177°C (-62°F to +350°F), with special extended-range options handling tip temperatures up to +218°C (+425°F).

Technical Specifications

Industrial Applications

• Steam & Gas Turbine Radial Vibration: Measures journal bearing shaft displacement and dynamic vibration profiles inside power generation turbines.
• Centrifugal Compressor Axial Position: Monitors thrust collar movement to protect high-pressure gas compressors from destructive axial contact.
• Heavy Industrial Gearbox Monitoring: Tracks gear shaft eccentricity and alignment conditions in petrochemical processing drives.
• Hydroelectric Generator Shaft Alignment: Operates in high-moisture turbine housings to track rotational stability and runout.

Wiring & Installation

• Proximitor System Compatibility: Connect the 1.0-meter probe cable to a matching 3300 XL extension cable and Proximitor Sensor to maintain the total calibrated system length (5.0 or 9.0 meters).
• Mechanical Thread Installation: Screw the 3/8-24 UNF threaded probe body into the mounting bracket or bearing housing. Torque properly to avoid over-stressing the stainless case threads.
• Gap Calibration Setup: Adjust the probe gap until the Proximitor Sensor outputs an optimal radial gap voltage of -9 Vdc (approximately 1.27 mm or 50 mils gap distance).
• Connector Protection: Use Bently Nevada connector protectors or weather-sealed junction boxes to isolate the coaxial ClickLoc connector from oil, water, and conductive debris.

Engineering Advantages

• ClickLoc Coaxial Connectors: Features gold-plated mechanical locking connectors that prevent inter-cable loosening under heavy machinery vibration.
• High Environmental Resistance: Demonstrates high stability in humid conditions with less than 3% ASF change under 93% relative humidity (56-day test protocol).
• Long Distance Signal Routing: Supports field cabling runs up to 305 meters (1,000 ft) between the Proximitor Sensor and monitoring rack when using shielded triad cable.

Technical FAQs

Q1: What does -10 mean?
A1: Indicates a 1.0 m cable, forming a 5.0 m loop with a 4.0 m cable.

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.
