330101-00-28-90-02-05 Bently Nevada 8mm Vibration Probe 9m

Product Overview

The 330101-00-28-90-02-05 is an 8 mm industrial proximity probe from Bently Nevada's 3300 XL Proximity Transducer System series. Designed for eddy current non-contact vibration and shaft position monitoring on critical rotating machinery, this sensor features patented TipLoc and CableLoc technologies providing up to 330 N (75 lbf) cable pull resistance. Configured with a 3/8-24 UNF thread, 0.0 in unthreaded length, 2.8 in case length, an integrated 9.0 m (29.5 ft) cable with a linear weight density of 323 g/m (11.4 oz), Miniature coaxial ClickLoc connector, and multi-agency approvals (CSA, ATEX, IECEx), it offers direct long-cable connectivity with high precision.

Core Technical Advantages

• Patented CableLoc & TipLoc Design: Advanced molding processes create a robust bond between the PPS probe tip and stainless steel housing while resisting 330 N (75 lbf) cable pull forces.
• Integrated 9.0-Meter Cable Length: Allows long-distance connections directly to a 9-meter 3300 XL Proximitor Sensor without requiring external extension cables.
• High-Temperature & Humidity Resistance: Standard operating range from -52 °C to +177 °C (-62 °F to +350 °F) with a Viton O-ring seal maintaining less than 3% ASF change under 93% relative humidity (IEC 68-2-3 test).
• Hazardous Location Certified: Approved under CSA, ATEX, and IECEx hazardous area safety standards for global industrial process plants.

Technical Specifications

Industrial Solutions

• Turbine Thrust & Radial Position: Measures dynamic shaft vibration and axial displacement in steam and gas turbines.
• Centrifugal Gas Compressors: Monitors oil film stability and high-speed shaft clearance under variable process loads.
• Hazardous Location Refineries: Certified by CSA, ATEX, and IECEx for safe deployment in explosive gas atmospheres.
• Remote Junction Box Installations: The integrated 9-meter cable bridges long distances from bearing housings directly to control panels.

Wiring & Installation

Gap Adjustment & Voltage Calibration

Thread the 2.8 in case into the mounting bracket and adjust mechanical clearance to approximately 1.27 mm (50 mils) to achieve an optimal -9 Vdc operating midpoint voltage.

Cable Support & Weight Density Routing

Route the 9.0 m cable (323 g/m weight rating) inside protective conduit or tray systems, ensuring minimum bend radii are maintained along the 29.5 ft length.

Field Wiring Interface

Use recommended 3-conductor shielded triad field wire (0.2 to 1.5 mm² / 16 to 24 AWG) for runs up to 305 meters (1,000 feet) between the Proximitor Sensor and monitor.

ClickLoc Coaxial Engagement

Connect the Miniature coaxial ClickLoc connector directly to the 9 m 3300 XL Proximitor Sensor, hand-tightening until tactile latching is verified.

Engineering Advantages

• Thicker PPS Tip Encapsulation: Molded polyphenylene sulfide (PPS) tip provides superior coil protection against physical abuse and harsh oil environments.
• Calibrated 9-Meter Linearity: Engineered to maintain a tight deviation from best fit straight line (DSL) under ±0.038 mm (±1.5 mil) across the 9m scale.
• High Pressure Sealing: Integrated Viton O-ring seals differential pressure between the probe tip and case.

Technical FAQs

Q1: What does model code 330101-00-28-90-02-05 specify?
