330101-00-20-90-02-CN | Bently Nevada 3300 XL 8mm Probe 9m

Product Overview

The 330101-00-20-90-02-CN is an 8 mm industrial proximity probe from Bently Nevada's 3300 XL Proximity Transducer System series. Engineered for non-contact eddy current vibration and displacement monitoring on critical rotating machinery, this probe features patented TipLoc and CableLoc technologies providing up to 330 N (75 lbf) cable pull strength. Configured with a 3/8-24 UNF thread, 0.0 in unthreaded length, 2.0 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 China country-specific approvals (CN option), it delivers direct long-cable signal connectivity with high linear accuracy.

Core Technical Advantages

• Patented CableLoc & TipLoc Engineering: Advanced molding processes create an unbreakable bond between the PPS probe tip and stainless steel casing while providing 330 N (75 lbf) cable pull resistance.
• Integrated 9.0-Meter Cable Length: Connects directly to a 9-meter 3300 XL Proximitor Sensor without needing secondary extension cable connections.
• High-Temperature & Humidity Resilience: Operates continuously from -52 °C to +177 °C (-62 °F to +350 °F) with a Viton O-ring seal maintaining under 3% ASF variation at 93% relative humidity (IEC 68-2-3 test).
• China Country-Specific Certification (CN): Fully certified under regional Chinese industrial standards for seamless deployment in China-based processing facilities.

Technical Specifications

Industrial Solutions

• Steam & Gas Turbines: Measures shaft vibration and axial position for continuous machine protection loops.
• Centrifugal Gas Compressors: Tracks dynamic rotor stability and oil film clearance under high-pressure process loads.
• China Regional Process Plants: Fully compliant with CN country-specific approvals for simplified regulatory approval in Chinese facilities.
• Long-Distance Bearing Housing Routing: Integrated 9.0 m cable allows direct wiring to Proximitor sensors without extra inline junction points.

Wiring & Installation

Gap Adjustment & Midpoint Calibration

Thread the 2.0 in probe case into the port and adjust mechanical clearance to approximately 1.27 mm (50 mils) to set the optimal -9 Vdc operating midpoint voltage.

Cable Support & Weight Density Routing

Route the 9.0 m cable (323 g/m linear weight rating) through protective conduit, taking care to maintain proper bend radii along the 29.5 ft length.

Field Wiring Interconnection

Use 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 rack monitor.

ClickLoc Connector Termination

Connect the Miniature coaxial ClickLoc connector straight into the 9 m 3300 XL Proximitor Sensor, hand-tightening until tactile latching is confirmed.

Engineering Advantages

• Thicker PPS Tip Encapsulation: Molded polyphenylene sulfide (PPS) tip provides robust coil protection against chemical exposure and physical impact.
• Calibrated 9-Meter Linearity: Maintains strict DSL deviation under ±0.038 mm (±1.5 mil) across the full 9m measurement range.
• Differential Pressure Sealing: Integrated Viton O-ring reliably seals differential pressure between the probe tip and case.

Technical FAQs
