Bently Nevada 330101-00-65-50-02-CN 8mm Eddy Current Probe

Product Overview

The Bently Nevada 330101-00-65-50-02-CN is a high-performance 3300 XL 8 mm Proximity Probe engineered for non-contact vibration and shaft position monitoring on critical machinery. Manufactured in the USA, this eddy current sensor features a 3/8-24 UNF thread, a 6.5-inch overall case length, and an integrated 5.0-meter standard cable with a total cable weight density of 323 g/m (11.4 oz/m). Built with patented TipLoc and CableLoc technologies, it delivers superior mechanical strength and accurate linear signal output across demanding industrial applications.

Key Technical Features

• Robust Mechanical Design: Features TipLoc molding for tip bonding and CableLoc technology providing 330 N (75 lbf) cable pull strength.
• High-Accuracy Linear Range: Provides an 80 mil (2 mm) linear range with a standard 200 mV/mil (7.87 V/mm) Incremental Scale Factor.
• Rugged Enclosure & Tip: Molded PPS plastic probe tip paired with AISI 303/304 stainless steel casing ensures maximum physical protection.
• Secure Interconnects: Equipped with a miniature coaxial ClickLoc connector to prevent accidental cable disconnections.

Technical Specifications

Installation & Field Guide

• Gap Setting: Set the probe initial mechanical gap to -9 Vdc (approximately 1.27 mm or 50 mils) to position it in the center of the 80 mil linear range.
• Field Wiring: Use 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable up to a maximum length of 305 meters (1,000 feet) to the Proximitor Sensor.
• Low Temperature Limits: Avoid exposing the probe to temperatures below -34°C (-30°F) during operation to prevent premature failure of the internal Viton O-ring seal.

Engineering Advantages

• High Environmental Resistance: Demonstrates less than 3% change in Average Scale Factor when tested at 93% relative humidity per IEC 68-2-3.
• Interchangeability: Meets strict deviation from best fit straight line (DSL < ±0.025 mm) standards, allowing seamless drop-in replacements without recalibration.
• Differential Pressure Sealing: Built-in Viton O-ring seals differential pressure between the probe tip and case, protecting field hardware.

Technical FAQs

Q1: What does the "CN" suffix stand for in the part number?
A1: The "CN" option indicates country-specific approval, certifying the probe for regulatory compliance and installation in specific regional markets.

Q2: Can I order an official Certificate of Origin (COO) for this product?
A2: Yes, a formal Certificate of Origin verifying USA manufacturing can be provided upon request at the time of purchase.

Q3: Does the 5.0-meter probe require a matching extension cable?
A3: This 330101 model includes a total length of 5.0 meters directly. Verify your total system length matches the 3300 XL Proximitor Sensor rating (5m or 9m system) for accurate calibration.
