Bently Nevada 3300 XL 8mm Probe: Your Precision Machinery Sentinel

Meet the Bently Nevada 330101-48-71-20-02-CN, a superior 8mm proximity probe engineered for unwavering reliability in industrial monitoring. This sensor delivers precise vibration and position measurement to safeguard critical assets like turbines, pumps, and compressors. Its extended 2-meter cable and robust 8mm stainless steel body are built for durability in demanding environments. While it features the standard cable, its patented TipLoc and CableLoc designs ensure a secure, long-lasting installation. This model is your trusted choice for maintaining operational excellence and preventing costly downtime.

Decoding Your Probe: Model Number Details

Every part of the code 330101-48-71-20-02-CN tells you exactly what you're getting:

• 330101: 3300 XL Series, 8mm Diameter Probe, 3/8-24 UNF Thread, No Armor.
• 48: Unthreaded Probe Length = 4.8 inches.
• 71: Overall Case Length = 7.1 inches.
• 20: Total Integrated Cable Length = 2.0 meters (6.6 feet).
• 02: Connector Type = Miniature Coaxial ClickLoc with Standard Cable.
• CN: Country-Specific Configuration (e.g., documentation, special markings).

Essential Technical Performance Data

• Electrical Output: -1 to -17 Vdc over linear range.
• Linear Measurement Range: 2.0 mm (80 mils), from 0.25 mm to 2.3 mm.
• Optimal Gap Setting (Radial): -9 Vdc (approx. 1.27 mm / 50 mils).
• System Sensitivity (Scale Factor): 7.87 V/mm (200 mV/mil) ±5%.
• Probe Resistance (2m length): 7.88 Ω ±0.50 Ω.
• Cable Specification: Capacitance 69.9 pF/m (typical).
• Extended Reach: Field wiring up to 305 meters (1000 ft) to monitor.
• Mechanical Strength: CableLoc design provides 330 N (75 lbf) pull-off resistance.
• High-Temperature Operation: Standard range: -52°C to +177°C (-62°F to +350°F).
• Robust Construction: PPS Plastic Tip with AISI 303/304 Stainless Steel Case.

Core Features & Key Benefits

• Unmatched Durability: The 8mm diameter provides a thicker, stronger body for superior resistance to physical stress and vibration.
• Patented Reliability: TipLoc molding creates an ultra-strong bond between the tip and body; CableLoc ensures the cable stays securely attached.
• Precision Measurement: Excellent linearity and a stable scale factor deliver accurate, repeatable data for condition monitoring.
• Long-Distance Compatibility: The 2-meter integrated cable and support for long field wiring offer flexible installation in large facilities.
• Industrial-Grade Sealing: Viton® O-ring provides a reliable pressure seal against contaminants.

Installation & System Integration

Install the 330101-48-71-20-02-CN probe easily into a standard 8mm threaded mounting hole. The 4.8-inch unthreaded section offers versatile positioning. Connect it directly to compatible Bently Nevada 3300 XL Proximitor sensors or extension cables using the secure ClickLoc connector. For optimal performance, always set the initial gap to achieve approximately -9 Vdc. Use recommended 3-conductor shielded cable for all field wiring to ensure signal integrity.

Expert FAQs

What is the main application for a probe with a 2-meter cable?

This length is ideal for installations where the monitoring cabinet is located further from the measurement point on the machine, reducing the need for additional extension cables and simplifying wiring.

Does the "CN" suffix affect the probe's technical performance?

No. The "CN" code typically relates to country-specific documentation, labeling, or customs requirements. The probe's electrical and mechanical specifications remain standard.

Can I replace a 5mm probe with this 8mm model?

You must check the mounting hole in your machinery. An 8mm probe requires an 8mm threaded hole. It cannot fit into a smaller 5mm hole without modification.

What is the difference between "standard" and "FluidLoc" cable?

The standard cable (option 02) is for general use. FluidLoc cable (option 12) has a special internal seal to prevent liquids from migrating through the cable core, which is critical in oily environments.

How does the CableLoc design benefit installation?

It mechanically locks the cable to the probe, providing extremely high pull-out resistance (75 lbf). This prevents accidental disconnection from vibration or handling, ensuring a permanently reliable connection.
