330701-00-24-50-12-00 Bently Nevada 3300 XL 11 mm Proximity Sensor Probe

Product Overview

The 330701-00-24-50-12-00 is an advanced 3300 XL 11 mm Proximity Probe engineered by Bently Nevada. This large-tip 3300 XL Series transducer system offers extended linear measurement range and exceptional signal stability for critical rotating machinery monitoring applications.

Technical Specifications Matrix

Configuration Breakdown and Suffix Codes

• Model 330701: 3300 XL 11 mm Probe, 1/2-20 UNF thread without armor
• Unthreaded Length Option (-00): 0 inches unthreaded body portion
• Overall Case Length Option (-24): 2.4 inches total probe case length
• Total Length Option (50): 5.0 meters (16.4 feet) system cable length (exclusive for 5m Proximitor)
• Connector & Cable Type (-12): Miniature coaxial ClickLoc connector with FluidLoc cable
• Agency Approval (-00): Not required / standard industrial grade

Installation Guide

Screw the 1/2-20 UNF probe case into the machinery mounting port, restricting thread engagement to a maximum of 0.750 inches. Apply a recommended installation torque of 15.2 N·m (133 in·lb) using proper wrench flats. Ensure the 5-meter FluidLoc cable is routed cleanly with a bend radius no tighter than 25.4 mm (1.0 in).

Commissioning and Maintenance Convenience

Verify that the 5-meter probe is paired explicitly with a matching 5-meter Proximitor sensor to maintain calibration accuracy. FluidLoc cable construction blocks oil wick migration through the core during long-term operation. ClickLoc connectors allow fast, tool-free locking during routine loop checks.

Compatibility Notes

This 11 mm probe requires specific 3300 XL 5-meter driver components. It replaces legacy 8 mm and 11 mm sensor setups where broader linear range or higher target clearance is necessary.

Certifications and Warranty Terms

Built in the United States under rigorous quality controls. Backed by a standard 12-month factory warranty covering component and workmanship defects.

Shipping and Logistics

Global fulfillment executed via carriers including FedEx, UPS, and DHL. Stocked inventory dispatches within 24 to 48 hours to prevent facility delays.

Application Scenarios and Diagnostics

Deployed widely on large steam turbines, heavy hydroelectric generators, and high-capacity centrifugal compressors experiencing significant thermal growth. System diagnostic routines identify open circuit faults, shorted coaxial layers, and abnormal gap voltages via monitoring rack outputs.

Global PLC Spare HUB's Insight

Our automation specialists implemented the 330701-00-24-50-12-00 on a high-temperature boiler feed pump subject to severe vibration shifts. The 11 mm tip profile provided a wider linear range than standard 8 mm probes, while the FluidLoc cable completely eliminated oil leakage tracking into the junction box.

Technical Comparison & Model Selection

When selecting 11 mm assemblies, verify that your system architecture utilizes compatible 5-meter extension pairings rather than standard 1-meter configurations to avoid calibration scaling errors.

Frequently Asked Questions

Q: What specific operational issue occurs if this 5-meter probe is paired with a 1-meter Proximitor sensor?

A: Resistance mismatches will alter the incremental scale factor, leading to severe measurement inaccuracy and false vibration alarms.

Q: Why does the FluidLoc cable design matter in heavy industrial environments?

A: It incorporates internal barriers that stop oil and synthetic lubricants from wicking through the cable jacket into the terminal housing.

Q: What mechanical precaution prevents thread galling during 1/2-20 probe installation?

A: Ensure the mounting threads are clean, adhere strictly to the 15.2 N·m recommended torque limit, and avoid exceeding the 0.750-inch engagement limit.

Q: How does the 11 mm tip diameter alter performance compared to standard 8 mm probes?

A: The larger tip diameter expands the linear operating range, making it ideal for machinery with high shaft radial runout.

Q: Is a factory pressure seal test performed on this probe prior to dispatch?

A: Probes are not pressure tested by default before shipping; request special custom design department verification if your process requires a certified pressure boundary test.
