Bently Nevada 330101-00-39-15-11-CN 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330101-00-39-15-11-CN is a high-performance 3300 XL 8 mm proximity probe engineered for superior reliability in rotating machinery monitoring. Proudly Made in the U.S.A., this model features a 3/8-24 UNF thread and the specialized FluidLoc cable, which prevents oil and process liquids from leaking out of the machine through the cable interior. Utilizing patented TipLoc and CableLoc technologies, this probe offers a robust bond and a 330 N (75 lbf) pull strength, ensuring maximum physical durability in demanding industrial environments.

Technical Specifications

Mechanical Design & Operational Benefits

1. Ruggedized Construction: The 8 mm probe body is designed with a thicker PPS plastic encapsulation for the coil, providing enhanced protection against physical abuse compared to smaller sensors. The 3.9-inch stainless steel case (AISI 303/304) is fully threaded for versatile mounting, and despite its heavy-duty build, the cable remains manageable with a weight of 323 g/m.

2. FluidLoc Leak Protection: This specific configuration includes the FluidLoc cable option. This is a critical safety feature for process compressors and pressurized machines, as it effectively blocks the "wicking" effect where oils or gases travel through the internal gaps of a standard cable, leaking into the external environment.

3. Advanced Connectivity: The probe features a miniature coaxial ClickLoc connector equipped with a connector protector. This safeguard prevents environmental contaminants and moisture from compromising the gold-plated electrical contacts, ensuring long-term signal stability even in 93% relative humidity conditions.

Installation Guidelines

Gap Setting: The recommended gap for radial vibration is -9 Vdc [approx. 1.27 mm (50 mils)]. The linear range is approximately -1 to -17 Vdc, starting at 0.25 mm from the target. For the best accuracy, use a three-conductor shielded triad cable for field wiring to the monitor.

Torque Limits: For 3/8-24 threaded cases, Bently Nevada recommends a nominal installation torque. Ensure the mounting is secure but avoid over-torquing, which could impact the internal pressure seal. Note that exposing the probe to temperatures below -34°C may affect the longevity of the Viton® O-ring seal.

Signal Integrity: To ensure high-frequency accuracy, the maximum field wiring length between the Proximitor Sensor and the monitor should be limited to 305 meters (1,000 feet) to prevent signal roll-off.

Technical FAQs

Q: What is the benefit of the -11 cable option?
A: It combines the ClickLoc connector (for secure fit), a connector protector (for moisture sealing), and FluidLoc technology (to prevent oil leakage through the cable).

Q: Is this probe compatible with standard 3300 XL Proximitor Sensors?
A: Yes, it provides the standard 7.87 V/mm (200 mV/mil) scale factor and is fully compatible with the 3300 XL 5-meter and 9-meter systems.

Q: Can I request a Certificate of Origin for this item?
A: Absolutely. Since this product is manufactured in the U.S.A., a formal Certificate of Origin (COO) can be provided upon request to satisfy international trade or project requirements.
