330101-00-67-10-12-CN | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-67-10-12-CN represents a specialized, extra-long reach transducer within the Bently Nevada 3300 XL system. This 100% Brand New original 8mm probe monitors radial vibration, axial thrust, and shaft position on fluid-film bearing machines. Manufactured in the U.S.A., it translates mechanical displacement into a high-precision electrical signal for critical machinery protection. This configuration features an exceptional 6.7-inch threaded case and a 1.0-meter Fluid-Loc™ cable, providing the reach and environmental sealing required for deep-access installations where oil migration through the cable must be prevented.

Technical Specifications

The 330101-00-67-10-12-CN utilizes high-grade materials to maintain signal linearity and mechanical integrity in aggressive industrial zones.

Engineering Advantages

• Extreme Case Length for Deep Cavities: The 6.7-inch threaded case enables the probe to reach shaft targets through exceptionally thick machine casings or internal bearing pedestals. This length provides the necessary reach for large-scale utility turbines without requiring custom-manufactured mounting sleeves.

• Fluid-Loc™ Anti-Wicking Technology: The "-12" cable option utilizes Fluid-Loc™ technology to prevent oil or other liquids from wicking through the inside of the cable. This feature protects the Proximitor sensor and junction boxes from oil contamination, even if the probe end remains submerged in a pressurized bearing housing.

• Vibration-Proof ClickLoc™ Connection: The miniature coaxial ClickLoc™ connector incorporates a positive-locking mechanism. This prevents unintentional cable disconnection or signal attenuation caused by high-frequency machinery vibrations, a critical requirement for continuous monitoring uptime.

• High-Temperature Resilience: The PPS tip and stainless steel construction withstand the high temperatures and corrosive lubricants typical of steam turbine environments. The probe maintains a stable electrical gap setting across its entire thermal operating envelope.

FAQs

• Is this 330101-00-67-10-12-CN probe a brand-new unit?

  Yes. We supply this probe exclusively as 100% Brand New original factory stock. Each unit arrives in Bently Nevada’s original protective packaging with the "Made in U.S.A." designation to guarantee authenticity and field performance.

• Which extension cable should I pair with this 1.0-meter probe?

  To achieve a standard 5.0-meter system length, you must pair this 1.0-meter probe with a 4.0-meter 3300 XL extension cable. For a 9.0-meter system, pair it with an 8.0-meter extension cable. Ensure the total electrical length matches the calibration of your Proximitor sensor.

• What is the significance of the -CN suffix?

  The -CN suffix indicates that the probe complies with specific regional regulatory and certification requirements for the China market. This hardware maintains the same global performance specifications as standard 3300 XL probes while meeting local compliance standards.

• How do I set the correct mechanical gap during installation?

  Adjust the 3/8-24 UNF threading while monitoring the DC Gap voltage at the Proximitor output. For most standard applications, a voltage reading of approximately -10.0 VDC indicates the center of the probe's linear measurement range.
