Description

The Bently Nevada 330101-00-30-10-11-00 is a specialized configuration of the 3300 XL 8 mm series proximity probe, featuring a 3/8-24 UNF unarmored threaded body with 0.0 inches of unthreaded length and a 3.0-inch overall case length. This specific variant is equipped with a 1.0-meter integrated FluidLoc cable, which provides exceptional resistance against fluid and oil migration along the internal conductor. It is terminated with a miniature coaxial ClickLoc connector complete with an integrated connector protector, and is configured without hazardous area agency approval requirements. By pairing this precise configuration with a 3300 XL Proximitor sensor and a compatible extension cable, users can establish a high-accuracy, non-contacting eddy-current measurement path for machinery protection and condition monitoring.

As part of the 3300 XL 8 mm Proximity Transducer System, this probe is engineered for long-term reliability in harsh industrial environments such as steam turbines, gas turbines, compressors, pumps, and gearboxes. The system provides a static and dynamic voltage output directly proportional to the distance between the probe tip and the observed target (typically AISI 4140 steel). With its rugged Polyphenylene Sulfide (PPS) tip and robust stainless steel case construction, it delivers outstanding mechanical protection and thermal stability, maintaining interchangeable accuracy without the need for individual component calibration.

Features

• Fully Threaded Case: Engineered with 0.0 inches of unthreaded length and a 3.0-inch overall case length, allowing maximum adjustment depth inside threaded mounting ports.
• FluidLoc Cable: Designed with specialized sealing to prevent lube oil or other process fluids from leaking out of the machine through the cable interior.
• ClickLoc Connector with Protector: Features a gold-plated ClickLoc coaxial connector equipped with a factory-installed connector protector to seal out moisture and contaminants at the junction point.
• Unarmored Design: A streamlined, lightweight unarmored configuration suitable for installations where protective conduit or existing ducting is already utilized.
• Complete Interchangeability: Seamlessly integrates within standard 3300 XL 8 mm monitoring chains, including Proximitor sensors and extension cables, without requiring recalibration.

Applications

This proximity probe is ideal for high-precision machinery protection and vibration monitoring across heavy industrial sectors, including power generation, petrochemicals, and water treatment. Typical applications include:

• Radial vibration and shaft dynamic displacement monitoring on steam and gas turbines.
• Axial thrust position and rotor movement tracking in high-pressure compressors and pumps.
• Eccentricity and speed measurement on critical rotating machinery.
• Keyphasor phase reference and rotational speed monitoring.
• Environments requiring high resistance to lubricant oil migration (utilizing the FluidLoc cable).

Installation Guidelines

To ensure high measurement accuracy and long-term reliability of the Bently Nevada 330101-00-30-10-11-00, observe the following engineering guidelines during installation:

• Probe Gap Setting: Mount the probe with the appropriate gap distance from the target. For standard radial vibration monitoring, set the target gap to approximately 1.27 mm (50 mils), which corresponds to a DC output of -9 Vdc when connected to the Proximitor sensor.
• Thread Engagement: Do not exceed the maximum recommended thread engagement length of 0.563 inches for 3/8-24 threads, as excess engagement can cause binding or damage.
• Cable Routing: Ensure the FluidLoc probe cable is routed away from moving machinery components. Avoid sharp bends; maintain a minimum bend radius of 25.4 mm (1.0 inch) to prevent internal conductor damage.
• Shielding and Grounding: Properly shield the coaxial cable and terminate the outer shield braid to the system ground at the monitor or Proximitor housing side only. Avoid multi-point ground loops.
• Connector Protection: Ensure the pre-installed connector protector is fully seated over the ClickLoc coaxial connection to prevent moisture, dirt, and oil contamination.

Compliance and Certifications

The standard industrial configuration (Option E = 00) is manufactured to Bently Nevada's high quality standards. For standard non-hazardous applications, compliance includes:

• CE Compliant (when installed per system guidelines)
• RoHS compliant
