Description

The Bently Nevada 330101-00-40-10-02-00 is an unarmored 3300 XL 8 mm proximity probe configured with 0.0 inches of unthreaded case length, a 4.0-inch overall case length, and a 1.0-meter (3.3 feet) total cable length. This configuration is equipped with a miniature coaxial ClickLoc connector on a standard cable and is designed for applications where specialized agency approvals are not required. It operates on the eddy current principle to deliver reliable, non-contact shaft displacement and vibration measurements on critical industrial rotating machinery.

By pairing this probe with a compatible 3300 XL Proximitor sensor and extension cable, operators can implement a robust machinery protection chain. The unarmored design simplifies installation in standard conduit-protected or enclosed bearing housings, while the 4.0-inch fully threaded case provides a substantial adjustment range for optimizing the probe's gap relative to the target shaft. This specific option combination is well-suited for standard, non-hazardous industrial environments where robust electrical insulation and straightforward mechanical integration are primary requirements.

Features

• Optimized Threaded Case: Fully threaded 4.0-inch (3/8-24 UNF) case length with 0.0 inches unthreaded, offering versatile positioning within bearing housings.
• Standard Non-Armored Cable: Features a 1.0-meter standard cable, providing low-noise transmission without the added bulk of steel armoring.
• ClickLoc Coaxial Connection: Equipped with a gold-plated miniature ClickLoc coaxial connector to ensure robust electrical contact and high vibration resistance.
• Eddy Current Measurement Principle: Delivers linear, non-contact measurement of shaft vibration and position with high accuracy.
• Rugged Material Construction: Polyphenylene Sulfide (PPS) probe tip and stainless steel probe body survive high-temperature and high-pressure industrial environments.

Applications

The Bently Nevada 330101-00-40-10-02-00 is widely utilized across heavy industrial sectors to monitor rotating shaft health. Typical applications include:

• Steam and gas turbine shaft radial vibration and axial position monitoring.
• Centrifugal and reciprocating compressor rotor displacement detection.
• Boiler feed pump shaft alignment and thermal expansion tracking.
• General machinery protection in non-hazardous plant environments where standard electrical certifications suffice.

Installation Guidelines

To ensure precise performance and minimize measurement error, adhere to these key installation standards:

• Mechanical Gapping: Adjust the physical spacing between the probe tip and the target shaft using a calibration multimeter or voltage check on the Proximitor sensor output to achieve the standard linear range (typically -10 Vdc at mid-gap).
• Cable Shielding and Grounding: Ensure the coaxial cable shield is isolated from the machine housing and correctly grounded at the Proximitor terminal or instrument rack panel to eliminate electromagnetic interference.
• Avoid Side-Wall Interference: Maintain a minimum radial clearance around the 8 mm tip of at least 3 times the probe diameter to prevent proximity interference from bearing housing walls.
• Torque Limits: Do not exceed the maximum tightening torque of 11.2 N-m (100 in-lb) for 3/8-24 threaded probes during final locknut tightening.
