BENTLY NEVADA 330101-00-32-10-02-05 Proximity Probe

The Bently Nevada 330101-00-32-10-02-05, also cataloged as the 3300 XL 8 mm Probe, serves as the primary proximity sensor utilized to execute non-contact shaft position and vibration measurements across 3500 and 3300 Machinery Protection System platforms.

Hardware Specifications

Eddy-Current Probe Scaling & Rotor Dynamics

The 330101-00-32-10-02-05 operates via high-frequency eddy-current electromagnetic fields to track dynamic rotor behavior without mechanical contact. Precise output scaling demands gap voltage validation targeting nominal -10 VDC baseline setting at the center of the calibrated linear range. Advanced internal shielding and tip design offer cross-talk suppression during close-proximity dual-probe mounting on journal bearings, allowing accurate monitoring of shaft position, thermal expansion, and severe rotor dynamic instabilities.

Frequently Asked Questions

Q: What is the physical significance of the 32 option in the overall case length?

A: Option 32 designates an overall case length of 3.2 inches, fully threaded with 0.0 inches unthreaded length (Option 00) for direct mechanical mounting into bearing housings.

Q: How is the coaxial cable secured against accidental disengagement caused by machine vibration?

A: The probe utilizes a miniature coaxial ClickLoc connector designed to physically lock into place, providing a reliable electrical connection under high continuous vibration levels.

Field Installation Guidelines

• Thread the probe body using the 3/8-24 UNF threads into the mounting port, ensuring a minimum of 5 full thread turns engagement for structural stability.
• Set the physical mechanical gap by measuring the DC output voltage at the Proximitor sensor until it reaches the nominal -10 VDC target.
• Ensure ClickLoc coaxial connectors are fully mated until the mechanical locking detent visually and physically engages.
• Route extension cables through dedicated grounded conduits, separated from high-voltage motor power wiring by a minimum of 300 mm.
