Product Overview

The Bently Nevada 330104-01-09-10-12-05 belongs to the 3300 XL 8mm Proximity Transducer System, the most advanced eddy current sensor platform for vibration and position monitoring in rotating machinery. This specific 3/8-24 UNF thread probe delivers high-resolution measurement of shaft vibration, axial position, and speed by generating an electromagnetic field that interacts with the target material. Engineered for the demanding environments of steam turbines, compressors, and pumps, this probe ensures thermal stability and linear accuracy across a wide temperature range. It integrates seamlessly with the 3500/42M or 3500/40M monitors to provide critical machinery protection and diagnostic data.

Configuration Breakdown

Suffix Interpretation

• -10 (Total Length): 1.0 meter (3.3 feet).

• -12 (Connector/Adapter Option): Miniature coaxial ClickLoc connector with FluidLoc cable seal.

• -05 (Agency Approval): Multiple Approvals (ATEX, IECEx, CSA) for hazardous area installations.

Performance & Physical Specifications

On-Site Installation Intelligence

Precise installation is vital for signal integrity. Ensure the probe gap is set using the DC voltage method via the Proximitor Sensor output; typically, a center-gap voltage of -10 Vdc corresponds to the middle of the linear range. The ClickLoc connectors must be finger-tight; do not use pliers, as over-tightening damages the gold-plated contacts. For applications involving high-pressure oil or coolant, verify the FluidLoc seal integrity to prevent fluid wicking through the cable. Maintain a minimum bend radius of 25.4 mm (1 inch) for the coaxial cable to avoid impedance mismatches or signal attenuation.

Critical Engineering Assets

This 3300 XL probe offers superior chemical resistance and mechanical durability compared to previous generations. The PPS (Polyphenylene Sulfide) tip is gold-molded to the probe body, creating a leak-proof seal capable of withstanding high-pressure differentials. Its advanced "ClickLoc" connector system provides a positive locking mechanism that prevents disconnection due to machine vibration, while the gold-plated contacts ensure low-noise signal transmission for high-frequency vibration analysis. It is fully backwards compatible with 3300 5mm and 8mm systems when used with the appropriate Proximitor.

Field Support FAQs

Q1: Can I use this 1.0-meter probe with a 9.0-meter extension cable?

A1: No. The total system length must match the Proximitor calibration. This 1.0m probe must be paired with a 4.0m extension cable to work with a 5.0m Proximitor, or an 8.0m extension cable for a 9.0m Proximitor.

Q2: What is the significance of the "FluidLoc" option in the suffix?

A2: The FluidLoc seal prevents oil or other liquids from leaking out of the machine housing through the interior of the probe cable, which is essential for maintaining a vacuum or pressure seal in turbines.

Q3: How do I verify if the probe tip is damaged?

A3: Check the "Gap Voltage" output. If the voltage remains at the supply limit (typically -24V) or zero despite physical adjustment, the probe coil or cable may have an open or short circuit.

Q4: Is a specialized tool required for the 3/8-24 UNF threads?

A4: Standard SAE wrenches are used for mounting, but we recommend using a Bently Nevada probe housing or a specialized bracket to ensure the probe remains perpendicular to the shaft target area.
