330141-08-10-11-00 Bently Nevada 3300 XL 8 mm Probe

Case Study: Solving High-Vibration Measurement Challenges

A petrochemical plant faced frequent false trips on a critical compressor due to probe damage in a high-vibration environment. The existing probes lacked mechanical robustness, causing cable pull-out and signal degradation. The solution was the Bently Nevada 330141-08-10-11-00, a 3300 XL 8 mm probe with armor. This probe's patented TipLoc and CableLoc designs provide a robust bond and 330 N (75 lbf) pull strength, eliminating cable detachment. Consequently, the plant achieved reliable, continuous vibration monitoring, reducing unplanned downtime.

Product Overview

The 330141-08-10-11-00 is a Bently Nevada 3300 XL 8 mm probe with armor, designed for precise displacement and vibration measurements in industrial machinery. Manufactured in the U.S.A., it features a 1.0 meter (3.3 feet) total length and a miniature coaxial ClickLoc connector with standard cable. The 8 mm probe diameter offers thicker encapsulation of the probe coil in a molded PPS plastic tip, resulting in a more rugged probe. The larger body diameter provides a stronger, more robust case, making it ideal for applications where physical abuse is a concern.

Key Features & Technical Specifications

• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for 1 m system, ensuring accurate measurements.
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) for 1 m system, providing high linearity.
• Probe Tip Material: Polyphenylene sulfide (PPS) for durability and chemical resistance.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) for corrosion resistance.
• Operating Temperature: Standard probe: -52°C to +177°C (-62°F to +350°F).
• Nominal Probe DC Resistance: 7.59 ± 0.50 Ω for 1.0 m probe length.
• Connector: Miniature coaxial ClickLoc connector, standard cable.
• Agency Approval: CSA, ATEX, IECEx approvals.

These specifications ensure engineering-grade precision in every part, with exact electrical characteristics for reliable system integration.

Applications and Use Cases

The 330141-08-10-11-00 excels in turbomachinery applications, such as steam turbines, compressors, and pumps. Its robust design suits high-vibration environments where standard probes fail. Additionally, the probe's pressure sealing capability with a Viton O-ring allows use in differential pressure applications. The armored construction protects against mechanical damage, extending service life. Therefore, it is a preferred choice for oil and gas, power generation, and petrochemical industries.

Installation and Maintenance

Install the probe according to Bently Nevada guidelines, ensuring proper mounting and clearance. The ClickLoc connector simplifies cable attachment. For maintenance, inspect periodically for physical damage and verify signal integrity. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. Regular checks help maintain measurement accuracy and system reliability.
