330101-00-08-10-02-05 | Bently Nevada 8 mm Probe 1.0 m Cable

Introduction to the 330101-00-08-10-02-05

When machinery reliability is critical, the 330101-00-08-10-02-05 from Bently Nevada provides accurate displacement measurements. This 3300 XL 8 mm probe features a 3/8-24 UNF thread and a 1.0 m cable with a miniature coaxial ClickLoc connector. It is designed for continuous monitoring in harsh industrial environments.

Key Features and Technical Specs

• Probe Type: 3300 XL 8 mm, unarmored, with 3/8-24 UNF thread.
• Linear Range: 2 mm (80 mils) from 0.25 mm to 2.3 mm from target.
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5% for 1.0 m system.
• Probe Tip Material: Polyphenylene sulfide (PPS) for durability.
• Probe Case Material: AISI 303 or 304 stainless steel.
• Temperature Range: -52°C to +177°C standard probe.
• Approvals: CSA, ATEX, IECEx certified.

The patented TipLoc molding method ensures a robust bond between tip and body, while CableLoc design provides 330 N (75 lbf) pull strength. These features enhance reliability in rotating machinery applications.

Applications and Use Cases

This probe is ideal for radial vibration and thrust position monitoring in turbines, compressors, and pumps. Its 2 mm linear range covers typical shaft displacement requirements. The ATEX and IECEx approvals allow use in hazardous areas. For example, in a gas compressor installation, the 330101-00-08-10-02-05 provides consistent -9 Vdc output at the recommended gap setting.

Installation and Setup

Mount the probe with the recommended gap of -9 Vdc (approximately 1.27 mm). Use 3-conductor shielded triad cable for field wiring, with maximum length of 305 meters to the monitor. Ensure the probe tip is clean and the target surface is smooth. Follow the manufacturer's manual for proper torque on the 3/8-24 UNF threads.

Maintenance and Reliability

Inspect the probe cable and connector periodically for damage. The PPS tip resists chemical exposure, and the stainless steel case withstands corrosion. Operate within the -52°C to +177°C range to avoid pressure seal failure. Regular calibration checks verify the incremental scale factor remains within ±5%.

Compatibility and Integration

The 330101-00-08-10-02-05 works with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures secure signal transmission. Use the standard 1.0 m system for most installations; longer cables require recalibration.

Troubleshooting and Common Issues

If output voltage drifts, check the gap setting and cable connections. High humidity may affect scale factor; the probe shows less than 3% change after 56 days at 93% humidity. For persistent errors, verify field wiring length does not exceed 305 meters.
