330141-08-90-01-00 | Bently Nevada 3300 XL 8 mm Probe, 9.0 m

Product Overview: Bently Nevada 330141-08-90-01-00

The Bently Nevada 330141-08-90-01-00 is a 3300 XL 8 mm probe with armor, engineered for precise displacement and vibration measurement in rotating machinery. Manufactured in the U.S.A., this probe integrates a patented TipLoc molding method that creates a robust bond between the probe tip and body. Consequently, it delivers engineering-grade precision in demanding industrial environments. The 9.0-meter total length option supports extended reach from the machine casing to the monitoring system.

Unlike standard 5 mm probes, the 8 mm design provides thicker encapsulation of the probe coil within the molded PPS plastic tip. This results in a more rugged probe and a stronger case. Therefore, the 330141-08-90-01-00 is recommended when optimal robustness against physical abuse is required.

Key Specifications and Performance Data

The probe's electrical and mechanical parameters are verified for exact system integration. The nominal DC resistance from center conductor to outer conductor is 9.87 Ω ± 0.50 Ω at 9.0 meters. Moreover, the incremental scale factor (ISF) for a standard 9-meter system is 7.87 V/mm (200 mV/mil) ± 6.5%, measured over the 80 mil linear range from 0°C to +45°C. The deviation from best fit straight line (DSL) is less than ±0.038 mm (±1.5 mil) under the same conditions.

• Probe Tip Material: Polyphenylene sulfide (PPS)

• Probe Weight: 323 g/m (11.4 oz)
• Standard Operating Temperature: -52°C to +177°C (-62°F to +350°F)
• Connector Type: Miniature coaxial ClickLoc with protector, standard cable
• Agency Approval: 00 (not required)

Comparison with Alternative Probe Configurations

When selecting a probe for a 3300 XL system, engineers often compare the 8 mm armored model against unarmored or 5 mm variants. The 330141-08-90-01-00 offers distinct advantages:

• Armor Protection: The armored case shields the probe cable from mechanical damage, unlike unarmored probes.
• Probe Diameter: The 8 mm tip provides thicker coil encapsulation and a stronger case than 5 mm probes.
• Cable Retention: Patented CableLoc design provides 330 N (75 lbf) pull strength, exceeding typical cable attachments.
• Fluid Resistance: Optional FluidLoc cable prevents oil leakage, a feature not available on all probe models.

For applications requiring maximum robustness, the 8 mm armored probe is the preferred choice. However, if space is constrained, a smaller diameter probe may be necessary.

Installation and Maintenance Guidance

Install the probe according to the machinery manufacturer's specifications. Ensure the probe tip is positioned within the linear range and that the connector is properly seated. Because the probe operates with a Viton O-ring seal, avoid exposing it to temperatures below -34°C (-30°F), which may cause premature seal failure. Periodically inspect the armor and cable for wear, and verify the probe resistance to confirm integrity.
