330141-08-90-11-05 Bently Nevada 3300 XL 8 mm Probe

Problem: Harsh Machine Environments Destroy Standard Probes

Industrial turbines and compressors subject eddy-current probes to constant vibration, abrasion, and fluid ingress. Standard probes fail prematurely when their tip-to-body bond weakens or cable pull strength drops. The Bently Nevada 330141-08-90-11-05 solves this with a patented TipLoc molding method and CableLoc design that provides 330 N (75 lbf) pull strength. Consequently, the probe remains mechanically stable throughout extended service.

What Is the 330141-08-90-11-05?

This is a 3300 XL 8 mm probe with armor, manufactured by Bently Nevada. The 8 mm diameter provides thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged tip. Meanwhile, the larger probe body offers a stronger case against physical abuse. The 9.0-meter (29.5-foot) total length suits long cable runs between the probe and extension cable. Additionally, the FluidLoc cable option prevents oil and other liquids from leaking through the cable interior.

Key Specifications for Engineering-Grade Accuracy

• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±6.5% for 9-meter systems.
• Deviation from best fit straight line: Less than ±0.038 mm (±1.5 mil).
• Nominal probe DC resistance: 9.87 ±0.50 Ω at 9.0 meters.
• Probe tip material: Polyphenylene sulfide (PPS).
• Probe case material: AISI 303 or 304 stainless steel.
• Probe weight: 323 g/m (11.4 oz).
• Operating temperature: -52°C to +177°C (-62°F to +350°F) for standard probe.
• Connector: Miniature coaxial ClickLoc with protector.

Each value is verified against the manufacturer's specification, ensuring engineering-grade precision in every part.

Problem: Cable Pull-Out and Fluid Leakage

Vibration can pull standard probe cables from their connectors. The 330141-08-90-11-05 addresses this with 330 N (75 lbf) pull strength from the CableLoc design. Furthermore, the FluidLoc cable option blocks oil from escaping through the cable interior. As a result, the probe maintains signal integrity even in oil-mist environments. The miniature coaxial ClickLoc connector with protector adds another layer of security against accidental disconnection.

Problem: Temperature Extremes and Humidity

Standard probes may drift when exposed to temperature swings or high humidity. This probe operates from -52°C to +177°C for the standard tip. The Viton O-ring seals differential pressure between tip and case. Additionally, the probe exhibits less than a 3% change in Average Scale Factor when tested at 93% humidity for up to 56 days. Therefore, it maintains measurement accuracy in tropical or wash-down areas.

Installation and Compatibility

Install the probe according to Bently Nevada 3300 XL system guidelines. Use the 9.0-meter length to reach extension cables without signal degradation. The ClickLoc connector mates with standard 3300 XL extension cables. For precise matching with your monitoring system, contact AutoDCSTech with your exact requirements.
