Product Introduction
The Bently Nevada 330141-08-90-12-00 3300 XL 8 mm Probe with armor is engineered to address common failure modes in industrial vibration monitoring: cable pullout, oil leakage, and physical abuse. Part of the 3300 XL series, this probe incorporates patented TipLoc and CableLoc technologies that provide 330 N (75 lbf) pull strength and a robust tip-to-body bond. A FluidLoc cable option prevents fluid wicking, ensuring long-term integrity in lubricated machinery. With an overall case length of 0.8 inches and a total cable length of 9.0 meters (29.5 feet), the 330141-08-90-12-00 is designed for reliable operation in the most demanding industrial environments.
Technical Specifications
The Bently Nevada 330141-08-90-12-00 delivers precise performance parameters derived from its exact construction. Key specifications include:
-
Incremental Scale Factor (ISF): For the 9.0 meter system, the ISF is 7.87 V/mm (200 mV/mil) ± 6.5% including interchangeability error, measured in 0.25 mm increments over the 80 mil linear range from 0°C to +45°C (+32°F to +113°F).
-
Deviation from Best Fit Straight Line (DSL): Less than ±0.038 mm (±1.5 mil) with components at 0°C to +45°C (+32°F to +113°F) for the standard 9 meter system.
-
Nominal Probe DC Resistance (RPROBE): 9.87 ± 0.50 Ω for the 9.0 meter length.
-
Temperature Range: Standard probe operates from -52°C to +177°C (-62°F to +350°F); extended temperature range (ETR) probe covers -52°C to +218°C (-62°F to +425°F) for the tip and -51°C to +260°C (-60°F to +500°F) for cable and connector.
-
Probe Pressure Seal: Viton® O-ring designed for differential pressure; not pressure tested prior to shipment.
-
Relative Humidity: Less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days.
Installation & Setup Guidance
To maximize the failure-prevention benefits of the Bently Nevada 330141-08-90-12-00, proper installation is critical. Mount the probe in a straight bore with clearance for the armored cable. The ClickLoc miniature coaxial connector ensures a secure electrical connection without tools. When routing the FluidLoc cable, avoid sharp bends that could compromise the liquid seal. Ensure the probe tip is fully seated against the target surface and locked with the integral nut. For best linearity, the gap should be set within the 80 mil range. Do not expose the probe to temperatures below –34°C (–30°F) to prevent pressure seal failure.
Maintenance & Reliability
The 330141-08-90-12-00 is built for long service life with minimal maintenance. The PPS probe tip and 303/304 stainless steel case resist corrosion and physical wear. Regularly inspect the cable for kinks or abrasion, especially near the connector and machine entry point. Check the Viton O-ring seal if the probe is removed; replace if damaged. In high-humidity environments (up to 93% RH), the probe maintains ASF within 3% for over 56 days. For extended temperature applications (ETR version), ensure the cable connector does not exceed +260°C. Planned replacement intervals depend on operating conditions, but the rugged design typically exceeds five years in moderate use.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330141-08-90-12-00, verify compatibility with your monitoring system: it uses a miniature coaxial ClickLoc connector and FluidLoc cable. Confirm the total length (9.0 meters) meets your machine dimensions. The agency approval option (00) indicates standard non-certified model.
