Introduction to the 330140-08-20-11-00
When machinery vibration threatens uptime, engineers need a reliable measurement solution. The Bently Nevada 330140-08-20-11-00 3300 XL 8 mm probe delivers precise shaft vibration data in demanding industrial environments. This probe, manufactured in the U.S.A., is part of the trusted 3300 XL series known for robust performance.
With an overall case length of 0.8 inches and a total length of 2.0 meters (6.6 feet), this probe fits a variety of mounting configurations. The miniature coaxial ClickLoc connector with connector protector and FluidLoc cable ensures secure, leak-resistant connections. This design simplifies installation and maintenance, reducing downtime.
Technical Specifications and Performance
The 330140-08-20-11-00 offers an incremental scale factor (ISF) of 7.87 V/mm (200 mV/mil) with ±5% interchangeability error over the 80 mil linear range. This accuracy holds from 0°C to +45°C (+32°F to +113°F), ensuring consistent readings in typical operating conditions. The deviation from the best fit straight line (DSL) is less than ±0.025 mm (±1 mil) for standard 5 or 1 meter systems, providing high measurement fidelity.
Key specifications include:
- Probe tip material: Polyphenylene sulfide (PPS)
- Probe case material: AISI 303 or 304 stainless steel (SST)
- Probe weight: 323 g/m (11.4 oz)
- Operating and storage temperature: -52°C to +177°C (-62°F to +350°F)
- Nominal probe DC resistance: 7.88 ± 0.50 ohms (for 2.0 m length)
The probe's rugged construction includes a patented TipLoc molding method for a robust bond between tip and body. The CableLoc design provides 330 N (75 lbf) pull strength, securing the cable and tip. These features minimize the risk of damage from vibration and physical abuse.
Application Scenarios and Use Cases
In rotating machinery such as turbines, compressors, and pumps, the 330140-08-20-11-00 monitors shaft vibration to detect early signs of imbalance or misalignment. Its stainless steel case and PPS tip withstand harsh conditions, while the FluidLoc cable option prevents oil leaks from the machine interior. This makes it ideal for applications where fluid ingress is a concern.
For example, in a typical petrochemical plant, this probe can be installed on a centrifugal compressor to provide continuous vibration data. The high accuracy and stability of the ISF ensure reliable trend analysis, helping maintenance teams schedule repairs before failures occur. The probe's temperature range covers most industrial environments, from cold outdoor installations to hot process areas.
Compatibility and Integration
The 330140-08-20-11-00 is designed for use with Bently Nevada 3300 XL monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, quick connection to extension cables and monitors. The 2.0-meter cable length provides flexibility in routing to the monitoring equipment.
This probe is compatible with standard 3300 XL extension cables and proximity transducer systems. The connector protector shields the connection from contaminants, maintaining signal integrity. For systems requiring extended temperature ranges, optional ETR probes are available, but this model operates within the standard range.
Business Value and ROI
Investing in the 330140-08-20-11-00 reduces total cost of ownership by minimizing unplanned downtime. Accurate vibration data enables predictive maintenance, extending machinery life and avoiding catastrophic failures. The rugged design reduces replacement frequency, and the easy installation cuts labor costs.
With a pull strength of 330 N, the cable resists damage from pulling or vibration, reducing maintenance interventions. The FluidLoc option prevents oil leaks, protecting the environment and avoiding cleanup costs. These benefits translate into measurable savings for plant operators.
Frequently Asked Questions
What is the linear range of the 330140-08-20-11-00?
The probe has an 80 mil linear range, over which the incremental scale factor is specified. This range is sufficient for most shaft vibration measurements in industrial machinery.
Can the 330140-08-20-11-00 be used in high-temperature environments?
The standard probe operates from -52°C to +177°C (-62°F to +350°F). For higher temperatures, consider an extended temperature range probe, but this model is suitable for most applications.
What is the significance of the FluidLoc cable option?
The FluidLoc cable prevents oil and other liquids from leaking out of the machine through the cable interior. This is critical in applications where fluid containment is required.
How does the probe's accuracy compare to other models?
The 330140-08-20-11-00 offers an ISF of 7.87 V/mm with ±5% interchangeability error, which is standard for 3300 XL 8 mm probes. This accuracy ensures reliable measurements across different installations.
Is the 330140-08-20-11-00 easy to install?
Yes, the miniature coaxial ClickLoc connector simplifies installation and removal. The 2.0-meter cable provides adequate length for routing, and the connector protector keeps the connection clean.
