330140-10-20-11-CN Bently Nevada 3300 XL 8 mm Probe 2.0 m

Introduction: The Evolution of Precision Measurement

Industrial machinery has evolved from simple mechanical linkages to high-speed turbomachinery operating at extreme tolerances. As rotating equipment became more complex, the need for exact vibration monitoring grew. Early sensors often failed under harsh conditions, leading to unplanned downtime. Consequently, Bently Nevada developed the 3300 XL series to meet these demanding requirements. The 330140-10-20-11-CN represents this engineering-grade precision. It is a non-armored 8 mm probe designed for reliable shaft displacement measurement.

330140-10-20-11-CN Key Features and Specifications

This probe utilizes a patented TipLoc molding method, which creates a robust bond between the tip and body. Additionally, the CableLoc design provides 330 N (75 lbf) of pull strength. The 330140-10-20-11-CN includes a FluidLoc cable option to prevent oil leakage. Its 2.0-meter total length offers flexibility in installation. The probe tip is made of polyphenylene sulfide (PPS), while the case uses AISI 303 or 304 stainless steel. The nominal DC resistance from center to outer conductor is 7.88 ± 0.50 Ω.

Installation and Integration

Proper installation ensures accurate data. First, mount the probe securely to avoid mechanical resonance. The 8 mm probe body provides a stronger case for robustness. Second, connect the ClickLoc connector carefully. The FluidLoc cable prevents liquid ingress through the cable interior. Therefore, it is ideal for oil-lubricated machines. Finally, verify the total length matches your requirement. The 330140-10-20-11-CN has a 2.0-meter length, suitable for many standard setups.

Applications and Use Cases

The 330140-10-20-11-CN excels in turbomachinery monitoring. For instance, it measures radial vibration on steam turbines. Additionally, it monitors axial position on centrifugal compressors. Its stainless steel case resists corrosion in harsh environments. The FluidLoc option further protects against oil leakage. Consequently, this probe is a reliable choice for continuous monitoring systems.

Maintenance and Reliability

Regular inspection ensures long-term reliability. Check the probe tip for wear or damage periodically. Verify cable integrity, especially near connectors. The operating temperature range for standard probes is -52°C to +177°C. However, avoid temperatures below –34°C, as this may cause premature seal failure. The 330140-10-20-11-CN is designed for durability. Its PPS tip and stainless steel case withstand demanding conditions.
