330140-10-20-11-00 Bently Nevada 3300 XL 8 mm Probe

Problem: Harsh Machine Environments Degrade Probe Reliability

Industrial machinery exposes eddy current probes to vibration, moisture, and physical abuse. The Bently Nevada 330140-10-20-11-00 addresses these failure modes through engineering-grade design. This 3300 XL 8 mm probe without armor delivers precise displacement measurement for critical turbomachinery.

Solution: 330140-10-20-11-00 Construction and Specifications

The probe features a patented TipLoc molding method that creates a robust bond between the probe tip and body. Additionally, the CableLoc design provides 330 N (75 lbf) pull strength, preventing cable detachment during high-vibration operation.

Key technical parameters include:

• Total Length: 2.0 meters (6.6 feet)
• Connector Type: Miniature coaxial ClickLoc with protector
• Cable Option: FluidLoc, prevents liquid leakage
• Probe Tip Material: Polyphenylene sulfide (PPS)
• Case Material: AISI 303 or 304 stainless steel
• Nominal DC Resistance: 7.88 ± 0.50 Ω
• Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±5%
• Operating Temperature: -52°C to +177°C (-62°F to +350°F)

Problem: Cable Degradation and Fluid Ingress

Oil and other liquids can leak through cable interiors, causing signal faults. The FluidLoc cable option on the 330140-10-20-11-00 prevents this leakage path. Consequently, the probe maintains signal integrity in lubricated bearing housings.

Solution: FluidLoc Cable and ClickLoc Connector

The miniature coaxial ClickLoc connector includes a connector protector. This design ensures secure mating and reduces strain on the connection point. The 2.0 meter cable length suits typical machine-mounted installations.

Problem: Physical Abuse Reduces Probe Lifespan

Thinner probes are more susceptible to damage during installation and operation. The 8 mm probe body provides a thicker encapsulation of the probe coil in molded PPS plastic. As a result, the probe withstands greater physical abuse.

Solution: Rugged 8 mm Probe Body

Bently Nevada recommends 8 mm probes for optimal robustness. The stainless steel case adds further durability. This engineering-grade construction ensures reliable performance in demanding environments.
