330101-00-40-05-02-00 | Bently Nevada | 3300 XL 8mm Proximity Probe

Product Overview

The 330101-00-40-05-02-00 functions as a high-precision eddy-current transducer within the Bently Nevada 3300 XL ecosystem. This 100% Brand New original 8mm probe provides non-contacting measurement of radial vibration, axial thrust, and shaft position for fluid-film bearing machines. Manufactured in the U.S.A., it delivers the industry-standard 200 mV/mil scale factor required for critical machinery protection. This specific configuration features an extended 4.0-inch fully threaded case and a short 0.5-meter integral cable, making it the ideal choice for internal bearing housing installations where space for cable management is limited.

Technical Specifications

The 330101-00-40-05-02-00 utilizes high-grade materials to ensure signal linearity and mechanical resilience in aggressive industrial environments.

Engineering Advantages

• Extended Reach for Deep Access: The 4.0-inch threaded case enables the probe to reach internal shaft targets through thick machine casings or complex bearing housings. This long-reach design eliminates the need for custom mounting adapters, ensuring a direct and stable installation.

• Optimized Internal Routing: The 0.5-meter (1.6 feet) integral cable facilitates clean cable management inside the machine casing. This short length minimizes excess wire bulk, reducing the risk of cable snagging or vibration-induced wear within the oil-rich environment of the bearing housing.

• Vibration-Proof ClickLoc™ Connection: The ClickLoc™ miniature coaxial connector features a positive mechanical lock. This design prevents the cable from backing out due to high-frequency machinery vibrations, a common cause of "intermittent signal" or "Not OK" status in standard friction-fit systems.

• Superior Signal-to-Noise Ratio: High-performance cable shielding rejects electromagnetic interference (EMI) from nearby high-voltage motors or generators. This ensures that the vibration waveforms remain deterministic and clean, providing reliable data for the 3500 Monitoring System.

FAQs

• Is this 330101-00-40-05-02-00 probe a brand-new unit?

  Yes. We supply this probe exclusively as 100% Brand New original factory stock. Each unit arrives in its original Bently Nevada protective packaging with all factory inspection markings to guarantee authenticity and performance.

• Which extension cable should I pair with this 0.5-meter probe?

  To achieve a standard 5.0-meter system length, you must pair this 0.5-meter probe with a 4.5-meter 3300 XL extension cable. For a 9.0-meter system, pair it with an 8.5-meter extension cable. Ensure the total electrical length matches the calibration of your Proximitor sensor.

• How do I set the correct mechanical gap during installation?

  Adjust the 3/8-24 UNF threading while monitoring the DC Gap voltage at the Proximitor output. For a standard system, a voltage reading of approximately -10.0 VDC indicates the center of the linear range.

• Can this probe operate in high-temperature oil environments?

  The 3300 XL 8mm probe utilizes PPS and stainless steel materials rated for continuous operation up to +177°C. It functions reliably even when submerged or splashed by hot lubricating oils within turbine bearing pedestals.
