Bently Nevada 330101-00-48-10-02-00 3300 XL 8 mm Proximity Probe

Description

High-performance industrial machinery protection and condition monitoring require stable, highly accurate physical displacement data, which is provided by the Bently Nevada 330101-00-48-10-02-00 proximity sensor. Part of the industry-proven 3300 XL 8 mm series, this eddy current probe converts dynamic distance measurements into reliable electrical signals, allowing operators to monitor critical parameters such as shaft vibration, axial position, and oil film thickness in rotating machinery.

This specific transducer configuration features a 3/8-24 UNF thread design without protective armor, allowing direct mounting in standard machine cases. It is engineered with a 0.0-inch unthreaded length, a 4.8-inch overall case length, and a 1.0-meter (3.3 feet) system cable. Connection to the extension cable is facilitated via a robust miniature coaxial ClickLoc connector, designed to prevent loose connections in high-vibration environments.

Features

• Eddy current sensor technology for non-contact static and dynamic displacement measurements.
• Corrosion-resistant 3/8-24 UNF threaded stainless steel case without protective armor.
• Miniature coaxial ClickLoc connector ensures a secure, low-impedance connection with standard coaxial cabling.
• Fully compatible with Bently Nevada 3300 XL proximity transducer systems and diagnostic monitors.
• High-stability tip construction ensures reliable performance under fluctuating industrial temperatures.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• High-speed centrifugal compressor vibration diagnostics.
• Hydroelectric generator shaft alignment.
• Critical process pumps, industrial fans, and gearboxes.

Technical Specifications

Installation Guidelines

• Gap Adjustment: Set the nominal physical gap between the probe tip and target using a calibrated digital voltmeter to establish the target DC bias voltage (typically -10 VDC).
• Mounting Torque: Do not exceed the maximum torque specification for 3/8-24 UNF threads to prevent damaging the sensor housing.
• Cable Protection: Route the coaxial cable away from high-voltage AC cables and use dedicated conduits to minimize electromagnetic interference.
