Bently Nevada 330905-00-25-05-02-05 3300 NSv Proximity Probe

Description

The 330905-00-25-05-02-05 3300 NSv proximity probe is a 5 mm eddy-current transducer designed for the Bently Nevada 3300 XL NSv proximity transducer system. This specific configuration features a 0.0 in unthreaded length (Option 00), 2.5 in case length (Option 25), 0.5 m total system length (Option 05), standard miniature ClickLoc connector (Option 02), and is rated for CSA, ATEX, and IECEx hazardous area environments (Option 05).

Designed for applications where standard 8 mm probes are physically too large, the NSv probe provides the necessary measurement range for small-bore machinery and high-speed equipment with limited target areas. It connects to the 330980 Proximitor sensor and 330930 extension cable to form a complete monitoring system for shaft vibration and axial position measurements in turbines, compressors, and pumps.

Features

• 5 mm probe tip diameter suited for small-bore applications and tight mounting constraints
• Miniature ClickLoc connector interface ensures secure coupling with 330930 extension cables
• Option 05 configuration supports hazardous area operation with CSA, ATEX, and IECEx certifications
• 2.5 in case length with 0.0 in unthreaded length for standardized mechanical mounting
• Linear measurement range compatible with 330980 NSv Proximitor sensors

Applications

• Aeroderivative gas and steam turbines
• Small-bore centrifugal compressors
• High-speed motors and gearboxes
• Rotating machinery with limited target geometry
• General purpose shaft vibration and axial position monitoring

Installation Guidelines

Ensure the probe is mounted securely in a standard 3300 NSv probe holder. Maintain proper probe-to-target gap spacing as specified in the system datasheet to prevent clipping the signal. Cable routing should avoid high-temperature zones and avoid sharp bends that could stress the ClickLoc connector interface. Always verify that the Proximitor sensor is calibrated to the specific probe and extension cable length before final commissioning.

Compliance and Certifications

This unit complies with CSA, ATEX, and IECEx standards for operation in hazardous environments when installed according to local regulations and the control drawing.
