Bently Nevada 330903-00-04-05-02-00 3300 XL NSv Proximity Probe

Description

The 330903-00-04-05-02-00 is a 3300 XL NSv proximity probe designed for precision displacement measurements in machinery with tight installation constraints. This configuration features an M8x1 thread (330903), 0.0 in unthreaded length (Option 00), 0.4 in case length (Option 04), 0.5 m total length (Option 05), and a standard miniature coaxial ClickLoc connector (Option 02) without hazardous area approvals (Option 00).

Engineered for the 3300 XL NSv proximity transducer system, this probe excels in applications where standard probes are unsuitable due to limited target area or restricted space. It is commonly used for radial vibration, axial position, and tachometer measurements on fluid-filmed bearing machines, particularly for small-bore shafts or applications requiring reduced side-view interference.

Features

• M8x1 thread configuration with unarmored design.
• 0.5 meter (20 in) total system length.
• Miniature coaxial ClickLoc connector for reliable signal transmission.
• Designed for use with 3300 XL NSv Proximitor sensors and extension cables.
• Suitable for radial, axial, and tachometer measurements on tight-clearance equipment.
• Optimized for small targets and reduced side-view environments.

Applications

• Radial vibration and position monitoring on small-bore machinery.
• Axial (thrust) position measurement for shafts smaller than 51 mm (2 in).
• High-speed equipment and aeroderivative turbine monitoring.
• Applications with counterbore, side-view, or rearview installation restrictions.
• Tachometer and zero-speed sensing.

Installation Guidelines

Ensure the probe is installed with the correct torque settings; for M8x1 probe cases, the recommended torque is 5.1 N m (45 in lb) with a maximum of 7.3 N m (65 in lb). Use a matching thread fit class for the installation. Ensure that the extension cable and probe length combined equal the Proximitor sensor total length for calibrated operation. Connectors should be kept clean and dry; the use of connector protectors is recommended in environmental conditions where moisture or contaminants may be present.

Compliance and Certifications

This unit is configured with Option 00 (Agency Approval Not Required). For systems requiring hazardous area certifications, ensure the proper approval option (e.g., Option 05) is selected during system design.
