Parameter Analysis

Configuration of the 330908-12-46-05-02-05 is carried entirely in its part number, which makes the full string the reference point for spare parts planning and system design. The unthreaded length Option specifies 12= 1.2 in. The overall case length Option specifies 46=4.6 in. The total length Option specifies 05 0.5 meter (20 in). The unit is rated for operation from -52°C to +177°C (-62°F to +351°F). Compliance documentation covers multiple Approvals.

Probe performance is specified together with the matching extension cable and Proximitor, so replacing the complete loop under consistent part numbers preserves the calibrated scale factor and linearity of the measurement chain.

Application Scenarios

This probe is installed on steam and gas turbines, compressors, pumps, motors, and fans to measure radial and axial shaft vibration, position, and speed. It feeds the associated monitoring rack, giving operators the early warning needed to plan maintenance before a developing fault becomes unplanned downtime.

Installation Guide

Thread the probe into its tapped hole, respect the thread engagement limits of the case, and mate the connector to the matching extension cable. Set the initial gap according to the electrical requirements of the associated Proximitor and verify the gap voltage against system documentation before returning the machine to service.

Compatibility

This component belongs to the 3300 NSv proximity system and is engineered to work with the associated probes, extension cables, Proximitors, and monitoring hardware of the same system. Bently Nevada components sharing the same part number are fully interchangeable, so a stocked spare can be fitted without re-engineering the measurement loop. TenBN can supply the complete chain under consistent part numbers.

Maintenance Advice

Inspect the probe tip, threads, and cable jacket at each outage for wear or damage, and confirm connector seating and torque have not relaxed in service. Keep the unit within its -52°C to +177°C (-62°F to +351°F) operating envelope in service and storage.

Procurement Advice

Confirm the complete part number against your machine’s bill of materials before ordering, since each option digit changes the mechanical or electrical fit. TenBN stocks genuine Bently Nevada components and provides the official service documentation for this model.

Frequently Asked Questions

What is the operating temperature range?

The unit is rated from -52°C to +177°C (-62°F to +351°F), covering the temperature extremes typical of turbomachinery installations.

What approvals or certifications does it carry?

Compliance documentation covers multiple Approvals. Confirm the approval suffix on your part number before ordering for hazardous-area use.

What connector or interface does it use?

It uses miniature coaxial ClickLoc connector, standard cable, matching the standard Bently Nevada measurement chain.

Can this spare be interchanged with existing components?

Bently Nevada components sharing the same part number are fully interchangeable, so this spare can replace an existing unit without recalibrating the loop when the complete part number matches.
