Parameter Analysis

Configuration of the 330903-00-03-50-02-00 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 -00- 00 mm. The overall case length Option specifies -03-30 mm. The total length Option specifies 50 5.0 meters (16.4 feet). The unit is rated for operation from -52°C to +177°C (-62°F to +351°F).

Because cable, probe, and Proximitor are calibrated as a system, keeping the same part numbers across the loop preserves scale factor accuracy and simplifies replacement during outages.

Application Scenarios

This extension cable connects the proximity probe to its Proximitor on turbines, compressors, pumps, and other rotating equipment, routing the measurement signal from the machine casing to the electronics location while preserving signal integrity over the full system length.

Installation Guide

Plan the run so that probe integral lead plus extension cable matches the intended total system length, route the cable away from pinch points and hot surfaces, and seat the connectors fully. Verify the loop after installation by confirming the probe gap voltage at the monitor.

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 cable jacket and connectors during outages for cuts, moisture ingress, or loosened couplings, and confirm the run remains clear of abrasive surfaces. Keep the unit within its -52°C to +177°C (-62°F to +351°F) operating envelope in service and storage.

Procurement Advice

This unit is supplied new & original in factory packing with 12 months factory warranty. 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 connector or interface does it use?

It uses miniature coaxial ClickLoc connector, 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.

How do I confirm the right part number?

Check every option digit against the machine bill of materials, then contact [email protected] with the full string; the TenBN team will confirm fit, stock, and documentation.
