Parameter Analysis

Each option block in the 990-08-70-03-01 part number defines one element of the hardware configuration, from mechanical dimensions to connector style and approval suffix. The full-scale Option specifies 08 0-8 mils pp (0-200 μm pp). The system length Option specifies 70 7.0 meters (23.0 feet). The mounting Option specifies 03 DIN clips and screws. Compliance documentation covers cSA Division 2.

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

Used wherever the proximity measurement loop must bridge the distance between probe and Proximitor, this cable suits junction-box and electronics-room installations on turbomachinery trains.

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.

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. For inventory, pricing, and lead time on the 990-08-70-03-01, contact [email protected].

Frequently Asked Questions

What approvals or certifications does it carry?

Compliance documentation covers cSA Division 2. Confirm the approval suffix on your part number before ordering for hazardous-area use.

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.
