Parameter Analysis

Configuration of the 330750-80-05 is carried entirely in its part number, which makes the full string the reference point for spare parts planning and system design. The unit is rated for operation from -55°C to +400°C (-67°F to +752°F). Compliance documentation covers multiple Approvals (CSA, ATEX, and IECEx).

The housing assembly seals the probe penetration against wash-down and dust while allowing standard probe maintenance, combining mechanical protection with the electrical performance of the enclosed probe.

Application Scenarios

Installations on rotating machinery that demand sealed probe penetrations rely on this housing to guard against dust, hose-directed water, and mechanical contact while keeping the probe serviceable.

Installation Guide

Confirm every option digit against the machine drawing, mount the housing through its threaded connection, tighten the retaining nut to the documented torque, and keep the sleeve O-rings seated to preserve the environmental seal. Set the probe gap after assembly and verify before start-up.

Compatibility

This component belongs to the Bently Nevada condition monitoring portfolio 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 housing cover, screws, and O-rings at each maintenance opportunity, and confirm the retaining nut torque has not relaxed in service. Keep the unit within its -55°C to +400°C (-67°F to +752°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. For inventory, pricing, and lead time on the 330750-80-05, contact [email protected].

Frequently Asked Questions

What is the operating temperature range?

The unit is rated from -55°C to +400°C (-67°F to +752°F), covering the temperature extremes typical of turbomachinery installations.

What approvals or certifications does it carry?

Compliance documentation covers multiple Approvals (CSA, ATEX, and IECEx). Confirm the approval suffix on your part number before ordering for hazardous-area use.

What connector or interface does it use?

It uses -pin Mil-C-5015 receptacle, hermetically-sealed, 304 stainless steel shell, 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.
