Parameter Analysis

Each option block in the 31000-30-05-40-140-03-02 part number defines one element of the hardware configuration, from mechanical dimensions to connector style and approval suffix. The probe Option specifies with Connector : 30=30 3300 XL 8 mm probe, with connector protector, multiple approvals. The probe cable length Option specifies 05 = 0.5 m (20 in). The standoff adapter Option specifies 40 = 4 in. The unit is rated for operation from -51°C to +105°C (-60°F to +221°F).

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

This housing assembly protects the proximity probe where it passes through the machine casing on turbines, compressors, and pumps. It is well suited to wash-down areas, outdoor installations, and hazardous locations where the probe needs mechanical and environmental protection.

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 3300 XL 8 mm 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 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 -51°C to +105°C (-60°F to +221°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 -51°C to +105°C (-60°F to +221°F), covering the temperature extremes typical of turbomachinery installations.

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.
