Parameter Analysis

Configuration of the 21128-14-02 is carried entirely in its part number, which makes the full string the reference point for spare parts planning and system design. The tall cap Option specifies is required if the customer wants to install a. The velomitor ct in a housing. the tall cap Option specifies is also required. The mounting thread and cap Option specifies 14= 1/2-in 14 BSP (G 1/2-in) with tall cap. The unit is rated for operation from -29°C to +121°C (-20 °F to +250°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

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 -29°C to +121°C (-20 °F to +250°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 21128-14-02, contact [email protected].

Frequently Asked Questions

What is the operating temperature range?

The unit is rated from -29°C to +121°C (-20 °F to +250°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.
