Description

Safe and reliable containment of proximity transducers is achieved using the 21000-28-05-00-073-04-02 housing assembly, engineered by Bently Nevada for hazardous and demanding industrial environments. This system acts as a protective conduit and enclosure, enabling the installation of proximity probes directly through machinery casings while maintaining seal integrity and environmental shielding.

This specific configuration integrates a 3300 XL 8 mm proximity probe featuring multiple international hazardous area approvals. With an overall probe penetration depth of 7.3 inches, the assembly installs directly into machine housings via 3/4-14 NPT threads. The external mechanical layout is constructed with a rugged aluminum body paired with a durable 304 stainless steel sleeve to deliver superior defense against corrosive and high-vibration operating conditions.

Note: This component configuration has a direct transition path to updated equivalents, such as the 21000-16-05-00-073-04-02 housing assembly. It remains a key maintenance and replacement part for existing plant instrumentation layouts.

Features

Robust Protection: Rugged aluminum body construction combined with a 304 stainless steel sleeve resists physical impacts and corrosive atmospheric conditions.
Pre-Configured Transducer: Includes a factory-installed 3300 XL 8 mm proximity probe with certified hazardous area approvals.
Precise Penetration: 7.3-inch penetration depth accommodates complex casing geometries without requiring a standoff adapter.
Secure Industrial Sealing: Integrated 3/4-14 NPT plug and thread dimensions ensure high-integrity seals at the mounting interface.

Applications

Steam and gas turbine bearing housing instrumentation
Centrifugal compressor and pump shaft vibration monitoring
Industrial gearbox oil-film bearing monitoring
Power generation and petrochemical heavy machinery monitoring

Installation Guidelines

Verify that the machinery casing thread profile matches the 3/4-14 NPT mounting thread option before insertion.
Apply high-quality thread sealant to NPT threads to prevent environmental moisture or process oil leakage.
Ensure proper clearance for the 0.5-meter probe cable during threading to prevent rotational tension or cable twisting.
Ground the aluminum housing assembly according to local industrial explosion-proof electrical safety standards.
