Description

The 21000-28-05-00-092-03-02 is a Bently Nevada proximity probe housing assembly designed for industrial machinery vibration monitoring applications. This configuration features a 3300 XL 8 mm proximity probe (Option 28) with selectable hazardous area approvals and a 0.5 m (20 in) integral probe cable (Option 05). The housing is configured without a standoff adapter (Option 00) and includes a probe penetration length defined by the 092 option code. It is equipped with a cable seal grip fitting (Option 03) and 3/4-14 NPT mounting threads (Option 02).

This housing assembly provides robust mechanical protection for the probe and cable in demanding environments, ensuring consistent signal integrity for axial position and vibration measurements. It is engineered for compatibility with 3300 XL transducer systems, facilitating reliable shaft monitoring in diverse rotating machinery such as turbines, compressors, and pumps.

Features

  • 3300 XL 8 mm Probe (Option 28): Includes selectable hazardous area approvals for safe operation in explosive atmospheres.
  • 0.5 m (20 in) Probe Cable (Option 05): Integrated cable length for standard installation distances.
  • No Standoff Adapter (Option 00): Compact assembly without additional standoff extension.
  • Cable Seal Grip (Option 03): Includes grommets for various cable sizes (1/8 to 3/16 inches, 1/4 to 5/16 inches, 5/16 to 3/8 inches).
  • 3/4-14 NPT Mounting Thread (Option 02): Standard industrial thread type for secure machine case attachment.

Applications

  • Turbine-generator sets
  • Centrifugal and axial compressors
  • Large industrial fans and blowers
  • Reciprocating machinery
  • Critical pump monitoring

Installation Guidelines

Ensure the probe is installed with the correct gap as specified by the transducer system documentation. When using the cable seal grip (Option 03), select the appropriate grommet size to ensure a proper moisture and dust seal. If the total probe penetration length exceeds 300 mm (12 in), additional sleeve support is required to prevent vibration-induced resonance. Always verify machine case conditions for counter-boring requirements if probe penetration is less than 1.0 inch.

FAQ

What does the 28 option code indicate for this 21000 assembly?

The 28 option code specifies a 3300 XL 8 mm proximity probe with selectable hazardous area approvals.

Does this housing come with a standoff adapter?

No, the 00 option code for the standoff adapter indicates that no standoff adapter is included with this configuration.

What size cable does the 03 fitting support?

The 03 fitting (cable seal grip) includes grommets for cable sizes 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches.

Is this housing assembly explosion-proof?

Standard 21000 housings require specific installation and CA certification (e.g., CA21000) to meet explosion-proof ratings for North America. Please verify your site requirements and local certifications.

What is the material composition of the 21000 body?

The 21000 series housing body is constructed from aluminum with a 304 stainless steel sleeve.
