Description

The 21000-16-05-00-043-03-02 is a Bently Nevada proximity probe housing assembly designed for 3300 XL 8 mm probe configurations. This unit provides a protective environment for the transducer and facilitates accurate, reliable shaft vibration and position monitoring in industrial machinery applications. This specific configuration features a 0.5 meter probe cable, no standoff adapter, and a probe penetration depth of 4.3 inches. It is equipped with a cable seal grip fitting and utilizes a 3/4-14 NPT mounting thread for secure installation into the machine case.

The 21000 series housing is constructed with an aluminum body and a 304 stainless steel sleeve to ensure mechanical integrity in harsh operating conditions. It adheres to the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings, supporting critical asset protection and machinery diagnostic programs. This assembly is designed for reliable performance across a broad temperature range, compatible with 3300 XL 8 mm transducer systems.

Features

  • Compatible with 3300 XL 8 mm proximity probe systems
  • Configured with 0.5 m (20 in) probe cable length
  • Includes one cable seal grip fitting with integrated grommets (0.125 to 0.375 inch cable capacity)
  • 3/4-14 NPT mounting thread configuration
  • Aluminum body construction with 304 stainless steel sleeve
  • 4.3 inch (109.2 mm) probe penetration depth
  • Meets API 670 standards for externally mounted proximity probe housings

Applications

  • Rotating machinery shaft vibration monitoring
  • Axial position and thrust measurements
  • Fluid film bearing protection

Installation Guidelines

Ensure the probe penetration length is correctly set during installation to match the machine requirements. For penetration lengths between 1.0 and 2.0 inches, it may be necessary to counterbore the machine case to reduce side-view or rear-view effects. Ensure the 3/4-14 NPT threads are properly engaged and sealed. If the total probe penetration exceeds 300 mm (12 in), additional sleeve support must be added near the probe tip to prevent resonance.

FAQ

What does the 16 code represent in this 21000 housing assembly?

The 16 code signifies that this housing assembly is configured for the 3300 XL 8 mm proximity probe series.

Can this housing be used for explosion-proof applications?

While explosion-proof fittings are available for this series, only CA versions of the housing are certified by CSA as explosion-proof for North American end users. Standard 21000 housings are designed for general purpose and hazardous area environments as specified in the Approvals Quick Reference Guide.

Is a standoff adapter included with this part number?

No, the 00 code in the C segment indicates that no standoff adapter is included with this specific configuration.

What is the probe penetration depth for this unit?

This unit is configured with a 4.3 inch probe penetration depth (Option 043).
