Bently Nevada 21000-16-05-00-043-03-02 Proximity Probe Housing Assembly

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.

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.
