Bently Nevada 21000-16-10-00-053-03-02 Proximity Probe Housing Assemblies

Description

The 21000-16-10-00-053-03-02 is a Bently Nevada 21000 series proximity probe housing assembly, designed for the secure installation and protection of 3300 XL 8 mm proximity transducer systems in industrial machinery. This specific configuration features a 3300 XL 8 mm probe (Option 16), a 1.0 m probe cable length (Option 10), no standoff adapter (Option 00), a probe penetration of 5.3 in (Option 053), and a cable seal grip fitting (Option 03) with 3/4-14 NPT mounting threads (Option 02).

The 21000 housing assembly provides an aluminum body with a 304 stainless steel sleeve to meet API 670 standards for externally mounted proximity probes. It ensures that the transducer system is correctly positioned and protected from environmental factors in rotating machinery, including pumps, compressors, and turbines. The housing includes a cable seal grip fitting to maintain protection ratings at the conduit entry point.

Features

• 3300 XL 8 mm probe (Option 16) integration for precision shaft vibration and axial position measurement.
• 1.0 m probe cable (Option 10) integrated within the housing assembly.
• Standoff adapter omitted (Option 00) for direct mount configurations.
• 5.3 in probe penetration (Option 053) for correct probe gap and target alignment.
• Cable seal grip fitting (Option 03) includes grommets for cable sizes 1/8 to 3/8 inches.
• 3/4-14 NPT mounting thread (Option 02) providing mechanical stability to the machine case.
• Aluminum body construction with 304 stainless steel sleeve for durability.

Applications

• Critical rotating machinery protection for turbines, compressors, and pumps.
• Shaft vibration and axial (thrust) position monitoring.
• Applications requiring API 670 compliant, externally mounted proximity probe protection.
• Hazardous area environments where NPT conduit connections are required (refer to system-wide approvals).

Installation Guidelines

Ensure the probe penetration length (C + D) is calculated correctly for your specific machine case to avoid side-view or rear-view effects. For penetration lengths between 1.0 and 2.0 inches, counter-boring the machine case may be necessary. For probe penetration lengths exceeding 300 mm (12 in), additional sleeve support must be installed near the probe to prevent resonance. Torque the housing into the machine case according to standard industrial practices for 3/4-14 NPT threads.

Compliance and Certifications

RoHS: European Community Directive 2011/65/EU. For hazardous area applications, ensure the total system (probe, extension cable, and Proximitor sensor) is installed per the applicable drawing provided in the transducer system user guide.
