Bently Nevada 21000-16-05-00-055-03-02 Proximity Probe Housing Assembly

Description

The 21000-16-05-00-055-03-02 is a Bently Nevada aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This configuration includes a 3300 XL 8 mm proximity probe (Option 16) with a 0.5 m (20 in) probe cable length (Option 05). It is engineered to provide a robust, protective environment for the probe, meeting API 670 standards for machinery vibration and position monitoring.

This assembly features a 0.0 in standoff adapter (Option 00) and a 5.5 in probe penetration length (Option 055). The housing is equipped with a cable seal grip fitting (Option 03) and utilizes 3/4-14 NPT mounting threads (Option 02). The 21000 series is constructed from durable aluminum, offering a cost-effective solution for industrial machinery protection in non-hazardous or appropriately approved installations.

Installation Guidelines

Ensure the housing is mounted securely to the machine case. For probe penetration lengths greater than 300 mm (12 in), auxiliary sleeve support is required to minimize vibration-induced resonance. Ensure all conduit fittings are tightened to maintain the enclosure integrity. When installing the probe into the housing, ensure the correct gap is maintained per the specific 3300 XL probe system documentation.

Compliance and Certifications

The 21000 series housing assemblies are compliant with RoHS Directive 2011/65/EU and the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings.
