Bently Nevada 21000-16-05-00-076-04-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-00-076-04-02 is an aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This configuration features a 3300 XL 8 mm proximity probe (Option 16) with a 0.5 m cable length (Option 05). The assembly is configured with no standoff adapter (Option 00) and a probe penetration depth of 7.6 inches (Option 076). It includes one 3/4-14 NPT plug (Option 04) and utilizes a 3/4-14 NPT mounting thread (Option 02).

Engineered for use in harsh industrial environments, these housings protect the probe and cable termination while providing a secure, vibration-resistant mount for machine case monitoring. The 21000 series housing provides a robust aluminum enclosure compliant with API 670 standards for externally mounted proximity probe housings, ensuring compatibility with standard machinery protection systems in power generation, petrochemical, and oil and gas facilities.

Installation Guidelines

Ensure the housing is mounted securely to the machine case using the 3/4-14 NPT thread. When installing, verify that the probe penetration depth is adjusted correctly for the specific machine application. If the probe penetration length (C + D) exceeds 300 mm (12 in), install additional sleeve support to prevent resonance. Ensure all conduit fittings are properly sealed to maintain the environmental integrity of the enclosure. For hazardous area installations, confirm that all explosion-proof fittings are installed according to local regulatory and safety standards.
