Bently Nevada 21000-16-05-00-078-04-02 Proximity Probe Housing Assembly

Description

This 21000-16-05-00-078-04-02 proximity probe housing assembly provides a robust mounting and protection interface for 3300 XL 8 mm proximity transducers in industrial machinery monitoring applications. Designed for environments requiring standard mounting configurations, this assembly ensures the precise positioning of the proximity probe relative to the target shaft, adhering to industry standards for vibration and position monitoring.

The configuration includes an integrated 0.5 m probe cable (Option B: 05), no standoff adapter (Option C: 00), a probe penetration length of 7.8 in (Option D: 078), a single 3/4-14 NPT plug (Option E: 04) for conduit sealing, and a 3/4-14 NPT mounting thread (Option F: 02). The aluminum body construction, paired with a stainless steel sleeve, ensures durability in demanding industrial service, including power generation, petrochemical, and rotating machinery installations.

Installation Guidelines

• Ensure the probe lead is longer than the assembly sleeve length to allow for proper routing.
• For probe penetration lengths exceeding 300 mm (12 in), install additional sleeve support to minimize vibration-induced resonance.
• Install the 3/4-14 NPT mounting thread according to torque specifications for the machine case.
• Verify probe gap settings post-installation to match system requirements for the 3300 XL 8 mm probe.

Compliance and Certifications

• RoHS Directive 2011/65/EU
