Bently Nevada 21000-16-05-15-072-03-02 Proof Housing

Product Overview

The Bently Nevada 21000-16-05-15-072-03-02 is a high-integrity Proximity Probe Housing Assembly designed for external mounting on critical industrial machinery. This assembly provides a ruggedized, explosion-proof enclosure for 3300 XL 8mm proximity probes, ensuring reliable shaft vibration and position monitoring in accordance with API 670 standards.

This model features a 7.2-inch (183 mm) probe penetration depth and a 1.5-inch standoff adapter, optimized for medium-depth machine casings. The assembly is constructed with an aluminum body and a 304 stainless steel sleeve, resulting in a typical weight of 1.1 kg (2.4 lb) without fittings, striking an ideal balance between structural durability and ease of installation.

Technical Configuration

Key Performance Features

• Global Safety Compliance: Certified by CSA for explosion-proof applications in Class I Div 1/2 and Class II environments, rated as a Type 4 enclosure.
• Precise Adjustment: The penetration depth (Option D) offers an adjustment range of ±13 mm (±0.5 in), allowing for post-installation fine-tuning of the probe gap.
• Environmental Resilience: Designed for extreme ambient temperatures ranging from -50 °C to +80 °C (T4 rating), ideal for harsh petrochemical and power generation sites.
• Comprehensive Fitting Set: Includes a 3/4-14 NPT plug, a 1/2-14 NPT reducer, and a versatile cable seal grip compatible with cable sizes from 1/8" to 3/8".

Installation Guidance

The 21000-16-05-15-072-03-02 is engineered for ease of maintenance with a screw-in dome cover and integrated O-ring seals. For high-vibration applications, the 304 stainless steel sleeve provides the necessary rigidity to maintain probe alignment. This unit is fully RoHS compliant and meets the technical requirements of API 670 for externally mounted proximity probe housings.

Technical FAQs
