Product Overview

The Bently Nevada 21000-16-10-15-034-03-02 is a professional-grade Proximity Probe Housing Assembly designed for the external mounting of 3300 XL 8mm probes. This explosion-proof system is a critical component for machinery protection, providing a secure environment for transducers in high-vibration applications. Fully compliant with API 670 standards, it ensures precise gap measurement for rotating equipment.

Constructed with a durable aluminum body and a 304 stainless steel sleeve, this assembly features a weight of 1.1 kg. Its design supports 3.4-inch (86.4 mm) probe penetration and is CSA Type 4 certified, making it a reliable choice for the demanding safety requirements of the oil, gas, and power generation industries.

Technical Configuration

Installation & Mechanical Features

• Field Adjustability: The probe penetration depth is adjustable by ±0.5 inches (13 mm), allowing for perfect transducer gapping during site setup.
• Explosion-Proof Security: Rated for Class 1 Div 1 & 2 (Groups C, D), the housing provides a moisture-proof and gas-tight seal at conduit entries.
• Thermal Tolerance: Designed for extreme plant conditions with a rated temperature range of -50°C to +80°C.
• Serviceability: The screw-in dome cover allows for easy access to the reverse-mount probe without removing the entire housing assembly.

Engineering Advantages

The Bently Nevada 21000 series is the industry benchmark for externally mounted proximity probes. By utilizing a corrosion-resistant stainless steel sleeve and a lightweight aluminum body, it meets rigorous mechanical safety standards. Its 1.5-inch standoff adapter is ideal for equipment with thick insulation or external cooling jackets, providing necessary clearance while maintaining signal integrity.
