Description

Technical Overview

The Bently Nevada 21000-28-05-00-092-03-02 Proximity Probe Housing Assembly is a precision-engineered component designed for demanding industrial condition monitoring and machinery protection applications. As part of the industry-standard 3300 XL series ecosystem, this housing assembly ensures optimal mechanical alignment, electromagnetic shielding, and environmental protection for high-reliability eddy-current proximity probes used in turbomachinery, compressors, motors, and generators. Its robust construction supports consistent probe gap stability under thermal cycling, vibration, and pressure fluctuations—critical for accurate shaft displacement, vibration, and position measurements in critical rotating equipment.

Engineered to meet stringent API 670 (4th Edition) and ISO 10816 standards, the 21000-28-05-00-092-03-02 integrates seamlessly with Bently Nevada’s 3300/5000-series monitors and data acquisition systems. The housing features a corrosion-resistant stainless steel body with precision-machined threads and sealing surfaces, enabling reliable performance in harsh environments—including high-humidity, oil-laden, or chemically aggressive settings common in power generation, oil & gas, and marine propulsion facilities. Its modular design simplifies installation, calibration, and field maintenance while minimizing downtime during sensor replacement or system upgrades.

Key Features

• Precision-Machined Stainless Steel Housing: Ensures long-term dimensional stability, EMI/RFI shielding, and resistance to corrosion, abrasion, and thermal expansion.
• Optimized Electromagnetic Compatibility (EMC): Maintains signal integrity by minimizing external noise coupling—essential for high-fidelity vibration and displacement data acquisition.
• API 670-Compliant Design: Supports machinery protection system (MPS) requirements for trip-grade reliability, including redundant mounting options and traceable calibration interfaces.
• Interchangeable with 3300 XL Series Probes: Enables plug-and-play integration with standard 5 mm and 8 mm diameter proximity sensors, reducing spares inventory and commissioning time.
• IP67-Rated Sealing: Provides ingress protection against dust and temporary water immersion, ensuring operational continuity in challenging plant environments.
