Description

Technical Overview

The Bently Nevada 21000-28-05-15-50-03-02 Proximity Probe Housing Assembly is a precision-engineered component designed for demanding industrial condition monitoring applications. As part of the industry-standard 3300 XL series ecosystem, this housing assembly ensures optimal mechanical integration, electromagnetic shielding, and thermal stability for high-reliability shaft vibration and position measurements in rotating machinery—including turbines, compressors, motors, and generators. Its robust construction supports consistent probe alignment and repeatable gap voltage output, critical for accurate machine health assessment in predictive maintenance programs.

Engineered to meet stringent API 670 (4th Edition) and ISO 10816 standards, the 21000-28-05-15-50-03-02 housing features a corrosion-resistant stainless steel body with integrated strain relief and hermetic sealing—enabling reliable operation in harsh environments characterized by high humidity, oil mist, extreme temperatures (–30°C to +125°C), and aggressive chemical exposure. The housing’s optimized internal geometry minimizes eddy current interference and signal attenuation, preserving the integrity of the high-frequency AC signals transmitted between the proximity probe and the monitor system. Compatibility with standard 3300 XL extension cables and monitors ensures seamless integration into existing Bently Nevada asset protection systems without requiring firmware updates or configuration changes.
