Description

Technical Overview

The Bently Nevada 21000-34-10-20-058-04-02 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 stability, thermal consistency, and electromagnetic shielding—critical factors in maintaining probe calibration integrity and signal fidelity across extended operational lifecycles. Its robust stainless steel construction and hermetically sealed design deliver exceptional resistance to oil, coolant, dust, and vibration, making it ideal for deployment in harsh environments such as power generation turbines, compressors, pumps, and large rotating equipment in oil & gas, petrochemical, and manufacturing facilities.

Engineered to interface seamlessly with Bently Nevada 3300 XL proximity probes (e.g., 330104-00-05-05-02-00), the 21000-34-10-20-058-04-02 housing provides precise axial alignment and repeatable mounting geometry. The integrated threaded body (M10 × 1.0 mm) and standardized 58 mm overall length ensure compatibility with existing sensor mounting configurations and OEM retrofit programs. Its low thermal expansion coefficient minimizes drift during wide ambient temperature swings (–30°C to +120°C), supporting long-term measurement reliability without recalibration. This housing assembly is certified to meet stringent IEC 61508 SIL 2 functional safety requirements when used within approved Bently Nevada system architectures.

Key Features

• Precision-Machined Stainless Steel Housing: Ensures corrosion resistance, mechanical rigidity, and long-term dimensional stability in aggressive industrial environments.
• EMI/RFI Shielding Compliance: Integral conductive gasketing and grounded metal enclosure maintain signal integrity and suppress electromagnetic interference per IEC 61000-4-3 standards.
• Interchangeable & Retrofit-Ready Design: Direct replacement for legacy 3300 series installations; compatible with standard 3300 XL extension cables and monitor interfaces.
• Hermetic Sealing (IP67 Rated): Protects internal probe connections from moisture, particulates, and chemical exposure—validated per IEC 60529.
• Thermally Stable Mounting Platform: Minimizes thermal-induced probe drift through matched CTE (Coefficient of Thermal Expansion) between housing and probe body.
