Description

Technical Overview

The Bently Nevada 31000-30-05-40-14-03-02 Proximity Probe Housing Assembly is a precision-engineered component designed for mission-critical shaft vibration and position monitoring in industrial rotating machinery. As part of the industry-standard 3300 XL series ecosystem, this housing assembly ensures optimal mechanical integration, thermal stability, and electromagnetic interference (EMI) shielding for high-fidelity signal integrity. It is engineered to securely mount standard 3300 XL proximity probes while maintaining precise probe-to-target alignment—critical for accurate displacement measurements in gas turbines, steam turbines, compressors, and large electric motors.

Constructed from corrosion-resistant stainless steel with a robust, hermetically sealed design, the 31000-30-05-40-14-03-02 withstands harsh operating environments—including high humidity, oil mist, extreme temperature fluctuations, and aggressive chemical exposure common in power generation, oil & gas, and marine propulsion applications. Its threaded mounting interface (M18 × 1.5) and integrated O-ring seal comply with API 670 (4th Edition) and ISO 10816 standards, ensuring seamless compatibility with existing Bently Nevada monitoring systems and facilitating straightforward retrofits or new installations.

Key Features

• Precision-Machined Stainless Steel Housing: Provides superior durability, EMI/RFI shielding, and long-term dimensional stability under thermal cycling.
• API 670–Compliant Design: Ensures adherence to industry requirements for machinery protection system (MPS) reliability and measurement repeatability.
