Description

Technical Overview

The Bently Nevada 21000-16-05-00-066-04-02 Proximity Probe Housing Assembly is a precision-engineered, factory-assembled component designed for seamless integration with Bently Nevada 3300 XL and 3500 series proximity probe systems. Engineered to meet stringent API 670 (4th Edition) and ISO 10816 vibration monitoring standards, this housing assembly ensures optimal mechanical stability, thermal consistency, and electromagnetic interference (EMI) immunity—critical for reliable shaft displacement, vibration, and position measurements in mission-critical rotating machinery.

Manufactured by Baker Hughes (formerly Bently Nevada), the 21000-16-05-00-066-04-02 features a robust stainless steel (316 SS) body with integrated O-ring sealing and a precisely machined probe mounting interface. It accommodates standard 5 mm or 8 mm diameter probes (e.g., 330104-00-05-05-02-00 or 330180-05-05-05-02-00) and is optimized for high-temperature, high-vibration environments common in gas turbines, steam turbines, compressors, and large motors.

Key Features

• Precision-Machined Stainless Steel Housing: 316 stainless steel construction for superior corrosion resistance, mechanical strength, and thermal stability up to 120°C (248°F).
• Integrated Sealing System: Dual O-ring design (Viton® elastomer) ensures IP67-rated environmental protection against dust, moisture, and oil ingress.
• EMI-Shielded Design: Fully shielded coaxial connection path minimizes electrical noise—critical for accurate high-frequency vibration data acquisition.
• Factory-Calibrated Alignment: Pre-assembled and tested to ensure concentricity and axial alignment within ±0.025 mm tolerance—reducing field commissioning time and measurement drift.
• Standardized Mounting Interface: Compatible with industry-standard 1/4″-28 UNF threaded probe mounts and 3300/3500 system extension cables (e.g., 330130-05-00-00).
• API 670 Compliant: Meets requirements for proximity transducer housings used in machinery protection systems (MPS), including mechanical integrity, labeling, and traceability.
