Description

Technical Overview

The Bently Nevada 21000-33-05-00-035-03-02 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 sealing for integrated proximity probes—critical for accurate shaft vibration, axial position, and speed measurements in rotating equipment such as turbines, compressors, motors, and generators. Its robust construction supports long-term reliability under high-vibration, high-temperature, and chemically aggressive operating conditions commonly found in power generation, oil & gas, and heavy manufacturing facilities.

Engineered to meet stringent API 670 (4th Edition) and ISO 10816 compliance requirements, the 21000-33-05-00-035-03-02 housing features a corrosion-resistant stainless steel body with integrated O-ring seals and a hermetically sealed cable exit port. The design facilitates repeatable probe tip positioning and minimizes signal drift caused by thermal expansion or mechanical stress—ensuring measurement stability across wide ambient temperature ranges (–40 °C to +125 °C). Compatible exclusively with Bently Nevada 3300 XL 5 mm and 8 mm proximity probes, it integrates seamlessly with 3500/3300 series monitoring systems, enabling real-time data acquisition for predictive maintenance and asset integrity programs.

Key Features

• Precision-Machined Stainless Steel Housing: Provides superior mechanical rigidity, EMI/RFI shielding, and resistance to corrosion, moisture, and hydrocarbon exposure.
• API 670-Compliant Design: Meets critical machinery protection standards for vibration and position monitoring in safety-critical rotating equipment.
• Integrated Sealing System: Dual O-ring seals and strain-relieved cable gland ensure IP67-rated ingress protection for harsh industrial environments.
• Probe Alignment Stability: Precision bore tolerances (±0.005 mm) maintain consistent probe-to-target gap, minimizing calibration drift and measurement uncertainty.
• Plug-and-Play Integration: Designed for direct compatibility with Bently Nevada 3300 XL probe extensions and 3500 rack-based monitoring systems.
