Product Description

Overview

The Bently Nevada 172103-01 is a heavy-duty proximity probe housing engineered for the 3300 XL series. Designed for industrial environments with extreme conditions, it provides a secure mounting point for 8mm and 11mm proximity probes while protecting the sensor from oil, debris, and high-pressure conditions. This assembly ensures accurate shaft displacement and vibration measurements while meeting rigorous safety and explosion-proof standards.

Key Technical Features

Industrial & Hazardous Area Compliance

• Explosion-Proof Design: Certified to ATEX, IECEx, and CSA standards for use in hazardous locations such as oil refineries and chemical plants.

• Flame-Path Containment: Prevents any internal spark from igniting the surrounding atmosphere.

Sealing and Mechanical Protection

• Oil- and Gas-Tight Integrity: High-quality O-rings and seals prevent leaks from bearing housings or crankcases.

• High-Pressure Resilience: Maintains sealing integrity even under elevated machine pressures.

• Rugged Construction: Built from corrosion-resistant 303 or 316 stainless steel, or optional aluminum for offshore and chemical processing environments.

Precision Probe Positioning

• Adjustable Gap: Allows fine-tuning of the probe-to-shaft distance for accurate linear displacement measurement.

• Vibration Resistance: Rigid mechanical design prevents false vibration readings caused by housing movement.

• Locking Mechanisms: Set screws or locknuts secure the probe in place for long-term stability.

Technical Specifications

Typical Applications

• Steam and Gas Turbines: Axial thrust and radial vibration monitoring

• Centrifugal Compressors: Shaft stability and surge protection
