Product Description

Overview

The Bently Nevada 128229-01 is an external housing assembly for proximity probes, designed for 3300 and 7200 Series proximity transducer systems. It provides a protective mounting platform for proximity probes, allowing secure installation and adjustment without requiring disassembly of the monitored machinery. This assembly ensures probe integrity and reliability in harsh industrial environments.

Key Features

Environmental Protection

• Sealed Entry: Oil-tight design prevents ingress of oil, moisture, or contaminants into the machine casing.

• Durable Construction: Manufactured from high-grade stainless steel or aluminum, resistant to corrosion and industrial chemicals.

• Hazardous Area Compatibility: Suitable for use in Class I, Div 1/2 and ATEX/IECEx rated environments when paired with the appropriate probe and barrier system.

Mechanical Precision and Adjustability

• Gap Calibration: Supports precise adjustment of the probe tip relative to the shaft for accurate vibration and thrust measurements.

• External Mounting: Facilitates probe alignment and gap measurement without removing major machine covers, simplifying maintenance.

Physical Specifications

Applications

• Radial shaft vibration monitoring in turbines, compressors, and pumps

• Thrust (axial) position sensing to prevent metal-to-metal contact

• Keyphasor® pulse generation for phase and speed tracking in rotating machinery

Note: Ensure correct modification or option code is selected when ordering, as thread type and housing length vary depending on the specific machine.
