Product Overview

The Bently Nevada 21000-16-05-00-055-03-02 is a comprehensive external mounting solution designed for the 3300 and 3300 XL proximity transducer systems. This housing assembly facilitates the installation of proximity probes through machine casings, providing a protected environment for the sensor while allowing for precise gap adjustment. It is a critical component for Turbine Supervisory Instrumentation (TSI), enabling the monitoring of radial vibration, axial thrust, and phase reference on high-speed rotating assets.

This specific assembly configuration is engineered to withstand harsh industrial atmospheres. It provides an environmental seal for the probe and cable connections, shielding them from contaminants such as oil, moisture, and debris. By utilizing a standoff adapter and a reverse-mount probe design, the 21000-16-05-00-055-03-02 ensures that maintenance personnel can access or replace sensors without a complete machinery teardown.

Configuration and Design Features

The 21000 series housing is modular, with each suffix in the part number 21000-16-05-00-055-03-02 defining a specific hardware variable to match site-specific requirements.

• Probe Integration: The assembly is configured to house a 3300 XL 8mm reverse-mount probe, ensuring high-fidelity signal transduction for vibration analysis.

• Environmental Protection: The unit features a rugged dome cover and O-ring seals that meet industrial ingress protection standards, preventing the entry of process fluids.

• Standoff Adaptability: Included in this configuration is a 5.5-inch standoff adapter, which provides the necessary clearance between the probe housing and the machine casing.

• Conduit Compatibility: Designed with threaded ports to accommodate liquid-tight flexible conduits, ensuring that the transducer cable is fully protected from mechanical damage.

• Adjustable Positioning: The threaded probe sleeve allows for micro-adjustments of the probe-to-target gap, ensuring the sensor remains within its linear electrical range.
