Product Overview

The Bently Nevada 31000-28-10-00-020-03-02 is an all-in-one PROXPAC XL transducer assembly that revolutionizes traditional proximity probe installations. This specialized housing integrates the proximity probe and the Proximitor sensor into a single, compact unit, effectively eliminating the need for external extension cables and separate sensor enclosures. Constructed from glass-reinforced, conductive Polyphenylene Sulfide (PPS), the housing offers superior chemical resistance and electrostatic dissipation. This "cable-less" internal design simplifies the signal path, reducing potential failure points while providing the external adjustability required for precise gap setting on rotating machinery shafts.

Industrial Applications

The 31000-28-10-00-020-03-02 PROXPAC XL is primarily utilized in the power generation and hydrocarbon processing industries where "casing-mount" accessibility is essential. It is the preferred solution for:

• Steam and Gas Turbines Monitoring radial vibration and axial thrust where the sensor must be protected from high-temperature environments.

• Centrifugal Compressors Providing a self-contained vibration monitoring point that simplifies field wiring to the central control room.

• Remote Pumping Stations Reducing system complexity by housing the electronics directly at the measurement point, ideal for distributed monitoring architectures.

• Corrosive Environments Utilizing the PPS housing to prevent the oxidation and degradation common with traditional aluminum or steel enclosures in salt-spray or chemical-heavy zones.

By integrating the Proximitor sensor into the housing cap, this assembly allows for shorter field wiring runs and significantly reduces the labor required for installation and calibration. It provides a robust, reliable data source for any Turbine Supervisory Instrumentation (TSI) system or 3500 Series machinery protection rack.
