Features:
- PROXPAC XL Proximity Transducer
- Similar to our 31000/32000 Proximity Probe Housing Assemblies
- Made of Polyphenylene Sulfide (PPS), which is an advanced, molded thermoplastic
The assembly offers the same advantages and features as the 31000 and 32000 housings for accessing and externally adjusting proximity probes. However, the housing cover of the PROXPAC XL Assembly also contains its own 3300 XL Proximitor sensor.
This design makes the PROXPAC XL Assembly a completely self-contained proximity probe system, and eliminates the need for an extension cable between the probe and its associated Proximitor sensor. It also eliminates the need for a separate Proximitor housing, as the field wiring connects directly between the monitors and PROXPAC XL Assemblies.
The 330880-28-15-048-00-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The PROXPAC XL proximity sensor assembly works by integrating a proximity probe and the 3300 XL Proximitor sensor into a single housing, forming a complete eddy current displacement measurement system. When the proximity probe approaches a metallic target, it generates a high-frequency electromagnetic field and eddy currents on the target's surface. Changes in the distance between the target and the probe cause changes in the eddy current intensity, thereby altering the impedance of the probe coil. The built-in Proximitor sensor processes and converts this impedance change, outputting a voltage signal proportional to the distance or vibration. This signal is then transmitted directly to the monitoring system via field wiring.
This probe is a standard tool for predictive maintenance and condition monitoring of critical rotating machinery:
Radial Vibration: Measures the lateral movement of the shaft in hydrodynamic bearing machinery such as turbines, compressors, and pumps.
Axial (Thrust) Position: Tracks the longitudinal movement of the rotor to prevent metal-to-metal contact between the rotor and the housing.
Keyphasor® Reference: Provides timing signals for synchronization and speed measurements, crucial for diagnostic analysis.
Industrial Applications: Widely used in industries such as oil and gas, petrochemicals, and municipal engineering to prevent catastrophic equipment failures.
