The 330880-28-15-063-00-02 The design of the PROXPAC XL Proximity Transducer Assembly is similar to our 31000/32000 Proximity Probe Housing Assemblies. 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.
Simplified Field Installation
Exceptional Environmental Ruggedness
Precise & Robust Physical Configuration
The PROXPAC XL housing is made of Polyphenylene Sulfide (PPS), which is an advanced, molded thermoplastic. This material replaces the steel and aluminum in previous housings offered in the Bently Nevada product line. It also incorporates glass and conductive fibers in the PPS to strengthen the housing and more effectively dissipate electrostatic charges. The PROXPAC XL housing is rated for Type 4X and for IP66 environments and provides extra protection in severe environments.

Oil & Gas
This is the most widely used industry for this model. Because it has -02 multiple country certifications (ATEX/IECEx/CSA), it can be safely installed in areas with flammable and explosive gases.
Petrochemical & Chemical
Monitor the eccentricity of the mixing shaft or the vibration of the pump shaft. PPS material provides excellent chemical corrosion protection for the housing, and it will not rust or be damaged like metal housings even in environments filled with chemical acid mist.
Power Generation
Real-time monitoring of the thermal expansion displacement and rotational vibration of the unit rotor. The sleeve length of this 063 (6.3 inches) model is ideal for installation through the unit's insulation layer or thickened bearing housing.
Water Treatment & Pumping Stations
With its IP66/Type 4X high protection rating, this sensor can withstand high-pressure water jets and outdoor rain. The integrated design also simplifies the wiring complexity across large pump station areas.
Because this model has a 1.5-inch (38 mm) probe standoff and a 6.3-inch (160 mm) total sleeve length, strict impact prevention is required. The depth of the mounting hole must be accurately measured before screwing the sensor into the machine mounting hole. If the hole is less than 6.3 inches deep, the probe tip will directly hit the rotating shaft, causing expensive probe damage. Regarding coaxiality requirements, the mounting hole must be perpendicular to the shaft surface. If the installation is tilted, the gap measured by the probe will be inaccurate, resulting in linear distortion of the vibration readings.
What specific physical meaning does the '060' parameter in the model 330881-28-00-060-00-02 represent?
This 6.0 meters includes the total of the probe lead and the internal extension cable. Since the eddy current sensor is calibrated based on electrical characteristics, the system must strictly maintain this 6.0-meter length. Users must not shorten or extend the cable on their own, otherwise it will result in measurement accuracy failure.
When installing 330881-28-00-060-00-02, how can you determine that the probe is in the correct measurement position?
Use a multimeter to measure the output signal. The standard 3300 XL system linear range center point is usually set around -10.0 VDC. If the voltage deviates too much from this value when the machine is at rest (for example, only -2 V or over -18 V), it is necessary to adjust the probe depth through the adjustment thread on the Proxpac housing.
Can 330881-28-00-060-00-02 be used to measure shafts made of aluminum or stainless steel?
The system is factory-calibrated by default for AISI 4140 steel (ferromagnetic material). If the target material is aluminum (non-ferromagnetic) or certain stainless steels, the eddy current effect will change significantly, causing the proportional factor to no longer be $200$ mV/mil. If it must be used, material recalibration is required or a correction factor should be set in the host computer.
If the PPS housing of 330881-28-00-060-00-02 is damaged, can the housing be replaced alone without affecting the sensor's performance?
The PPS housing of the Proxpac XL serves protective and sealing functions. If only the housing is cracked but the internal proximitor and probe are intact, the housing can be replaced. However, because the interior involves precision connectors and waterproof sealing, it is recommended that professionals perform the operation. If the damage involves internal circuits, it is generally recommended to replace the entire integrated assembly to ensure measurement consistency.
For integrated designs like 330881-28-00-060-00-02, which part needs the most attention during regular inspections?
Since the preamplifier is right next to the machine, the environment is harsh. The cable gland should be checked for looseness to prevent water ingress. At the same time, the gap voltage should be recorded regularly. If the voltage drifts significantly over time, it may indicate a loose probe, bearing wear, or aging of the internal circuitry.
