Information

Overview Manuals Common Applications Product Precautions

The 330880-28-15-106-00-02 is an 11mm proximity probe from the 3300 XL series manufactured by Bently Nevada. This probe belongs to the eddy current sensor system and is specifically designed for high-precision, non-contact displacement and vibration monitoring of large rotating machinery, particularly in applications requiring a wide linear range.

One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor

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.

When using the 330880-28-15-106-00-02 probe, due to its 10.6-inch extra-long case, it is critical to ensure the mounting hole is clean and properly aligned to prevent casing deformation or internal coil damage from uneven stress during threading. Simultaneously, ensure the total system length strictly matches the 3300 XL 11mm Proximitor calibration, and use a multimeter to adjust the gap voltage to the linear midpoint (typically around -9V to -11V DC). Additionally, use connector protectors to prevent oil infiltration and strictly adhere to the minimum bend radius of the cable to ensure long-term stability in large displacement monitoring.
