The 330880-28-45-020-03-02 is an 11mm proximity probe from the 3300 XL series manufactured by Bently Nevada. It is an industry-recognized standard component for rotating machinery conditions, specifically designed for high-precision non-contact seismic measurements.
Provides a robust electrical connection
Provides a linear measurement range of 4.0 mm
The probe tip is sealed with polyphenylene sulfide materia
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.

Paper & Pulp Industry
Monitoring radial clearance on high-speed vacuum pump shafts to prevent internal rubbing.
When using the 330880-28-45-020-03-02 probe, it is essential to ensure that the total system length (typically 5m or 9m) strictly matches the 3300 XL 11mm Proximitor and extension cable to maintain measurement accuracy. During installation, use a multimeter to precisely adjust the gap voltage to the linear midpoint and ensure the probe tip is free from metal debris contamination. Additionally, use connector protectors to prevent oil infiltration and strictly adhere to the minimum bend radius requirements for the cable to extend service life and prevent signal drift.
It is a Bently Nevada 3300 XL 11mm proximity probe used for non-contact measurement of vibration and displacement in rotating machinery.
What is the primary function of 330880-28-45-020-03-02?
Its primary function is to measure shaft vibration, axial position, and speed relative to the bearing housing.
What is the working principle of 330880-28-45-020-03-02?
It operates on the eddy current principle, where distance changes between the probe tip and the metal shaft are converted into voltage signals.
Can 330880-28-45-020-03-02 withstand extreme temperatures?
Yes, it is designed for harsh environments and can typically operate in temperatures up to 177°C (350°F).
What equipment must 330880-28-45-020-03-02 be used with?
It must be connected to a 3300 XL Proximitor Sensor and typically integrated into a 3500 Monitoring System.
