Bently Nevada 330880-28-15-044-01-02 PROXPAC XL Proximity Transducer

Description

The Bently Nevada 330880-28-15-044-01-02 is a PROXPAC XL Proximity Transducer Assembly designed for continuous vibration and shaft position monitoring on rotating machinery. The assembly integrates a 3300 XL 8 mm proximity probe with a 3300 XL Proximitor Sensor inside a single housing, providing a compact installation solution for machinery monitoring applications. The integrated design eliminates the need for a separate Proximitor Sensor housing and removes the requirement for an extension cable between the probe and sensor. Field wiring connects directly between the monitoring system and the PROXPAC XL assembly, simplifying installation and reducing the number of components required at the machine location. The 330880-28-15-044-01-02 configuration includes a 3300 XL 8 mm probe with multiple approvals, a 1.5 inch (38 mm) standoff adapter, a 4.4 inch probe penetration length, and a 3/4-14 NPT fitting configuration. It is suitable for applications where reliable proximity measurement is required for monitoring shaft vibration and position in critical rotating equipment.
