Integrated Reverse-Mount Monitoring Solution for Critical Rotating Equipment
The Bently Nevada 330881-16-06-165-07-02 PROXPAC® XL Reverse Mount Proximity Transducer Assembly is a factory-integrated machinery protection system designed to simplify installation while delivering precise shaft vibration and shaft position measurements for demanding industrial applications.
Unlike conventional proximity probe installations that require separate housings, extension cables, and external drivers, the PROXPAC XL architecture incorporates a 3300 XL 8 mm probe and an integrated Proximitor® sensor within a single enclosure, reducing installation complexity and minimizing field wiring requirements.
This reverse-mount configuration is particularly suitable for turbines, compressors, pumps, motors, and other critical rotating machinery operating in harsh industrial environments. The PROXPAC XL enclosure is engineered to provide robust environmental protection while simplifying maintenance access.
