This integrated solution combines a 3300 XL 8 mm proximity probe and a Proximitor sensor into a single, ruggedized housing, specifically designed for industrial environments where a separate Proximitor mounting is impractical. This unit serves as an essential component for monitoring radial vibration, axial thrust, or Keyphasor signals on rotating machinery within 3500 or 3300 Machinery Protection Systems. This specific configuration features a 95 mm probe penetration, M24 X 3 mounting threads, and a specialized fitting kit (PG21 to PG11 reducer). The PROXPAC XL is engineered to simplify installation while providing the high-precision eddy-current measurement standard across the 3300 XL series.\u003c\/p\u003e\n\u003ch3\u003eTechnical
