The 330104‑00‑08‑50‑01‑05 is part of the 3300 XL 50 mm Proximity Transducer Series, designed for large-scale industrial rotating machinery monitoring. This series is built to provide reliable, high-accuracy measurements with extended cable options for complex installations.
The 330104‑00‑08‑50‑01‑05 is a 50 mm diameter eddy current proximity probe engineered for non-contact radial displacement and vibration monitoring in large industrial equipment. The probe features a medium-length cable for flexible installations, converting mechanical motion into a proportional voltage signal for real-time condition monitoring. Its stainless steel housing ensures durability under extreme industrial environments, including exposure to oils, dust, vibration, and high temperatures.
This model is optimized for integration with 3300 XL machinery protection systems and supports predictive maintenance strategies, helping detect imbalance, misalignment, and bearing wear before catastrophic failures occur.
