Présentation du produit
The Bently Nevada 330851-05-000-040-10-00 3300 XL 25 mm Proximity Probe is a precision-engineered, non-contact displacement transducer designed for continuous machinery monitoring and protection. As part sur the Bently Nevada 3300 XL Series, it represents the industry standard for reliability, stability, and accuracy in proximity measurement technology.
This probe is specially optimized for large shaft and heavy-duty machinery applications, providing a 25 mm linear measurement range that allows accurate vibration and displacement detection in turbines, generators, compressors, and large electric motors. Utilizing the eddy current principle, it converts shaft motion into a proportional voltage signal, which is processed by the matching proximity sensor and extension cable to provide real-time measurement feedback.
The 330851-05-000-040-10-00 model is manufactured to meet API 670 requirements, ensuring high measurement integrity, repeatability, and interchangeability across systems. It is built from corrosion-resistant stainless steel and designed for harsh industrial environments, with high immunitéy to electromagnetic interference (EMI) and radio-frequency interference (RFI).
The probe forms a key component in the Bently Nevada 3300 XL 25 mm Transducer System, which includes the probe, extension cable, and proximity sensor. Together, they provide a standard system output sur 7.87 V/mm (200 mV/mil), making it fully compatible with Bently Nevada’s 3500 Monitoring System and other protection platforms used in rotating equipment diagnostics.
