Bently Nevada 330851-05-000-040-10-00 3300 XL 25 mm Proximity Probe

产品介绍

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 / 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 imm件y 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 / 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.
