Bently Nevada 330851-04-002-010-00-05 3300 XL 25 mm Proximity Probe

مقدمة المنتج

The Bently Nevada 330851-04-002-010-00-05 3300 XL 25 mm Proximity Probe is a precision-engineered, non-contact displacement transducer designed for the monitoring and protection من large and critical rotating machinery. As part من the 3300 XL series, it provides accurate, linear, and stable measurements من shaft vibration, radial position, and axial displacement.

This model is specifically optimized for large shaft applications, منfering a 25 mm linear range that exceeds the capability من standard probes such as the 8 mm and 11 mm versions. It is used extensively in heavy-duty turbines, generators, compressors, and large motors where shaft size and displacement amplitude are significant.

The 330851 series utilizes eddy current sensing technology to convert the distance between the probe tip and the target surface into a proportional voltage output. When paired with the matching 3300 XL extension cable and proximity sensor, it forms a complete transducer system that delivers a standard output من 7.87 V/mm (200 mV/mil), fully compliant with API 670 requirements for machine condition monitoring and protection.

The probe’s construction features high-quality stainless steel housing and hermetically sealed design, ensuring excellent resistance to moisture, oil, and corrosive industrial environments. Its durability and measurement accuracy make it a trusted choice for long-term monitoring in critical machinery protection systems.
