Engineered for heavy-duty industrial applications, this transducer system is optimized for monitoring large-clearance rotating machinery where standard 8 mm probes lack the required measurement depth. By leveraging advanced eddy-current technology, the 330704-000-100-10-01-CN provides a non-contact, highly stable displacement measurement that is essential for identifying shaft vibration, position, and eccentricity in critical assets.\u003c\/p\u003e\n\u003cp\u003eAs a primary sensor for turbomachinery protection, this unit plays a vital role in predictive maintenance programs by detecting early mechanical fatigue, bearing degradation, and shaft misalignment. The \"CN\" suffix designates its specific regulatory compliance, ensuring it meets rigorous quality and safety standards for the global market. Designed to operate seamlessly with the 3300 XL Proximitor sensor and high-quality extension cables, this probe delivers a linear range of 4.0 mm (160 mils), making it the ideal choice for massive industrial pumps, gas turbines, and compressors where thermal growth and mechanical clearances are significant. Whether integrated into a Bently Nevada 3500 monitoring system or utilized as a standalone diagnostic tool, this probe offers the reliability, precision, and longevity that instrumentation engineers
