Engineered specifically for applications requiring a larger linear measurement range than standard 8 mm probes, this transducer system is essential for monitoring shaft vibration, position, and eccentricity in high-capacity rotating machinery. By utilizing the proven eddy-current measurement principle, the 11 mm system offers an extended linear range of 4.0 mm (160 mils), making it the ideal choice for large turbines, gearboxes, and industrial fans where greater thermal expansion or mechanical clearances are expected.\u003c\/p\u003e\n\u003cp\u003eDesigned for seamless integration into the Bently Nevada 3500 Machinery Protection System, the 330710-000-050-02-00 transducer ensures that maintenance engineers receive accurate, real-time data regarding the health of mission-critical assets. Its robust design features a specialized probe tip and housing construction that maintains signal integrity even in chemically harsh and high-temperature environments. For engineers seeking a reliable path toward Predictive Maintenance (PdM) and enhanced machinery availability, this 11 mm probe provides the depth and precision necessary to detect early-stage mechanical degradation, effectively preventing costly unscheduled downtime.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr
