Utilizing advanced eddy-current sensing technology, the 11 mm probe architecture offers a broader linear range compared to standard 8 mm probes, making it the preferred choice for machines with larger shaft orbits or lower-frequency displacement requirements.\u003c\/p\u003e\n\u003cp\u003eAs a core component of the Bently Nevada 3300 XL transducer system, this probe is engineered for extreme reliability in harsh environments. It features the patented TipLoc design, ensuring a permanent, high-strength bond between the sensor tip and the probe body. This construction effectively prevents the \"tip separation\" common in high-vibration applications. Compliant with API 670 standards, the 330708-00-20-50-02-00 is widely used in mission-critical TSI (Turbine Supervisory Instrumentation) environments, providing the stable, high-fidelity signals
