As a critical evolution of the 3300 XL transducer family, the 11mm system provides a wider linear range of 4.0 mm (160 mils), making it the definitive choice for monitoring axial position and thrust on large-scale rotating machinery.\u003c\/p\u003e\n\u003cp\u003eThis probe excels in high-stakes industrial environments such as utility-scale steam turbines and heavy-duty compressors. It accurately tracks shaft movement in real-time, feeding high-fidelity signals to the Bently Nevada 3500 monitoring rack or DCS. By utilizing a larger 11mm tip, this sensor significantly reduces the \"side-viewing\" effects often encountered with smaller probes, ensuring absolute measurement stability and preventing false trips in complex Turbine Supervisory Instrumentation (TSI) setups.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eModel Configuration \u0026amp; Hardware Logic\u003c\/h2\u003e\n\u003ch3\u003e330702-20-30-10-01-05 Suffix Decoding\u003c\/h3\u003e\n\u003cp\u003eEach parameter in this model number specifies the physical build and regulatory compliance required for heavy-industrial deployment.\u003c\/p\u003e\n\u003ch3\u003eUnthreaded Length (-20)\u003c\/h3\u003e\n\u003cp\u003eThis indicates an unthreaded length of 2.0 inches.
