As a core component of the 3300 XL Transducer System, this probe is specialized for large-scale machinery monitoring, offering an extended linear range and a standard output of 3.94 V\/mm (100 mV\/mil). It is designed to provide non-contacting displacement measurements for critical parameters such as differential expansion and axial position. By utilizing a reverse-mount mechanical interface, it allows technicians to install or replace the sensor from the outside of the machine housing, significantly reducing maintenance downtime for large rotating assets.\u003c\/p\u003e\n\u003ch3\u003eHardware Architecture and Mechanical Data\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eProbe Tip Diameter:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e11mm High-Performance Core\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Interface:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eM10 x 1 Metric Threads (Standard Reverse Mount)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIntegrated Lead Length:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1.0 Meter (approx. 3.3 feet)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConnector System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eGold-plated brass Miniature ClickLoc coaxial connector\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eExtended linear range for large displacement tracking\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3.94 V\/mm (100 mV\/mil) when paired with 3300 XL 11mm Proximitor\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNet Weight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.06 kg (0.13 lbs)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Dimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1.8 cm x 1.6 cm x 123 cm total length\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturing Standards:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRobust construction for high-vibration environments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eEnvironmental Resilience:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEngineered for oil-rich and high-temperature turbine environments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePrimary Industrial Deployment Scenarios\u003c\/h3\u003e\n\u003ch3\u003eSteam Turbine Differential Expansion\u003c\/h3\u003e\n\u003cp\u003eThe 11mm tip provides the wide linear range necessary to monitor the thermal growth difference between a steam turbine rotor and its casing, preventing catastrophic internal contact during startup and shutdown cycles.\u003c\/p\u003e\n\u003ch3\u003eLarge Compressor Axial Position\u003c\/h3\u003e\n\u003cp\u003eUsed to detect thrust bearing wear in high-pressure compressors.
