Designed for critical non-contact vibration and shaft position measurements in rotating machinery, this specific configuration features a fully threaded 3\/8-24 UNF body with zero unthreaded length (0.0 inches) and an overall case length of 4.8 inches. Notably, this variant is equipped with a 2.0-meter (6.6 feet) patented \u003cstrong\u003eFluidLoc cable\u003c\/strong\u003e and a miniature coaxial ClickLoc connector without a connector protector. The FluidLoc technology provides an internal barrier that prevents lubricating oils, process fluids, or gases from leaking or wicking through the core of the cable out of the machine housing, making it highly appropriate for fluid-submerged bearing environments. Additionally, this probe configuration comes certified with the -05 hazardous area agency approvals, covering ATEX, IECEx, and CSA standards for intrinsically safe installations.\u003c\/p\u003e\n\n\u003cp\u003eOperating on the eddy-current principle, this probe pairs with a 330180 series 3300 XL Proximitor sensor and an appropriate extension cable to form a complete 5-meter or 9-meter transducer chain. This system provides a linear output voltage directly proportional to the distance between the probe tip and the observed target, typically an AISI 4140 steel shaft. Known for its exceptional accuracy, robust thermal stability, and mechanical resilience, the 3300 XL system is the global standard for turbomachinery protection, including steam turbines, gas turbines, compressors, gearboxes, and pumps.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluidLoc Cable Technology:\u003c\/strong\u003e Patented coaxial cable design that prevents oils, moisture, and gases from leaking out of the machine casing through the cable interior.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully Threaded Body:\u003c\/strong\u003e Designed with a 0.0-inch unthreaded length and a 4.8-inch case length for direct, deep-reach mounting in tapped bearing housings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGold-Plated ClickLoc Connector:\u003c\/strong\u003e Miniature coaxial connector requires only finger-tight torque and resists loosening due to a positive lock mechanism.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Armor Option:\u003c\/strong\u003e Flexible and lightweight cable construction without outer steel armor, suitable for conduit routing or clean installation paths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntrinsically Safe Approvals:\u003c\/strong\u003e Certified with the -05 approval option, making it compliant with ATEX, IECEx, and CSA requirements for hazardous environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEddy Current Measurement:\u003c\/strong\u003e Delivers precise, non-contact measurement of shaft vibration and dynamic position.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThis proximity probe is ideal for demanding rotating machinery installations where process fluid containment is critical.
