However, field engineers must note that while the probe is mechanically compatible, mixing XL and non-XL system components (such as combining a 3300 XL probe with a legacy 3300 Proximitor Sensor) can degrade the system's temperature stability and slightly alter the Scale Factor (normally 7.87 V\/mm or 200 mV\/mil). For critical TSI (Turbine Supervisory Instrumentation) loops, maintain matched 3300 XL hardware across the probe, extension cable, and Proximitor sensor.\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo prevent spatial signal distortion, ensure a minimum clearance of 15.2 mm (0.6 in) around the probe tip from any adjacent metallic objects. Mounting the probe tip too close to structural brackets or dynamic shaft collars will cause the RF field to couple with non-target metal, leading to false displacement readings. Additionally, ensure the FEP cable is not subjected to a bend radius smaller than 25.4 mm (1.0 in) during routing to prevent core-to-shield shorting and signal attenuation under thermal cycling.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen routing the probe cable through machine casings, always use dynamic conduit or protective sleeving to protect the FEP jacket from sharp metal edges and process fluids. Use a dedicated connector protector kit when snapping the ClickLoc coaxial connector together. Ensure the connection is completely free of moisture, oil, or thread sealant before mating, as any chemical contamination inside the connector will degrade the high-frequency impedance, resulting in intermitent \"Sensor Limit\" or \"OK\" circuit faults at the monitoring rack.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING: SAFETY FIRST\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003ePrior to installing or adjusting any proximity probe, ensure the target machinery is completely de-energized, locked out, and tagged out.
