It is electrically incompatible with standard 3300 XL 8 mm, 11 mm, or 25 mm systems.

Despite the FluidLoc construction preventing capillary-action fluid migration, constant mechanical vibration can wear through the armor and outer jacket, resulting in ground loops or intermittent shield-to-ground faults. Observe a minimum bend radius of 25.4 mm (1.0 inch) for armored cables during route planning.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eVerify the absolute electrical physical system length (probe plus any extension cable) matches the Proximitor's calibrated length rating of 5.0 meters. Mismatched system lengths will distort the RF scale factor, causing significant linearity errors across the probe's expanded measurement range. Clean all coaxial connectors with a zero-residue contact cleaner and secure the connection using the recommended connector protector kits to prevent oil ingress at the junction point.\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; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Before starting installation, ensure all machinery is completely shut down, locked out, and tagged out (LOTO).
