If the application environment involves immersion in pressurized oil sumps or critical containment boundaries, user-side pressure verification or dynamic pressure-seal testing is highly recommended before commissioning.

Keep adjacent metal structures outside the projected RF sensing field (typically at least 3 probe tip diameters of radial spacing) to avoid false calibration shifts. When deploying the 9.0-meter option, never trim or splice the high-frequency coaxial cable; any alterations to the physical cable length will corrupt the electrical tuning of the system and degrade signal accuracy.\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  \u003cp style=\"color: #9b2c2c; margin: 0; font-weight: bold;\"\u003eCRITICAL WARNING: SAFETY FIRST\u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0.25rem 0 0 0;\"\u003eBefore starting mechanical mounting or loop connection, fully de-energize all connected machinery protection monitors.
