Ensure that the total electrical length of the probe and extension cable combined matches the calibrated length of your Proximitor sensor (typically 5.0 meters or 9.0 meters). Calibration settings require verification when swapping older 7200 series proximity probes due to differences in linear range and voltage scale factors (200 mV\/mil).\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eDuring mechanical installation, physical thermal expansion of the machine housing must be calculated. At high operating temperatures, turbine rotor growth can shift the nominal gap beyond the linear range of the sensor. The PPS tip is resilient against chemicals but susceptible to mechanical fracture; avoid direct impact during insertion through internal brackets. Ensure the fluorocarbon O-ring seal is seated properly inside the probe case to prevent pressure differential leakage.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eKeep the coaxial connector interfaces completely clean and free of moisture or lubricating grease. Any oil residue on the ClickLoc interface introduces high-frequency contact resistance, leading to false high-vibration readings or signal anomalies on the 3500 rack monitor. Secure the extension cable using non-conductive, self-locking clamps to prevent vibration-induced cable fatigue, ensuring the bend radius does not fall below 25.4 mm (1 inch).\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 De-energize and lock out all machinery before starting installation or mechanical adjustment.
