To maintain proper eddy-current probe scaling of 3.94 V\/mm (100 mV\/mil) typically associated with the 11 mm series, this 1.0-meter probe must connect to its matched 3300 XL 11 mm Proximitor sensor through a compatible extension cable, establishing a completed 5.0-meter or 9.0-meter electrical loop. Mechanical adjustment during installation is required to validate the gap voltage, targeting a baseline reading of -10 VDC at the physical center of the linear calibration range. This voltage stabilization enables the monitor rack to track dynamic rotor dynamics and shaft displacement while minimizing signal cross-talk suppression between adjacent probe assemblies.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Why does the 11 mm probe have a different scaling factor compared to the standard 8 mm probe?\u003c\/p\u003e\n\u003cp\u003eA: The larger 11.0 mm tip diameter generates a wider RF field, allowing for a broader linear range (typically 4.0 mm or 160 mils) than the 8 mm probe. Consequently, the linear scale factor decreases to 3.94 V\/mm (100 mV\/mil) to cover the wider physical gap range.\u003c\/p\u003e\n\u003cp\u003eQ: Can standard 8 mm cables and Proximitors be used with this 11 mm probe?\u003c\/p\u003e\n\u003cp\u003eA: No. The 11 mm probe has distinct physical and electrical properties. Using it with 8 mm Proximitors or mismatched extension cables will compromise the system impedance, leading to massive calibration errors and incorrect vibration readings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting and Torque:\u003c\/strong\u003e Thread the probe into the mounting sleeve. Do not exceed a tightening torque of 22.6 N-m (200 in-lb) for the 1\/2-20 UNF threads to prevent damaging the internal components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjusting the Gap Voltage:\u003c\/strong\u003e Slowly rotate the probe toward the shaft target while monitoring the Proximitor sensor output voltage.
