During commissioning, perform gap voltage validation (-10 VDC targets) to ensure the sensor operates within the linear portion of its output curve. For applications involving multiple probes, utilize adequate physical separation to ensure cross-talk suppression between individual oscillator circuits. If the probe exhibits non-linear output, verify the eddy-current probe scaling against the target rotor material; the 3300 XL system is factory-calibrated for 4140 steel, and deviations in target material properties will necessitate secondary scaling adjustments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Can the integral 3.7 m cable be spliced if it is too long for the specific installation path?\u003c\/p\u003e\n\u003cp\u003eA: No. Splicing or modifying the cable length alters the electrical characteristics and capacitance of the measurement chain, which invalidates the calibration of the 3300 XL Proximitor and leads to erroneous vibration data.\u003c\/p\u003e\n\u003cp\u003eQ: How does the probe interface with the 3300 XL Proximitor to ensure signal integrity?\u003c\/p\u003e\n\u003cp\u003eA: The probe connects to the Proximitor via a high-frequency coaxial connector. The Proximitor drives the probe with a high-frequency carrier signal, and the system monitors the load changes caused by eddy currents induced in the shaft surface, which are then demodulated into a conditioned voltage output.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the probe using the M14 × 1.5 mounting thread. Ensure the probe tip is perpendicular to the shaft surface to avoid signal distortion.
