To maintain the linear output characteristics defined by the Incremental Scale Factor, the sensor must be installed at a nominal 0.5 mm air gap. Validation of the gap voltage is required during commissioning to ensure the probe operates within the linear segment of the transducer curve. Effective rotor dynamics monitoring further necessitates strict cross-talk suppression by maintaining sufficient physical separation between adjacent probes, preventing interference from overlapping carrier frequency magnetic fields.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is this sensor compatible with target materials other than ferromagnetic steel?\u003c\/p\u003e\n\u003cp\u003eA: No, the sensor is factory-calibrated exclusively for 42CrMo4 or AISI 4140 steel. Using materials with different magnetic permeability or electrical conductivity will introduce non-linearities and degrade measurement accuracy.\u003c\/p\u003e\n\u003cp\u003eQ: Can the cable length be modified without recalibrating the system?\u003c\/p\u003e\n\u003cp\u003eA: No, the sensor and cable act as a tuned circuit. Modifying the cable length alters the capacitive and inductive load, which shifts the carrier frequency and necessitates recalibration of the signal converter.\u003c\/p\u003e\n\u003cp\u003eQ: What is the risk of operating the sensor tip beyond the 200 deg C limit?\u003c\/p\u003e\n\u003cp\u003eA: Exposure to temperatures exceeding 200 deg C will cause thermal degradation of the PEEK tip and the internal coil potting, leading to signal instability, calibration drift, and premature failure of the hermetic seal.\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 sensor in a rigid, vibration-isolated bracket using the stainless steel threaded body.
