Calibration is internally matched for a 5.0-meter overall system configuration comprising probe, extension cable, and sensor. During field alignment, technicians verify proper gap voltage validation targeting -10 VDC at static shaft centerline to provide symmetrical dynamic headroom for transient vibration excursions and maximize cross-talk suppression in multi-channel rotor dynamics setups.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What requires the Proximitor sensor total length option (-50) to match cable length?\u003c\/p\u003e\n\u003cp\u003eA: The internal tank circuit oscillator is factory-tuned to the exact capacitance and inductance of a 5.0-meter system length.
