When interfaced with CON-series transmitters, standard sensitivity achieves 8.0 V\/mm (200 mV\/mil) over ferromagnetic targets like 42CrMo4 steel. Initial mechanical setup requires accurate gap voltage validation, establishing a static DC bias near -10 VDC at the mid-scale position (1.0 mm gap) to ensure maximum dynamic linear headroom for vibration peak measurement. To prevent cross-talk suppression degradation, a minimum radial distance of 25 mm must be maintained between adjacent probe tips, and the PEEK sensing head requires at least 15 mm of unthreaded side clearance from surrounding metal housings.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the physical gap voltage validated during mechanical zeroing?\u003c\/p\u003e\n\u003cp\u003eA: Thread the probe into the mounting bracket while measuring the DC voltage output at the connected CON021\/CON031\/CON041 signal conditioner terminal.
