Proper installation requires gap voltage validation; installers must adjust the probe to achieve a nominal -10 VDC gap voltage target to ensure signal linearity. Rotor dynamics analysis depends on precise output; therefore, the probe must be mounted to prevent structural resonance. Cross-talk suppression must be observed during multi-probe installations, ensuring sufficient distance between transducer tips to prevent electromagnetic interference.\u003c\/p\u003e\n\u003ch3\u003e## Ordering info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1x 21474-075-00 Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Probe connector protective cover\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Installation technical manual\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eAlignment: Ensure the probe is mounted perpendicular to the target surface.

No, 2000 series probes are designed for specific legacy monitors; impedance mismatches may occur with newer system components.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is the linear range defined? The range is defined by the distance over which the probe output remains proportional to the target displacement, typically 80 mils.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan I cut the probe cable? No, the probe and cable are an integrated, factory-calibrated assembly; cutting the cable invalidates the sensitivity and performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the recommended target material? Calibration is based on 4140 steel; other conductive materials will require re-scaling factors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan the probe measure shaft speed? Yes, when configured with a target keyway or notch, the voltage pulses generated can be processed for rotational speed measurement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat happens if the probe tip is damaged?
