To ensure accurate rotor dynamics data, the transducer must be mounted to achieve a nominal gap voltage of -10 VDC. Deviation from this target influences the linearity of the output signal. Furthermore, cross-talk suppression must be implemented by maintaining minimum physical spacing between neighboring probes to avoid interference between high-frequency electromagnetic fields.\u003c\/p\u003e\n\u003ch3\u003e## Ordering info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1x 330881-28-05-080-00-02 PROXPAC XL Transducer\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Protective connector 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\u003cli\u003e\n\u003cp\u003e1x Calibration verification data sheet\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\u003eMechanical Interface: Ensure the mounting boss is drilled and tapped square to the shaft centerline to prevent angular alignment errors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTorque Protocol: Tighten the lock nut to 5.1 N-m (45 in-lb) to ensure mechanical stability.
