To ensure accurate rotor dynamics analysis, installers must perform gap voltage validation, targeting a -10 VDC setpoint at the monitor output. Cross-talk suppression is critical in multi-probe installations; maintain a minimum clearance of 40 mm between adjacent probe tips to prevent 1 MHz carrier frequency interference, which could otherwise introduce harmonic noise into the vibration data stream.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x 330881-28-08-050-03-02 PROXPAC XL Assembly\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Mounting accessory kit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Technical documentation\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 Mounting: Secure the integrated housing to a rigid, vibration-isolated surface to prevent structural resonance within the transducer assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignal Cabling: Utilize grounded metallic conduit for the output signal cable to provide robust shielding against electromagnetic interference.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnection Integrity: Verify all internal connections are factory-sealed; ensure the external output connector is fully seated and locked.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGrounding: Establish a low-impedance connection to the machine instrument earth to prevent ground loop currents that affect signal stability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGap Adjustment: Use a feeler gauge to set the initial probe gap, then verify the voltage reading at the Proximitor test point during cold-state commissioning.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Why is the PROXPAC XL considered an \"integrated\" system?\u003c\/p\u003e\n\u003cp\u003eA: It houses the Proximitor sensor and probe interface within a single protective enclosure, reducing field wiring complexity and environmental exposure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Can the probe tip be replaced if damaged?\u003c\/p\u003e\n\u003cp\u003eA: No. The PROXPAC XL is a factory-calibrated assembly; any mechanical damage to the tip or cable requires replacement of the entire unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Is the system sensitive to target material?\u003c\/p\u003e\n\u003cp\u003eA: Yes, calibration is optimized for 4140 steel.
