Commissioning requires gap voltage validation; the transducer must be adjusted to a nominal -10 VDC operational setpoint at the monitor input to maintain performance within the linear sensing region. The internal design incorporates cross-talk suppression circuitry to preserve signal integrity in multi-transducer configurations. The integrated nature of this unit removes the requirement for remote Proximitor enclosures, reducing interconnection complexity in rotor dynamics and shaft centerline monitoring applications.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) 330881-28-04-090-03-02 PROXPAC XL Transducer.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRequired mounting nuts and lock washers.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTechnical compliance and installation documentation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eNote: Operation requires a stable -24 VDC power source for specified electrical output.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eMechanical Mounting: Mount the transducer through the machine casing; use a rigid bracket to prevent mechanical resonance that could bias vibration data.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGap Setting: Utilize a depth micrometer to verify the mechanical gap; monitor the DC output voltage at the signal terminal until the -10 VDC target is achieved.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCabling: Install signal cabling in shielded conduit or dedicated cable trays to prevent induction from high-voltage AC lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGrounding: Secure a low-impedance machine ground to the transducer housing to ensure consistent shielding of the internal signal circuit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTorque Management: Tighten jam nuts to prevent loosening during harmonic machine operation; verify lock washers are seated correctly.\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\u003eWhat is the primary operational advantage of the PROXPAC XL design?\u003c\/p\u003e\n\u003cp\u003eThe integration of probe and signal conditioner eliminates external extension cables, reducing installation space and simplifying the signal path to the monitor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan this transducer function without a Proximitor?\u003c\/p\u003e\n\u003cp\u003eThe signal conditioning electronics are already integrated within the housing, effectively making the unit a self-contained transducer system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the target gap voltage for this transducer?\u003c\/p\u003e\n\u003cp\u003eThe nominal gap is centered at -10 VDC to ensure the eddy-current sensing circuit operates in the center of its linear range.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs the 90 mm case length field-adjustable?\u003c\/p\u003e\n\u003cp\u003eNo. The length is a fixed mechanical parameter determined at the factory; physical modification will invalidate the calibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan I replace the internal probe if the tip is damaged?\u003c\/p\u003e\n\u003cp\u003eNo. The PROXPAC XL is a factory-sealed, integrated unit; structural damage to the tip or body requires complete assembly replacement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is operational health verified?\u003c\/p\u003e\n\u003cp\u003eHealth is monitored via the DC gap voltage; drifts outside of acceptable ranges typically indicate probe failure or electrical discontinuity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes the transducer require a specific target material?\u003c\/p\u003e\n\u003cp\u003eFactory calibration is based on 4140 steel; usage on alternative materials necessitates a scale factor adjustment to maintain linearity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAre there specific grounding requirements?\u003c\/p\u003e\n\u003cp\u003eThe transducer housing must maintain a low-impedance connection to the machine chassis to ensure effective EMI\/RFI shielding of the internal components.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518839808173,"sku":"330881-28-04-090-03-02","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330881-28-04-090-03-02-proxpac-xl-proximity-transducer-4pten0ivflm.jpg?v=1766980180","url":"https:\/\/www.maxwellplc.com\/ru\/products\/330881-28-04-090-03-02-bently-nevada-proximity-transducer-proxpac-xl","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
