Typical loop load is defined by the monitor's Proximitor interface; the transducer itself presents a fixed impedance probe coil (~50 to ~550 Ohm depending on gap).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs the PPS housing conductive for EMI shielding?\u003c\/p\u003e\n\u003cp\u003eYes. The Polyphenylene Sulfide (PPS) incorporates conductive fibers to strengthen the structure and dissipate electrostatic charges, but it does not replace metallic Faraday shielding. Proper cable shielding termination is required.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan a standard 3300 XL extension cable be added between the probe and housing?\u003c\/p\u003e\n\u003cp\u003eNo. The PROXPAC XL integrates the probe, extension cable, and Proximitor into a single housing. No separate extension cable is used or supported between the probe and sensor inside the assembly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat gap voltage range is valid for commissioning?\u003c\/p\u003e\n\u003cp\u003eTypical gap voltage validation uses -9 to -11 VDC at installed position. The -10 VDC nominal target corresponds to mid-linear range of the 8 mm probe (approx 1 mm gap). Field adjustment must follow the monitor's bias voltage verification procedure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes the M20 fitting support conduit entry?\u003c\/p\u003e\n\u003cp\u003eYes. The -03 option provides one M20 fitting with two plugs for cable entry or conduit adaptation. Use only metric glands rated for IP66\/Type 4X to maintain enclosure integrity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs the 160 mm standoff adapter fixed or removable?\u003c\/p\u003e\n\u003cp\u003eThe standoff adapter option defines the assembly configuration. In 330881 PROXPAC XL, the housing and adapter are configured per order code; mechanical alteration in field is not supported and voids approval ratings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat happens if the probe penetration exceeds 155 mm specification?\u003c\/p\u003e\n\u003cp\u003eThe -155- suffix defines probe penetration length. Exceeding or modifying this changes the effective probe tip position relative to the standoff and may result in loss of linear measurement range or mechanical interference with rotor\/housing internals.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":46025805136045,"sku":"330881-28-16-155-03-02","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/xianxian_45_8ac9ea5a-78fd-4260-8781-600926961778.jpg?v=1783667282","url":"https:\/\/www.maxwellplc.com\/ru\/products\/330881-28-16-155-03-02-bently-nevada-proxpac-xl-proximity-transducer-metric","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
