The sensor head and its flexible unarmored cable are cradled within custom-cut, high-density shock protection foam liners inside a heavy-walled corrugated structural shell. This eliminates the risk of impact crimping, connector flattening, or drop damage during long-distance international air or sea cargo shipping.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eCan a 3300 XL 8 mm probe be connected directly to a legacy 7200 series Proximitor sensor?\u003c\/p\u003e\n\u003cp\u003eNo. The 3300 XL 8 mm system operates on a different electrical design, utilizing a standard scale factor of \u003cstrong\u003e7.87 V\/mm (200 mV\/mil)\u003c\/strong\u003e. Attempting to mix it with a 7200 series sensor will corrupt the linear range and destabilize the calibration. Always match the probe with a corresponding 3300 XL Proximitor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the maximum allowable physical distance between the proximity probe and the Proximitor sensor?\u003c\/p\u003e\n\u003cp\u003eThe total system electrical length must be strictly maintained at either \u003cstrong\u003e5.0 meters\u003c\/strong\u003e or \u003cstrong\u003e9.0 meters\u003c\/strong\u003e (determined by your Proximitor model). This total includes both the integrated probe cable and the extension cable. Altering this total length shifts the tuning frequency and introduces major measurement errors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does crosstalk affect closely mounted 330104 proximity probes, and how can it be avoided?\u003c\/p\u003e\n\u003cp\u003eWhen two probe tips are mounted too close together, their radio frequency (RF) fields intersect, causing signal modulation interference (crosstalk). To prevent this in radial vibration setups, maintain a minimum physical separation of \u003cstrong\u003e74 mm (2.9 in)\u003c\/strong\u003e between probe tips, or \u003cstrong\u003e40 mm (1.6 in)\u003c\/strong\u003e for axial position arrangements.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes the cable construction on the 330104 series restrict its minimum bend radius?\u003c\/p\u003e\n\u003cp\u003eYes. While this unarmored variant offers higher flexibility than armored versions, you must still maintain a strict minimum bend radius of \u003cstrong\u003e25.4 mm (1.0 in)\u003c\/strong\u003e during installation routing. Bending or kinking the coaxial cable past this threshold damages the internal coaxial shielding layers, altering system impedance and destroying accuracy.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow do you verify if a 330104 probe has suffered an internal short or open circuit in the field?\u003c\/p\u003e\n\u003cp\u003eYou can diagnose the probe's health using a standard digital multimeter to check resistance across the center conductor and the outer shield of the coaxial connector. A normal, uninstalled 3300 XL 8 mm probe typically reads between \u003cstrong\u003e5.0 Ω and 11.0 Ω\u003c\/strong\u003e (depending on the integrated cable length). A reading near 0 Ω indicates a short, while an infinite reading indicates an open circuit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518848065709,"sku":"330104-15-25-10-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330104-15-25-10-02-05-3300-xl-8-mm-proximity-probes-jw2at1nxmnq.jpg?v=1766980360","url":"https:\/\/www.maxwellplc.com\/products\/330104-15-25-10-02-05-bently-nevada-proximity-probes-3300-xl","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
