A normal uninstalled 3300 XL 8 mm probe with a 2.0m cable typically reads between 5.0 Ω and 11.0 Ω.

Measuring shafts composed of alternative alloys, such as stainless steel or aluminum, requires target-specific recalibration or the application of an electronic correction factor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat specific hazardous locations is the \"05\" approval option certified for?\u003c\/p\u003e\n\u003cp\u003eThe \"05\" multi-approval choice combines ATEX, IECEx, and North American CSA certifications. It permits installation in intrinsically safe and non-incendive configurations across Zone 0, Zone 1, Zone 2, and Class I, Division 1 or 2 areas globally.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518848032941,"sku":"330101-00-48-20-12-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330101-00-48-20-12-05-3300-xl-8-mm-proximity-probes-r2k2awb1xtj.jpg?v=1766980359","url":"https:\/\/www.maxwellplc.com\/products\/330101-00-48-20-12-05-bently-nevada-proximity-probes-3300-xl","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
