If over-torqued, the AISI 304 stainless steel case can warp or bind, which risks micro-fracturing the internal PEEK tip assembly or shifting the calibrated position of the inner coils.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ2: Why is the unarmored version selected over the armored triaxial probe alternative?\u003c\/strong\u003e\u003cbr\u003e\nA2: The unarmored version reduces the probe's weight to a light 230 grams and provides superior flexibility for routing through tight internal conduits. This makes it an ideal option for installations where external stainless steel armor is unnecessary, such as inside fully enclosed turbine housings or rigid outer pipe ducts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: How does the 25 mm probe tip cope with high-temperature spikes up to 250 °C?\u003c\/strong\u003e\u003cbr\u003e\nA3: The PEEK tip and PFA insulation are rated to withstand intermittent spikes up to +250 °C for up to 24 hours without melting or losing calibration. If a thermal spike lasts longer than this window, it can lead to dielectric breakdown, signal drift, and potential loss of the internal fluid seal.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":51050861068420,"sku":"330851-01-000-020-10-00-05","price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/330851-01-000-020-10-00-05.jpg?v=1781277336","url":"https:\/\/www.etowonauto.com\/products\/330851-01-000-020-10-00-05-bently-nevada-3300-xl-25mm-probe","provider":"Etowon Auto","version":"1.0","type":"link"}
