Attempting to disassemble or cut the junction destroys the moisture barrier and permanently disrupts calibration parameters.\u003c\/p\u003e\n\u003cp\u003eQ: Is a Proximitor Sensor required to run this high-temperature velomitor assembly?\u003c\/p\u003e\n\u003cp\u003eA: No. Unlike proximity elements that utilize eddy-current probe scaling, this is a seismic device. It wires directly into a standard velocity input channel of a 3500\/42M or equivalent machinery protection module, utilizing the standard constant-current power sourced by that monitor card.\u003c\/p\u003e\n\u003cp\u003eQ: What happens if the operating temperature at the sensor head passes the +400 deg C limit?\u003c\/p\u003e\n\u003cp\u003eA: Exceeding +400 deg C causes permanent depolarization of the internal piezoelectric crystals. This leads to a catastrophic loss of the nominal 150 mV\/in\/s scale factor, rendering the output data invalid and driving the monitoring rack into an permanent transducer fault state.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518832435373,"sku":"330750-60-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330750-60-05-high-temperature-velomitor-system-zdyy4p0y2c2.jpg?v=1766979891","url":"https:\/\/www.maxwellplc.com\/products\/330750-60-05-bently-nevada-velomitor-system-high-temperature-transducer","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
