Over-tightening 1\/2–13 UNC studs can strip housing threads or distort the sensor base, inducing base strain sensitivity errors (0.005 in\/s\/mstrain). Field engineers should always use a calibrated torque wrench within the 32–46 kg cm window and verify that the mounting pad is flat to within 2 mils to ensure true broad-frequency response without phase distortion.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/330500_2.png?v=1787033119\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45013952594102,"sku":"330500-08-01","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/BentlyNevada330500_1.jpg?v=1787033495","url":"https:\/\/www.plcsparehub.com\/products\/330500-08-01-bently-nevada-velomitor-piezo-velocity-sensor-module","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
