To ensure data integrity for rotor dynamics analysis, the transducer sensitivity is calibrated to 2.5 mV\/m\/s^2. Maintaining amplitude linearity within the specified range of 735 m\/s^2 is required to prevent signal clipping or harmonic distortion. During installation, the integral 1\/4-28 UNF stud must be torqued to manufacturer specifications to ensure high-frequency response and prevent mechanical decoupling from the machine case. Proper coupling is required to maintain the signal path for monitoring non-synchronous and high-frequency vibration components effectively.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 330425-01-05 be installed on non-metallic machine casings?\u003c\/p\u003e\n\u003cp\u003eA: Installing accelerometers on non-metallic surfaces can attenuate high-frequency signals. For optimal response, the transducer should be mounted on a rigid, metallic surface that is part of the machine's structural frame.\u003c\/p\u003e\n\u003cp\u003eQ: Are there specific torque requirements for the integral mounting stud?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The integral 1\/4-28 UNF stud must be tightened to the recommended torque to achieve a rigid mechanical connection, ensuring the transducer frequency response remains within the defined flat operational bandwidth.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the mounting surface is flat, clean, and free of paint to maximize surface contact for the sensor base.\u003c\/li\u003e\n\u003cli\u003eApply a thin layer of silicone grease or oil to the mating surface before installation to improve high-frequency transmission.\u003c\/li\u003e\n\u003cli\u003eTighten the 1\/4-28 UNF stud to the specified torque value; excessive torque may damage the stud or the mounting hole, while insufficient torque reduces frequency response.\u003c\/li\u003e\n\u003cli\u003eRoute the transducer cable through a flexible conduit to protect against environmental damage while ensuring the cable remains isolated from high-voltage AC lines to prevent EMI.\u003c\/li\u003e\n\u003cli\u003eVerify that the transducer cable shield is grounded at the monitor interface to maintain signal signal-to-noise ratio.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43537086971994,"sku":"330425-01-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330425-01-05.png?v=1782195305","url":"https:\/\/www.spareoil.com\/products\/330425-01-05-bently-nevada-accelerometer-acceleration-transducers","provider":"SpareOil Automation","version":"1.0","type":"link"}
