Proper scaling of the acceleration signal is contingent upon the transducer sensitivity being correctly mapped within the monitoring system software. To maintain signal integrity, avoid ground loops by utilizing isolated mounting pads when the machine casing is at a different potential than the instrument common. The use of a 1\/4-28 UNF integral stud ensures a rigid mechanical coupling to the measurement surface, which is necessary to prevent high-frequency mechanical resonance that could artificially inflate the perceived vibration amplitude.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this accelerometer be used with any standard Bently Nevada vibration monitor?\u003c\/p\u003e\n\u003cp\u003eA: The sensor requires a constant current source (typically 24 VDC) provided by the host monitoring card. Ensure the monitor supports ICP-type transducers and is configured for the specific sensitivity of the 330400 unit.\u003c\/p\u003e\n\u003cp\u003eQ: Is there a specific torque requirement for the 1\/4-28 UNF mounting stud?\u003c\/p\u003e\n\u003cp\u003eA: Yes. To ensure a flat, rigid frequency response, tighten the stud to the manufacturer-specified torque value (typically 3.4 Nm). Overtightening may damage the stud threads, while undertightening causes attenuation of high-frequency data.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePrepare the mounting surface by ensuring it is flat, clean, and free of paint or oxidation to guarantee maximum contact area.\u003c\/li\u003e\n\u003cli\u003eUtilize a spot-facing tool if the mounting surface is curved to ensure the base of the accelerometer achieves full 360-degree contact.\u003c\/li\u003e\n\u003cli\u003eRoute signal cabling through shielded conduits to minimize electromagnetic interference from adjacent high-voltage power cables.\u003c\/li\u003e\n\u003cli\u003eEnsure the coaxial cable shield is grounded at the instrument end only to prevent circulating ground currents that induce low-frequency noise.\u003c\/li\u003e\n\u003cli\u003eApply a light coating of silicone grease to the mounting interface if the installation is in a high-humidity environment to prevent corrosion at the contact point.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43544918196314,"sku":"330400-01-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330400-01-05.png?v=1782282786","url":"https:\/\/www.spareoil.com\/es\/products\/330400-01-05-bently-nevada-accelerometer-acceleration-transducers","provider":"SpareOil Automation","version":"1.0","type":"link"}
