Unlike eddy-current probes that require gap voltage validation (-10 VDC targets) to determine shaft position, this sensor outputs a continuous signal reflecting seismic intensity. Maintaining signal integrity requires rigorous cross-talk suppression; interface cabling must be shielded to prevent electromagnetic noise induction from peripheral high-power AC lines. The case-isolated design minimizes ground loop susceptibility, and the 316L stainless steel shell ensures structural integrity in harsh industrial environments.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the significance of the 46 kg cm mounting torque specification?\u003c\/p\u003e\n\u003cp\u003eA: The mounting torque is critical for ensuring a rigid mechanical coupling between the transducer base and the machine casing. Under-torquing leads to high-frequency attenuation and resonance errors, while exceeding 46 kg cm may deform the M8 x 1 threaded interface.\u003c\/p\u003e\n\u003cp\u003eQ: Is this sensor compatible with hazardous area installations?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the -05 suffix indicates multiple agency approvals, including CSA and ATEX. Verify all safety barriers and wiring requirements per the specific installation manual for the designated hazardous zone.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMachine the mounting surface to a flat, smooth finish to ensure a rigid, full-contact interface for the M8 x 1 mounting stud.\u003c\/li\u003e\n\u003cli\u003eApply a thin layer of light machine oil or silicone grease to the transducer base to facilitate high-frequency energy transfer.\u003c\/li\u003e\n\u003cli\u003eTighten the sensor into the mounting hole until the base is fully seated against the casing, not exceeding the 46 kg cm torque limit.\u003c\/li\u003e\n\u003cli\u003eRoute the 2-pin Mil-C-5015 cable away from high-current AC leads and variable frequency drive outputs to minimize potential electromagnetic noise.\u003c\/li\u003e\n\u003cli\u003eVerify the bias voltage at the monitoring system input terminals to confirm the sensor is correctly energized prior to machine startup.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43551804751962,"sku":"330500-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330500-04-00_ed38215d-6fa5-4d70-a007-95610b508b16.png?v=1782358906","url":"https:\/\/www.spareoil.com\/es\/products\/bently-nevada-330500-02-05-velomitor-piezo-velocity-sensor","provider":"SpareOil Automation","version":"1.0","type":"link"}
