As part of the 990 series, this unit provides a reliable, cost-effective solution for applications where a full-scale rack-based monitoring system is not required. It converts raw vibration signals into a proportional 4-20 mA output, allowing for direct integration into PLCs, DCS, or SCADA systems for machinery protection and condition monitoring.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFull-scale range: 0-4 mils pp (0-100 um pp)\u003c\/li\u003e\n\u003cli\u003eCable length: 7.0 meters (23.0 feet)\u003c\/li\u003e\n\u003cli\u003eMounting: Integrated 35 mm DIN rail clips for standard industrial cabinet installation\u003c\/li\u003e\n\u003cli\u003eAdjustments: Non-interacting external zero and span controls for precise calibration\u003c\/li\u003e\n\u003cli\u003ePower requirements: Operates on +12 to +35 Vdc input at the transmitter terminal\u003c\/li\u003e\n\u003cli\u003eCurrent limiting: 23 mA typical protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Model\u003c\/td\u003e\n\u003ctd\u003e990-04-70-01-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull-Scale Range\u003c\/td\u003e\n\u003ctd\u003e0-4 mils pp (0-100 um pp)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e7.0 meters (23.0 feet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Input\u003c\/td\u003e\n\u003ctd\u003e+12 to +35 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Limiting\u003c\/td\u003e\n\u003ctd\u003e23 mA typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.46 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the transmitter is mounted in a clean, dry environment within the specified temperature range.\u003c\/li\u003e\n\u003cli\u003eUse the provided 35 mm DIN rail clips for secure attachment to the equipment rack or panel.\u003c\/li\u003e\n\u003cli\u003eEnsure all wiring is shielded and routed away from high-voltage power lines to prevent EMI\/RFI interference.\u003c\/li\u003e\n\u003cli\u003eVerify correct polarity of the +12 to +35 Vdc power supply before applying power to the terminal.\u003c\/li\u003e\n\u003cli\u003ePerform calibration using the external zero and span adjustments only after the system has reached thermal equilibrium.\u003c\/li\u003e\n\u003cli\u003eAlways disconnect power before installing or removing the module from the DIN rail.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 990 vibration transmitter?\u003c\/h3\u003e\u003cp\u003eThe 990 transmitter is designed to monitor radial vibration on rotating machinery and provide a 4-20 mA output signal proportional to the vibration level, which is ideal for simple monitoring applications.\u003c\/p\u003e\u003ch3\u003eCan the zero and span be adjusted on this unit?\u003c\/h3\u003e\u003cp\u003eYes, the 990-04-70-01-00 features non-interacting external adjustments that allow for precise calibration of the zero and span settings without affecting the other parameter.\u003c\/p\u003e\u003ch3\u003eWhat type of mounting does this model support?\u003c\/h3\u003e\u003cp\u003eThis specific model is configured with 35 mm DIN rail clips for standard industrial mounting.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":50915198632188,"sku":"990-04-70-01-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_34eccd7a-87f9-4243-9604-a1f18cfe7042.jpg?v=1785816434","url":"https:\/\/www.electronicplc.com\/ar\/products\/bently-nevada-990-04-70-01-00-990-vibration-transmitter","provider":"Electronic PLC","version":"1.0","type":"link"}
