The Incremental Scale Factor (ISF) is specified at 7.87 mV\/um (200 mV\/mil) with a typical tolerance of +\/-6.5% at the Prox Out port. Gap voltage can be validated at the COM terminals, where a healthy probe gap typically presents a DC bias target of approximately -10 VDC. The transmitter provides dynamic vibration data extraction via a coaxial connector and dedicated PROX OUT \/ COM terminals for diagnostic verification using standard oscilloscopes or analyzers.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the probe length configuration for the XX suffix?\u003c\/p\u003e\n\u003cp\u003eA: The XX system length option must be specified at time of order as either 50 (5.0 meters) or 70 (7.0 meters), corresponding to the total probe and extension cable assembly length in the 3300 NSv system.\u003c\/p\u003e\n\u003cp\u003eQ: How does the Not OK circuit behave during probe failure?\u003c\/p\u003e\n\u003cp\u003eA: Upon probe disconnection or failure, the Not OK circuit forces the loop current below 3.6 mA within 100 microseconds, preventing false 4-20 mA alarm conditions in the downstream PLC or DCS.\u003c\/p\u003e\n\u003cp\u003eQ: Can the zero and span be adjusted in the field?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the transmitter features non-interacting external Zero and Span potentiometers accessible without disassembling the potted housing.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the transmitter to a standard 35 mm DIN rail using the supplied clips (option 03). Ensure the aluminum housing is seated firmly to maintain mechanical stability. Route the 3300 NSv proximity probe cable and extension cable with proper shielding, grounding the shield at the transmitter end only to prevent ground loops. The 4-20 mA output loop requires 12-35 VDC power supply at the transmitter terminals; verify polarity before connection. For dynamic diagnostic access, connect a coaxial cable to the PROX OUT connector or use the COM terminals for gap voltage measurement. The potted construction allows operation in 100% condensing humidity environments, but the unit must not be submerged.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44273174937688,"sku":"990-08-xx-03-00","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/990-08-xx-03-00-3.jpg?v=1782286840","url":"https:\/\/www.industriaxplc.com\/id\/products\/vibration-transmitter-990-08-xx-03-00-bently-nevada","provider":"IndustriaX Limited","version":"1.0","type":"link"}
