Gap Voltage Validation\u003c\/h3\u003e\n\u003cp\u003eThe 990 series integrates an internal Proximitor sensor calibrated specifically for 3300 NSv proximity probes. The transducer converts the raw eddy-current probe signal into a linearized 4-20 mA output with a nominal sensitivity of 200 mV\/mil at the Prox Out diagnostic port. Gap voltage must be validated to maintain the probe tip within 20 to 55 mils (0.5 to 1.75 mm) from the target surface to ensure linear operation. The Not OK \/ Signal Defeat circuit clamps the output to less than 3.6 mA within 100 microseconds upon detecting a faulty probe state or loose connection, preventing false machine trips during signal degradation events.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum cable resistance allowed in the 4-20 mA loop?\u003c\/p\u003e\n\u003cp\u003eA: The maximum loop resistance is 1,000 ohms total, including cable resistance, at 35 VDC supply voltage.\u003c\/p\u003e\n\u003cp\u003eQ: Does the transmitter support hot-swap replacement on DIN rail?\u003c\/p\u003e\n\u003cp\u003eA: The 2-wire loop-powered design requires loop power to be disconnected before removal or installation. The Power-Up Inhibit circuit clamps the output below 3.6 mA for 2 to 3 seconds upon startup to block line voltage transients.\u003c\/p\u003e\n\u003cp\u003eQ: What probe gap voltage range is required for linear operation?\u003c\/p\u003e\n\u003cp\u003eA: The probe gap must be maintained between 20 and 55 mils (0.5 to 1.75 mm) from the target surface for correct linear measurement.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the transmitter to a 35 mm DIN rail or use the supplied bulkhead mounting screws. Connect the 3300 NSv proximity probe and extension cable to the input terminals, ensuring the shield is properly grounded at the transmitter end. Wire the 4-20 mA output loop to the PLC, DCS, or SCADA analog input card, observing polarity. Adjust the Zero and Span potentiometers externally to calibrate the output against the 0-5 mils full-scale range. Verify the gap voltage is within the 20-55 mil window before commissioning. The potted construction tolerates 100% condensing humidity, but the unit must not be submerged.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44273165926488,"sku":"990-05-XX-03-05","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/990-05-XX-03-05-3.jpg?v=1782286607","url":"https:\/\/www.industriaxplc.com\/ar\/products\/series-vibration-transmitter-990-05-xx-03-05-bently-nevada","provider":"IndustriaX Limited","version":"1.0","type":"link"}
