Typical applications include monitoring shaft vibration in turbines, compressors, pumps, and fans. Its fast NOT OK\/signal defeat response—output drops below 3.6 mA within 100 µs after a fault—makes it ideal for safety-critical environments like oil and gas, power generation, and petrochemical plants. The transmitter operates reliably in non-hazardous, Zone 2, or Division 2 hazardous areas when powered by a 28 V supply.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 990-10-70-01-00 on a standard 35 mm DIN rail using the included clips. Connect one non-contacting 3300 NSv proximity probe and extension cable to the input. Ensure the probe gap falls between 0.5 mm and 1.75 mm from the target to achieve full-scale range. Apply a +12 to +35 Vdc supply to the transmitter terminals; the maximum loop resistance including cable is 1,000 Ω at 35 Vdc. For optimal accuracy, use a 250 Ω loop resistance during calibration.\u003c\/p\u003e\u003ch2\u003eTroubleshooting \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eThe NOT OK\/signal defeat feature of the 990-10-70-01-00 activates when the probe or electronics detect an anomaly. If output drops below 3.6 mA, check the probe gap and cable integrity. A signal loss lasting more than 2-3 seconds indicates a persistent issue; verify the target material and probe tip condition. For frequency response deviations outside 5–6000 Hz, inspect the proximity probe and target surface. The non-interacting zero and span adjustments simplify field recalibration.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44416629604451,"sku":"990-10-70-01-00","price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/990-08-70-02-CN-1_92d8eee3-00d6-4425-b2d6-ad35912e6b53.jpg?v=1785248620","url":"https:\/\/www.plcsourcepro.com\/products\/bently-nevada-990-10-70-01-00-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
