Ensure the proximity probe is gapped between 0.5 and 1.75 mm from the target. Connect the 3300 NSv probe and extension cable to the input. The system length option 50 indicates a 5.0-meter cable. Power the unit with +12 to +35 Vdc at the transmitter terminal. The 4-20 mA output loop can include up to 1,000 Ω resistance. The BNC connector for the Proximitor Sensor Output must not exceed 3 meters in cable length.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-08-50-02-CN Vibration Transmitter features a NOT OK\/signal defeat function: if a fault occurs, output drops below 3.6 mA within 100 μs, and restores within 2-3 seconds after the fault clears. This provides immediate alarm indication for predictive maintenance. Regular inspection of probe gap and cable connections ensures reliable operation. The transmitter's current limiting (23 mA typical) protects against loop faults.\u003c\/p\u003e\u003ch2\u003eTroubleshooting \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eIf the output is erratic, verify the probe gap is within 0.5-1.75 mm and the target size meets the minimum 9.5 mm diameter. Check the loop resistance does not exceed 1,000 Ω at 35 Vdc. If the signal goes below 3.6 mA, a Not OK condition exists – inspect probe and wiring. The frequency response of 5 Hz to 6,000 Hz covers typical machine vibrations. Ensure the power supply provides stable +12 to +35 Vdc.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting the Bently Nevada 990-08-50-02-CN Vibration Transmitter, verify the full-scale option (08: 0-8 mils) and system length (50: 5.0 m) match your application. For reliable supply, consider purchasing from PLC Source PRO (available through ubest101). This transmitter is ideal for continuous vibration monitoring in industrial environments.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44416608632931,"sku":"990-08-50-02-CN","price":272.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/990-08-70-02-CN-1_c63b7388-e24d-4bb4-a624-2ff30c615f70.jpg?v=1785246466","url":"https:\/\/www.plcsourcepro.com\/products\/bently-nevada-990-08-50-02-cn-vibration-transmitter","provider":"PLC Source PRO","version":"1.0","type":"link"}
