This device accepts a non-contacting 3300 NSv proximity probe and provides a 4-20 mA output proportional to the measured thrust. With a linear range suitable for 0.6-0-0.6 mm or 25-0-25 mils, it delivers reliable performance in critical applications. A key failure-mode feature is the Not OK signal defeat, which forces the output below 3.6 mA within 100 µs upon detecting a fault, ensuring downstream safety systems respond promptly.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e+12 to +35 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoop Accuracy\u003c\/td\u003e\n\u003ctd\u003e±1.5% of full scale (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Loop Resistance\u003c\/td\u003e\n\u003ctd\u003e1,000 Ω at 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\u003eLinear Range (Prox Out)\u003c\/td\u003e\n\u003ctd\u003e0.25 to 1.65 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-35°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-51°C to +100°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.43 kg (0.9 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eThese specifications are directly from the Bently Nevada 991-06-70-02-01 datasheet and ensure precise vibration monitoring in harsh environments.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 991-06-70-02-01 is ideal for axial thrust monitoring in steam turbines, compressors, and large centrifugal pumps. Its robust design withstands extreme temperatures and provides a 4-20 mA signal directly to PLCs or DCS systems. The Not OK signal defeat feature makes it suitable for safety-critical installations where immediate fault indication is required.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 991-06-70-02-01 on a DIN rail and connect a compatible 3300 NSv proximity probe via extension cable. Wire the transmitter in a 2-wire 4-20 mA loop with a power supply between +12 and +35 Vdc. Use non-interacting external adjustments for zero and span. Ensure the bulkhead mounting option (Option 02) is correctly secured with screws. For optimal performance, maintain loop resistance below 1,000 Ω.\u003c\/p\u003e\u003ch2\u003eTroubleshooting and Common Issues\u003c\/h2\u003e\u003cp\u003eA common failure scenario is loss of probe signal. The Bently Nevada 991-06-70-02-01 handles this by driving the output below 3.6 mA within 100 µs. If the output remains high, check wiring and probe integrity. The current limiter (23 mA typical) prevents overload. For zero drift, use the external adjustments to recalibrate. Always verify the full-scale option (-06 for 0.6 mm) matches your application requirements.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eWhen ordering the Bently Nevada 991-06-70-02-01, confirm the system length option (-70 for 7.0 meters) and mounting option (02 bulkhead screws). Ensure your system's linear range matches the -06 full-scale option (0.6-0-0.6 mm). For reliable supply, contact PLC Source PRO at ubest101.myshopify.com. Always check agency approval (CSA Div 2) for hazardous environments.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44416835846243,"sku":"991-06-70-02-01","price":283.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.plcsourcepro.com\/products\/bently-nevada-991-06-70-02-01-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
