This industrial automation module is part of the 3300 XL series, designed for reliable proximity measurements in rotating machinery. The 330191-00-70-20-CN incorporates patented TipLoc molding to bond the probe tip securely and CableLoc technology for 330 N (75 lbf) pull strength on the probe cable. These innovations directly address common failure modes in eddy current probes.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 330191-00-70-20-CN operates with a power requirement of -17.5 Vdc to -26 Vdc when using a nonincendive circuit (per drawing 140979), with current consumption at 12 mA maximum. For barrier installations, the voltage range is -23 Vdc to -26 Vdc. The supply sensitivity is less than 2 mV change per volt change in input voltage, ensuring stable output. Output resistance is 50 Ω. The nominal probe DC resistance (RPROBE) is 7.88 ± 0.50 Ω for the 2.0 meter length. The probe tip is made of polyphenylene sulfide (PPS) and the case is AISI 303 or 304 stainless steel. Standard cable is 75 Ω triaxial FEP insulated; extended temperature cable uses PFA insulation. Maximum tensile strength is 330 N (75 lbf) from probe case to probe lead, and 270 N (60 lbf) at the extension cable connector. Connector material is gold-plated brass or beryllium copper, with maximum connector torque of 0.565 N•m (5 in•lbf). The 3\/8-24 UNF thread has a maximum engagement length of 0.563 inches. Weight is 323 g\/m (11.4 oz).\u003c\/p\u003e\u003ch3\u003eTemperature Ratings\u003c\/h3\u003e\u003cp\u003eFor EPL Ga and Gc, ambient temperature classifications range from T1 (-55°C to +232°C) down to T5 (-55°C to +40°C). For EPL Dc, the schedule includes T280°C at Ta -55°C to +232°C through T90°C at Ta -55°C to +40°C.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 330191-00-70-20-CN is ideal for monitoring radial vibration and shaft position in turbines, compressors, pumps, and motors. In petrochemical plants, the FluidLoc cable option prevents oil leakage from the machine through the cable interior, reducing maintenance. The 8 mm probe's thicker PPS encapsulation and larger diameter provide extra robustness against physical abuse in harsh environments. Because of the patented TipLoc and CableLoc designs, the 330191-00-70-20-CN reduces downtime caused by probe failures, aligning with a failure-prevention strategy.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eWhen installing the Bently Nevada 330191-00-70-20-CN, ensure the probe case threads engage correctly with the 3\/8-24 UNF mounting hole. The unthreaded length option for this model is 0.0 inches, with an overall case length of 7 inches. Use a torque of 0.565 N•m on the connector. For one-meter systems, no extension cable is required; for longer runs, use the appropriate BN extension cables. The probe seals differential pressure with a Viton O-ring, but note that probes are not pressure tested before shipment. Verify that the power supply delivers the required voltage range; operating more positive than -23.5 Vdc may reduce linear range.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 330191-00-70-20-CN integrates seamlessly with Bently Nevada extension cables and proximitors (BN Prox). The entity parameters are satisfied only when using BN extension cables with BN Prox. This probe works with standard Bently Nevada monitoring systems for vibration and position measurement. The 75 Ω triaxial cable ensures signal integrity over distances up to 9 meters (standard) or 9 meters (extended temperature).\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Bently Nevada 330191-00-70-20-CN, verify the total probe length (2.0 meters) and the agency approval (Country Specific Approval). Choose between standard or extended temperature range cable and optional armor. For optimal robustness against physical abuse, the 8 mm probe is recommended. PLC Source PRO offers this model in new, original factory packing with a 12-month warranty. Confirm compatibility with your existing monitoring system and extension cable lengths to ensure proper system integration.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44426725687395,"sku":"330191-00-70-20-CN","price":283.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/330191_202-10_6bead0df-39c5-465c-a26b-b964a0e718e6.jpg?v=1785454855","url":"https:\/\/www.plcsourcepro.com\/he\/products\/bently-nevada-330191-00-70-20-cn-3300-xl-8mm-etr-proximity-probe","provider":"PLC Source PRO","version":"1.0","type":"link"}
