This 990 Vibration Transmitter accepts one non‑contacting 3300 NSv Proximity Probe and extension cable, converting shaft displacement into a standard 4‑20 mA signal. Designed for continuous operation in demanding industrial environments, the 990-05-70-03-CN helps extend equipment life and reduce unplanned maintenance expenses.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eKey performance parameters of the Bently Nevada 990-05-70-03-CN include:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull‑scale Range:\u003c\/strong\u003e 0–5 mils pp (0–125 µm pp) – Option 05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Length:\u003c\/strong\u003e 7.0 meters (23.0 feet) – Option 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e DIN clips and screws – Option 03\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Input:\u003c\/strong\u003e +12 to +35 Vdc at transmitter terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 4‑20 mAdc over full scale, 2‑wire configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoop Accuracy:\u003c\/strong\u003e ±1.5% over full scale (measured across 250 Ω, in addition to Prox Out Incremental Scale Factor)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Loop Resistance:\u003c\/strong\u003e 1,000 Ω including cable at 35 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting:\u003c\/strong\u003e 23 mA typical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 5 Hz to 6,000 Hz +0, 3 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter Weight:\u003c\/strong\u003e 0.43 kg (0.9 lbm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Target Size:\u003c\/strong\u003e 9.5 mm (0.375 in) diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Gap:\u003c\/strong\u003e 0.5–1.75 mm (20–55 mils) from target for full range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eReal‑World Applications\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-05-70-03-CN excels in critical rotating machinery monitoring. In a steam turbine installation, its 5 Hz to 6,000 Hz frequency response captures both low‑speed shaft bow and high‑speed blade‑pass vibrations. For a large centrifugal compressor, the 4‑20 mA loop output feeds directly into a DCS or PLC, enabling trending and alarm management. The 990-05-70-03-CN also supports predictive maintenance programs in paper mills, refineries, and power plants, where early detection of bearing wear or imbalance can save thousands in repair costs.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 990-05-70-03-CN using DIN clips and screws (option 03) on a standard DIN rail within a suitable enclosure. Connect a 3300 NSv Proximity Probe and extension cable to the input; the system length option 70 provides a 7.0‑meter cable. Wire the power supply (+12 to +35 Vdc) and the 4‑20 mA loop in a 2‑wire configuration. Adjust zero and span using the non‑interacting external adjustments. Ensure the probe gap is between 0.5 and 1.75 mm (20–55 mils) from the target to guarantee full‑scale output. For non‑hazardous, Zone 2 or Div 2 certified locations, power with a 28 V supply.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine checks of the Bently Nevada 990-05-70-03-CN focus on verifying the loop power supply remains within +12 to +35 Vdc and that the probe gap stays within specification. Inspect cable connections for corrosion or damage; the maximum leadwire length for the Proximitor Sensor Output (BNC connector) is 3 meters (10 feet). The transmitter’s signal defeat feature automatically drives the output below 3.6 mA within 100 µs of a Not OK condition, and restores it within 2–3 seconds after the fault clears. This self‑diagnostic capability minimizes false trips and enhances overall system reliability, directly supporting a positive ROI by reducing unplanned downtime.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering the Bently Nevada 990-05-70-03-CN, verify the full‑scale option (05: 0–5 mils pp), system length (70: 7.0 m), and mounting (03: DIN clips and screws). Confirm the agency approval option (CN) meets your regional requirements. The transmitter is made in the U.S.A.
