Ensure the 3300 NSv proximity probe is gapped between 0.5 and 1.75 mm from the target. Connect the extension cable and power supply (+12 to +35 Vdc) to the transmitter terminals. The 2-wire 4-20 mA loop connects directly to your monitoring system. For Non-Hazardous, Zone 2, or Div 2 locations, use a 28 V power supply as specified. Use non-interacting zero and span adjustments for calibration.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe 990-10-70-01-01 enhances your plant's reliability by providing continuous vibration monitoring. Its NOT OK\/signal defeat function forces the output below 3.6 mA within 100 µs upon fault detection, enabling immediate protective action. This fast response reduces the risk of catastrophic machine failure. With current limiting (23 mA typical) and robust construction (0.43 kg), the transmitter requires minimal routine inspection. Verify proper probe gap and loop resistance periodically to maintain measurement accuracy.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the Bently Nevada 990-10-70-01-01, confirm your system requires a 3300 NSv non-contacting probe and extension cable. Verify the full-scale option (0-10 mils pp) matches your vibration range. For installations in hazardous areas, ensure your facility meets CSA Division 2 requirements.
