It directly replaces older Bently Nevada transmitters without requiring wiring changes, thanks to its 2-wire 4-20 mA configuration. Use it in non-hazardous, Zone 2, or Div 2 hazardous areas with a 28 V power supply. The small form factor and DIN rail mounting simplify installation in crowded panels.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 990-05-50-03-01 using the included DIN clips and screws (Mounting Option 03). Ensure the 3300 NSv probe is gapped between 0.5 and 1.75 mm from the target surface. Connect the probe and extension cable to the transmitter input. Apply +12 to +35 Vdc power at the transmitter terminal. The 4-20 mA output connects in series with a loop resistance up to 1,000 Ω. Adjust zero and span using non-interacting external trimmers. Verify the probe gap and full-scale range before commissioning.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 990-05-50-03-01 requires minimal maintenance. Periodically check the probe gap and cable connections. The current limiting (23 mA typical) protects against loop faults. The NOT OK signal defeat forces output below 3.6 mA within 100 μs of a fault, with automatic recovery in 2-3 seconds. This ensures fail-safe operation. For long-term reliability, keep the transmitter in a clean, dry environment within its specified temperature range (not explicitly stated, but typical for industrial modules).\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen replacing an existing vibration transmitter, verify the full-scale range (Option 05: 0-5 mils pp) matches your application. The system length option (50: 5.0 meters) determines cable length. Ensure your probe is a 3300 NSv series.
