990-10-50-03-00 Vibration Transmitter Bently Nevada

Bently Nevada 990-10-50-03-00 Vibration Transmitter

Core Technical Specifications

• Brand & Model: This unit is the Bently Nevada 990-10-50-03-00 vibration transmitter.
• Measurement Range: It provides a full-scale measurement range of 0 to 10 mils peak-to-peak (0-250 μm pp).
• Output Signal: The device delivers a linear 4 to 20 mA current signal in a two-wire configuration.
• Output Accuracy: The 4-20 mA loop maintains an accuracy of within ±1.5% over the specified range.
• Frequency Response: It accurately responds to vibration from 5 Hz to 6,000 Hz.
• Power Supply: Operation requires a +12 to +35 Vdc power input at the terminals.
• System Length: The transmitter is configured for a 5.0 meter (16.4 ft) extension cable system.
• Max Loop Resistance: It can drive a loop resistance up to 1,000 Ω at 35 Vdc, including cable.
• Probe Gap: For proper operation, the probe must be gapped 0.5 to 1.75 mm (20-55 mils) from the target.

Installation & Application Details

• Mounting Option: This model includes DIN rail clips and screws (Option 03) for flexible panel or rail mounting.
• Hazardous Area Rating: The "00" option indicates no specific agency approvals; it is for use in standard industrial areas.
• Target Requirements: The minimum target diameter for reliable measurement is 9.5 mm (0.375 inches).
• Diagnostic Output: For test equipment, the BNC "PROX OUT" has a maximum cable distance of 3 meters (10 feet).
• Fault Response: In a "NOT OK" state, the output current drops below 3.6 mA within 100 microseconds.

Frequently Asked Questions (FAQ)

• Q: What is the key difference between mounting options 01 and 03?
  A: Option 01 includes only DIN rail clips, while Option 03 provides both DIN rail clips and screws for added mounting versatility.
• Q: Can I use this transmitter with a 7-meter cable system?
  A: No, the "50" option specifies calibration for a 5.0-meter system. Using a 7-meter cable requires the corresponding "70" model variant.
• Q: What does a "Not OK" condition indicate?
  A: It signals a problem like a faulty probe or broken connection, causing the output to drop below 3.6 mA to alert the control system.
• Q: Is external adjustment available for this transmitter?
  A: Yes, the Bently Nevada 990-10-50-03-00 features accessible non-interacting zero and span adjustments for calibration.
• Q: Do you provide the matching proximity probe?
  A: The transmitter requires a separate 3300 NSv Proximity Probe. We can typically supply the compatible probe as part of a complete system.
