Vibration Transmitter - 990-10-50-01-01 Bently Nevada

Bently Nevada 990-10-50-01-01 Vibration Transmitter

Key Product Specifications

• Manufacturer & Model: This is a genuine Bently Nevada 990-10-50-01-01 transmitter.
• Full-Scale Range: The device measures a range of 0 to 10 mils peak-to-peak (0-250 μm).
• System Configuration: It is calibrated for a 5.0-meter (16.4-foot) system with a 3300 NSv probe.
• Mounting & Certification: It features 35 mm DIN rail clips and carries CSA Division 2 agency approval.
• Electrical Input: The transmitter requires a +12 to +35 Vdc power supply at its terminals.
• Signal Output: It provides a standard 4 to 20 mA dc output in a two-wire setup.
• Output Accuracy: Loop accuracy is within ±1.5% of the full-scale range.
• Frequency Response: The unit captures vibrations from 5 Hz to 6,000 Hz (+0, -3 dB).

Installation and Wiring Details

• Mount the unit securely using its integrated 35 mm DIN rail clips.
• Connect one non-contacting 3300 NSv Proximity Probe and its extension cable.
• Ensure the probe gap to the target is between 0.5 and 1.75 mm (20-55 mils).
• The target must have a minimum diameter of 9.5 mm (0.375 inches).
• Keep the cable from the Proximitor Output (BNC) under 3 meters (10 feet).
• The total maximum loop resistance must not exceed 1,000 Ω at 35 Vdc.

Performance and Safety Features

• Current Limiting: The output is typically limited to 23 mA for protection.
• Fault Response: The output drops below 3.6 mA within 100 µs during a "NOT OK" condition.
• Adjustability: The unit has non-interacting external zero and span adjustments.
• Hazardous Area: This model is suitable for Non-Hazardous, Zone 2, or Division 2 locations.

Frequently Asked Questions (FAQ)

• Q: What makes the 01-01 model different?
  A: The 990-10-50-01-01 includes DIN rail mounting clips and CSA Division 2 hazardous area certification.
• Q: What power supply is recommended?
  A: A typical 28 Vdc power supply works well within the +12 to +35 Vdc input range.
• Q: How does it handle a sensor fault?
  A: During a fault ("NOT OK"), the 4-20 mA output drops to less than 3.6 mA within microseconds.
• Q: Is the zero adjustment independent?
  A> Yes, it features non-interacting adjustments, so changing the zero point does not affect the span.
• Q: What is the lead wire length limit?
  A: The maximum cable length from the transducer's BNC output is 3 meters (10 feet).
