Bently Nevada 990-08-50-03-CN Vibration Transmitter

Core Technical Specifications

• Manufacturer & Model: This is the Bently Nevada 990-08-50-03-CN vibration transmitter.
• Vibration Range: Its calibrated full-scale range is 0 to 8 mils peak-to-peak (0-200 μm pp).
• Operating Power: The unit requires a +12 to +35 Vdc power supply connected at its terminals.
• Output Signal: It generates a standard 4 to 20 mA two-wire current loop output.
• Signal Accuracy: The output accuracy is within ±1.5% across the entire measurement range.
• Frequency Response: It accurately captures vibrations from 5 Hz to 6,000 Hz.
• Cable System: It is configured for a total system length of 5.0 meters (16.4 feet).
• Loop Compliance: The transmitter can drive a loop resistance up to 1,000 Ω at 35 Vdc.
• Probe Installation: The connected proximity probe must be gapped 0.5 to 1.75 mm (20-55 mils) from the target.
