P3403893-0351 Bently Nevada Vibration Transmitter

Bently Nevada P3403893-0351 2 Wire Vibration Transmitter

Key Technical Specifications

• Manufacturer & Model: Bently Nevada P3403893-0351 – 2 Wire Vibration Transmitter.
• Output Signal: Provides a standard 4-20 mA current loop output for seamless PLC or DCS integration.
• Power Supply: Loop-powered design accepts 12 to 35 VDC input voltage.
• Frequency Response: Covers a range from 5 Hz to 6,000 Hz (+0, 3 dB) for comprehensive vibration monitoring.
• Prox Out Linear Range: 1.4 mm (55 mils), beginning approximately 0.25 mm (10 mils) from the target surface.
• Incremental Scale Factor: 7.87 mV/µm (200 mV/mil) ±6.5% typical; worst case ±10% over the linear range.
• Temperature Stability: Scale factor remains within ±10% of 7.87 mV/µm across 0°C to +70°C (+32°F to +158°F).
• Output Impedance: Prox Out offers a 10 kΩ output impedance, calibrated for a 10 MΩ load.
• Minimum Target Size: Requires a target of at least 9.5 mm (0.375 inches) in diameter.
• Leadwire Length: Maximum cable distance from the Proximitor Sensor output (BNC connector) is 3 meters (10 feet).

Installation and Mounting Guidance

• Secure Mounting: Mount the transmitter casing directly to a rigid structural surface on the bearing housing. Use the proper mounting studs to ensure accurate vibration transmission.
• Surface Preparation: Ensure the mounting interface is free of paint, scale, or debris to maintain a clear mechanical impedance path.
• Cable Routing: Route the 2-wire shielded cable through grounded metallic conduit. Keep it away from high-voltage AC lines and variable frequency drives to avoid interference.
• Shield Grounding: Connect the cable shield to the instrumentation earth ground at the monitoring panel end only. Leave the shield ungrounded at the transmitter to prevent ground loops.
• Loop Voltage Check: Verify that the loop supply voltage remains between 12 VDC and 35 VDC at the transmitter terminals under maximum current load (20 mA).
