Bently Nevada P3403893-0351 Vibration Transmitter

Product Overview

The Bently Nevada P3403893-0351 is a legacy, high-precision industrial vibration transmitter designed for continuous machinery protection. Operating on a simple 2-wire loop-powered principle, it converts mechanical vibration into a standard 4-20 mA analog signal. 

Technical Specifications

• Part Number: P3403893-0351

• Product Type: Vibration Transmitter (Velocity or Acceleration dependent)

• Wiring Scheme: 2-Wire, Loop-Powered

• Output Signal: 4-20 mA (Proportional to vibration level)

• Input Voltage: 12-35 VDC

• Weight: 1.15 lbs (Approx. 0.52 kg)

• Connection: Standard industrial threaded mount

• Status: Legacy / Discontinued (Maintenance-ready via secondary markets)

Key Features & Engineering Advantages

• Simplified Integration: The 4-20 mA output allows vibration data to be treated like any other process variable (e.g., pressure or temperature), removing the complexity of high-frequency waveform analysis for basic monitoring.

• Rugged Construction: Built to withstand the harsh conditions of industrial plants, including high moisture, oil mist, and constant mechanical shock.

• Loop-Powered Efficiency: By utilizing a 2-wire configuration, it requires significantly less cabling than 3-wire or 4-wire sensors, reducing installation and maintenance costs.

• Broad Compatibility: Operating on a standard 24V DC nominal power supply (within the 12-35V range), it is compatible with almost all industrial control system analog input cards.

• Cost-Effective Protection: Ideal for "General Purpose" machines such as small pumps, fans, and blowers where a full Bently Nevada 3500 rack system would be over-engineered.
