Vibration Transmitters

Vibration Transmitters

Vibration transmitters are essential devices used to monitor and measure vibrations in machinery and equipment. They provide critical data to prevent equipment failures, ensure safe operation, and reduce downtime.

Purpose

• Continuous Monitoring: Provide ongoing monitoring of vibration levels, enabling early detection of potential failures.
• Predictive Maintenance: Track vibration trends to forecast maintenance needs, minimizing expensive repairs and unplanned outages.
• Equipment Protection: Help safeguard machinery by preventing damage caused by excessive vibrations.

How They Work

• Sensing Vibration: Sensors like accelerometers detect vibrations in the machinery.
• Signal Conversion: The sensor output is converted into an electrical signal, often in a 4-20 mA current loop, proportional to the vibration level.
• Signal Transmission: The converted signal is transmitted to a monitoring system (e.g., PLC, data logger, or computer) for analysis.

Key Features and Considerations

• Measurement Parameters: Vibration transmitters measure parameters such as:

  • Acceleration
  • Velocity
  • Displacement

• Frequency Range: Devices are designed to measure vibrations within specific frequency ranges for optimal performance.

• Output Signal: The common output signal is:

  • 4-20 mA current loop
  • Other output types may also be available depending on the model.

• Mounting: Proper mounting is essential for accurate measurement and reliable performance.

Applications

Vibration transmitters are widely used across industries, including:

• Manufacturing
• Power generation
• Oil and gas
• Pulp and paper
