Applications:

Shaft misalignment monitoring: The 128229-01 sensor is widely used to monitor shaft misalignment in rotating machinery. Misalignment can lead to excessive wear, vibration, and potentially catastrophic failure. By tracking the output of the sensor, misalignments can be detected early so that corrective action can be taken in time.

Bearing wear monitoring: The sensor can also be used to monitor bearing wear. As the bearing wears, the gap between the shaft and the bearing increases, which can be detected by the sensor. Early detection of bearing wear enables proactive maintenance and prevents bearing failure.

Vibration monitoring: The output of the sensor can be used to assess the vibration level of the rotating machinery. Excessive vibration can indicate a variety of problems, such as unbalance, loose parts, or damaged bearings. Monitoring vibration trends helps identify potential problems before they lead to major failures.

Application examples:

Protecting steam turbines: In steam turbines, the 128229-01 sensor plays a key role in preventing shaft pairs and bearing wear, which can lead to turbine inefficiency, damage and potential safety hazards.

Ensure generator reliability: Generators rely on sensors to monitor shaft misalignment and bearing wear to prevent generator vibration, noise and reduced efficiency.

Predictive motor maintenance: This sensor contributes to the predictive maintenance program of motors by providing early warning signals of non-neutralized bearing wear, timely maintenance and extended motor life.

Overall, the 128229-01 eddy current sensor and preamplifier module are important tools for reliable mechanical protection, especially in rotating machinery such as turbines, generators and motors.
