Data Analysis: Microlog's sophisticated data analysis capabilities

Time at Level

This analysis method sums the total time or the number of shaft revolutions accumulated at each of the 64 load or torque levels during the measurement period. The resulting histogram of torque or load vs. time provides valuable insights into operational conditions and helps determine correct conditions for laboratory testing.

Rainflow Counting

Ideal for structures subjected to random loading, rainflow counting analysis identifies the total number of fatigue cycles at 32 levels of mean and 64 levels of range. The output is a 3D matrix defining the number of closed fatigue cycles at specific mean vs. range locations, essential for fatigue analysis and design using linear cumulative damage theories like Miner’s Rule.

Data Capture​

Microlog captures and accurately time stamps up to 100 highest events per channel, each with 30% pre-trigger information. This type of data capture ensures that critical events are logged and stored securely, providing detailed insights into the highest stress occurrences.

Microlog is designed to meet the most demanding data acquisition needs. Its small size, robust performance, and advanced features make it an indispensable tool for engineers and researchers. Whether monitoring rotating machinery, performing failure analysis, or conducting fatigue testing, Microlog provides the precision and reliability required to gather actionable insights.

Typical Microlog Applications

Rotating Machinery Monitoring

Microlog is ideal for monitoring rotating machinery such as gearboxes, shafts, bearings, and couplings. By capturing detailed data on rotational speeds, vibrations, and loads, Microlog helps identify wear and tear, potential failure points, and areas needing maintenance. This proactive monitoring ensures the longevity and efficient operation of critical machinery components.

Stress Analysis

Microlog excels in stress analysis of dynamically loaded systems and structures. It accurately measures and logs stress data, enabling engineers to assess how various parts of a system respond to dynamic forces. This analysis is crucial for designing robust structures and ensuring they can withstand operational loads without failure.

Fatigue Life Estimation

Microlog provides vital data for estimating the fatigue life of products and components subjected to long-term stress. By analysing the data collected on stress cycles and load variations, engineers can predict the lifespan of materials and components, allowing for better design decisions and preventive maintenance strategies.

Failure Analysis

When mechanical failure occurs, Microlog assists in identifying the root causes. By logging detailed data leading up to and during the failure event, Microlog provides insights into stress levels, load conditions, and operational anomalies. This information is invaluable for diagnosing problems, improving design, and preventing future failures.
