Cloud-based tachometer systems can store large amounts of data and provide real-time analytics, improving decision-making and optimizing maintenance schedules. Research from the Cloud Security Alliance (CSA) on February 5, 2023, suggests that cloud computing enhances the scalability and reliability of tachometer applications.

10.9 Predictive Maintenance

Predictive maintenance is becoming more sophisticated, using tachometer data and other information to predict equipment failures and optimize maintenance schedules. Predictive maintenance programs can reduce downtime, lower maintenance costs, and improve equipment reliability. A study by the Predictive Maintenance Association (PMA) on January 10,
