Applications

Predictive Maintenance in Automotive Manufacturing

The ADI OtoSense SMS enables predictive maintenance by continuously monitoring motor vibration, temperature, and magnetic field. By analyzing these parameters using AI algorithms, the sensor can detect early signs of bearing wear, rotor imbalance, stator winding faults, and other anomalies. This proactive approach optimizes maintenance schedules, preventing unplanned downtime and reducing repair costs. Additionally, the SMS can identify operational inefficiencies, such as misalignment or overloading, leading to energy savings and improved overall equipment effectiveness (OEE).

Power Generation Industry Application

In power generation, reliability is paramount. The SMS monitors critical motors in turbines, pumps, and compressors, providing early warning of impending failures. By detecting anomalies such as bearing degradation, cavitation, or rotor eccentricity, the sensor helps prevent catastrophic equipment failures and associated blackouts. Furthermore, the SMS can optimize motor performance by identifying load imbalances, misalignment, and other factors affecting efficiency. This leads to reduced energy consumption and lower operating costs.

Paper Industry Application

The paper industry operates in a 24/7 environment where unplanned downtime is extremely costly. The SMS safeguards production by monitoring motors driving critical equipment like paper machines, pulp mixers, and pumps. By detecting issues like bearing wear, rotor imbalance, and cavitation, the sensor prevents unplanned shutdowns and reduces maintenance costs. Additionally, the SMS can optimize motor performance by identifying load variations and energy efficiency opportunities, contributing to overall process improvement and product quality.
