Health & Usage Monitoring System

​HUMS is a sensor-based monitoring system that enables Condition-Based Maintenance by measuring the health and performance of mission-critical components in rotary wing aircraft. By continuously monitoring vibration at numerous points throughout the drivetrain, and pinpointing mechanical faults before they become catastrophic failures, HUMS provides actionable information that allows informed maintenance decisions. HUMS reduces maintenance costs of aircraft systems while increasing availability

With its reliable and rugged design, HUMS meets harsh environmental requirements of various Rotary Wing Aircrafts.
