Overview

The Non-Intrusive Stress Measurment System is an alternative to strain gage instrumentation for measurement of blade dynamic stresses.

NSMS externally mounted sensors provide a flexible, cost effective, reliable alternative to strain gauges.

NSMS provides a complete system characterization of vibratory responses. The external nature of the sensors allows a more accurate representation of response than traditional strain gauges. Another advantage over strain gauges is the capability to perform long term health monitoring tests with minimal probe maintinance.
