​The IES200 is a high-precision embedded strain sensor for permanent structural monitoring of wind turbine rotor blades.

Manufactured on a GL-certified fiberglass laminate, the sensor is mechanically matched to the blade material and can be integrated directly into the composite structure during production or installed as a retrofit sensor patch.

It provides accurate long-term strain and temperature measurement over the entire service life of the blade — even under harsh environmental conditions.

Key features

• Strain measurement range: ±500 µm/m

• Bandwidth: 200 Hz

• Resolution: < 0.4 µm/m (16-bit)

• Output signal: 4–20 mA

• Temperature range: –100 °C to +100 °C

• Fatigue resistance: > 10⁸ load cycles

• Protection class: IP67

The IES200 is designed for reliable structural health monitoring, load measurement, fatigue analysis and lifetime extension of wind turbine rotor blades.
