Product Description

DirectShear™ Sensors are robust, high-bandwidth, high-resolution, silicon-micromachined differential capacitive shear stress sensors for subsonic and transonic applications. This non-intrusive, design delivers an unprecedented degree of precision and accuracy for both mean and fluctuating wall shear-stress measurements.  This sensor system greatly extends the spatial and temporal resolution capabilities over existing devices, offering exceptional bandwidth and dynamic range.

Originally developed for NASA, the capacitive sensors are now commercially available and are ideal for precise skin friction measurements in wind tunnels.
