DirectShear sensors are robust, high-bandwidth, high-resolution, micromachined wall shear stress sensors for subsonic and transonic applications.
A new low-profile package is now available as an option to acquire wall shear stress measurements in test sections and models where space is limited. This package was developed as a response to customer feedback and desire to measure wall shear stress in space restricted installations. The low-profile package dimensions are shown below:
- Sensor Head: 6 mm diameter, 9 mm length
- Sensor Base: 23 mm diameter, 4.3 mm length
- Total Length: 13.3 mm
Wall Shear Stress Sensors to Quantify Turbulent Boundary Layers
The measuring of wall shear stress is important to understand the thickness of a boundary layer, quantify drag, and predict when flow separation will occur. DirectShear sensors directly measure mean and fluctuating wall shear stress in a compact package with the key performance features necessary in a good wall shear stress sensor:
- Non-intrusive, ultra smooth sensing surface enables flush mounting
- Simultaneous mean and fluctuating shear stress measurements
- High bandwidth and dynamic range with varying model options for your application
- Small sensing element minimizes special averaging and temporal filtering
| Model | Shear Stress (Pa) | Bandwidth (kHz) | Sensitivity (mV/Pa) | Resolution (mPa) | Element Size |
|---|---|---|---|---|---|
| CS-0110 | 50 | 1.5 | 40 | 0.1 | 2mm x 0.4mm |
| CS-0610 | 100 | 2.5 | 10 | 1 | 2mm x 0.4mm |
| CS-0210 | 300 | 5 | 1 | 1 | 1mm x 0.2mm |
| CS-0310 | 1000 | 10 | 0.3 | 5 | 0.5mm x 0.15mm |
| CS-0410 | 5000 | 20 | 0.08 | 10 | 0.5mm x 0.15mm |
The DirectShear system represents the current state-of-the-art in wall shear stress measurement technology and is available in a wide variety of models and form factors for your application. Learn more on the DirectShear product page or contact IC2 at sales@thinkic2.com for more information.
