Flow Control and Wind Flow Pressure Mapping Now Possible

EAST HANOVER, NJ (USA) - Sensor Products Inc. unveils its Tactilus Surface Air Flow Sensor, containing a one-dimensional array of 16 pressure sensing elements. The sensor's capacitance-based design provides extreme sensitivity (down to a single drop of water!) for both positive and negative pressures. The thin construction allows significant flexing; mounting to curved surfaces, such as the leading edge of an airfoil, is easy. Multiple strips can be connected to the same interface, allowing hundreds of data points to be collected simultaneously. All Tactilus Air Flow systems are factory calibrated for high accuracy.

The TAF-1000 features a Tactilus pressure sensor mounted on a rigid rectangular plate. This product is ideal for pressure measurement applications involving a flat surface. Such high-sensitivity pressure data is valuable for many applications in aerodynamics, flow control, and fluid mechanics. The TAF-1500 features a Tactilus pressure sensor mounted on a rigid square plate. This configuration has been developed specially for pressure measurement in rheology and other fluid mechanics applications.

The TAF-2000 features a flexible Tactilus pressure sensor. This product is ideal for pressure measurement applications involving curved surfaces such as airfoils and pipes. The TAF-2000 finds many applications in aerodynamics, flow control, and fluid mechanics. Examples include wind tunnel testing and leak detection.
