Single Sensor For Static and Dynamic Pressure

While looking at new products on GlobalSpec, I came across this sensor from Delta Metrics.  Delta Metrics (a subsidiary of tecsis DBA) has created a single sensor to measure both static and dynamic pressure simultaneously, reducing the complexity of implementing an airspeed sensor.  More information is available through Delta Metrics.
