Static Pressure Heads SPH10/20

For minimizing wind induced error.

Variations due to strong and gusty wind can be overcome by using a static pressure head to ‘filter out’ the effect of dynamic pressure. The Vaisala Static Pressure Head Series SPH10/20 are designed to minimize the errors caused by wind. 

The wind tunnel tested structure is both horizontally and vertically symmetrical. This design ensures reliable barometric pressure measurements in all weather.
