Pitot tubes

Pitot Tubes fda6x2g.JPG (13981 bytes)

The air velocity measured by pitot tubes is calculated by the dynamic and the static pressure. Pitot tubes are suitable for applications with rough ambient conditions. They are available in versions of nickeled brass or stainless steel. Pitot tubes are connected via silicone hoses to a pressure cell and then to ALMEMOŽ instruments.

Measuring ranges	FD-A602-M6: ą 6800 Pa, differential pressure (2 to 90 m/s), measuring values in m/s, Pa FD-A602-M1: ą 2000 Pa, differential pressure (1 to 40 m/s), measuring values in m/s, Pa FD-A602-M1K: ą 1250 Pa, differential pressure (1 to 40 m/s), measuring values in m/s, Pa, position independant FD-A612-MR*: ą 1 bar, dynamic pressure measuring values in mbar
* using ALMEMOŽ instruments for exact measurements in m/s, the wind channel temperature can be entered for compensation.
With automatic temperature compensation for pitot tubes	FD-A622-M6: 2 to 98% m/s; measuring value:°C, m/s FD-A622-M1: 1 to 40% m/s; measuring value:°C, m/s
** the measuring modules with automatic temperature compensation are suitable for stationary measurements of the wind velocity at currently changing temperatures. All ALMEMOŽ NiCr-Ni temperatures sensors can be used. These measuring modules can only be used for measurements of the wind velocity, but not for pressure measurements.
