Pressure modules with compact design for flow measurements with Pitot tubes. |
FD A622 M1K
Pressure Modules for Differential Pressure
and Pitot Tubes Type
¡Ü Pressure
modules with compact design for flow
measurements with Pitot tubes.
¡Ü Fitting
for connecting hose between Pitot tube and pressure module.
¡Ü Pressure
modules can be directly plugged onto the measuring instruments.
¡Ü Socket
for connection of an additional temperature sensor for temperature compensation.
¡Ü Particularly
suitable for stationary wind velocity
measurements with continuously changing temperatures.
¢Ñ When attaching
the measuring module other input
sockets will be blocked. If the blocked input sockets need
to be used or if the module can be directly installed at
the measuring location, a pressure module type
FDA602M1K/M6 with extension cable ZA9060VKx (max.
5m) must be used. The temperature sensor must then
be connected via a second device input socket and
programmed as a compensation sensor.
