Pneumatic Pressure Connections

ADTS 405 rack-mounted unit
Static (Ps) ............................................................................................................................ AN-6 37° flare
Pitot (Pt) ............................................................................................................................ AN-4 37° flare
Pressure supply ....................................................................................................................... AN-4 37° flare
Vacuum supply ........................................................................................................................ AN-6 37° flare
Connect pressure and vacuum supplies to the rear panel PRESSURE and VACUUM
connectors. The pressure supply should be clean, dry gas, nitrogen or air refer to the
specification.
Connect the Unit Under Test (UUT) to either the front panel or optional rear panel Ps
(static) and Pt (pitot) output connectors.
Note: Blanking caps must be fitted on unused front or rear outputs.
ADTS 405F flight line
Static (Ps) ............................................................................................................................ AN-6 37° flare
Pitot (Pt) ............................................................................................................................ AN-4 37° flare
Pressure supply ....................................................................................................................... AN-4 37° flare
Vacuum supply ........................................................................................................................ AN-6 37° flare
Auxiliary vacuum supply ..................................................................................................... AN-4 37° flare
In normal operation make sure that the correct blanking caps are fitted to the external
connectors.
The external pressure and vacuum connections are used when an external pump unit
supplies the pressure and vacuum. This may increase the maximum achievable rates
of change when connected to large volume systems.
The auxiliary vacuum, AUX VACUUM, can be used to supply the suction-type static
adaptors and provides a nominal 100 mbar (3 inHg) absolute vacuum. When not in
use, a blanking cap must be fitted.
Note: A leak of this blanking cap affects the performance of the ADTS 405F.
