ADTS 405F and ADTS 405R Performance expressed in example pressure units
Control Performance
Stability
The ADTS 405 provides stable pressure values at the outlet ports and continues to control
smoothly without oscillation into volumes of up to 17 litres (1,000 cubic inches) on Ps and a volume
of up to 10 litres (600 cubic inches) on Pt at rates up to 6000 ft/min. Lower volumes enable higher
rates of change to be achieved.
The following are the figures based on a 40 ppm of Ps full-scale or Qc full-scale over a bandwidth of
0.1 to 1.5 Hz and using RMS values. Below are shown the two Qc ranges used by the ADTS 405
