AN IMPROVED INDICATOR for MEASURING STATIC and DYNAMIC PRESSURES 440206

THE principle of operation and the mechanical design of an improved indicator for measuring static and dynamic pressures are discussed in this paper.
The condenser type of indicator was selected by the authors for engine work because it lends itself to an exceptionally compact and sturdy construction, it is easily serviced, it has a high natural frequency, and it is relatively insensitive to shock and vibration.
This type of indicator also does not require mechanical linkage between the pressure diaphragm and the electrically sensitive element.
