Abstract : The invention relates to pressure transducers and, more particularly, to physiological pressure transducers of a volume-displacement, electromanometer type. The invention improves the frequency because of the Statham P23Gb pressure transducer and further teaches a manner of forming physiological pressure transducers capable of providing accurate data for microhemocirculatory studies. The principal discovery of the present invention is that markedly improved operation results by utilizing a pressure dome of a chamber volume which is minimized to the greatest degree possible consistent with other design criteria such as the size of the tube that couples the pressure dome to the circulatory system and the area of the diaphragm that forms part of the pressure dome.
