<p>A pressure transducer assembly comprises two plate members 11, 11a mounted face to face with a diaphragm 10 therebetween, the plate members 11, 11a being shaped so as to form respective chambers 14, 14a to which in use differential pressure is applied, each plate member 11, 11a carrying respective electrode means 16, 16a and including around its outer edge an annular portion 13, 13a. The plate members 11, 11a are formed of stiff resilient material such as steel, the inner edges 26, 26a of the annular portions 13, 13a abuting one another with the diaphragm 10 therebetween and being spaced from one another about their outer radii, and the two plate members 11, 11a are held together by means of a clamp ring 24 which surrounds the annular portions 13, 13a and flexes them so as to urge them towards one another to thereby grip the diaphragm 10 between the plate members 11, 11a. <IMAGE></p> |
