Abstract

PURPOSE:To obtain a pressure detector which has one pressure introduction part by transducing pressure into displacement through a connecting rod which connects with a couple of pressure receiving elements differing in effective area. CONSTITUTION:Movable ends of bellows 11 and 10 of pressure detecting elements which are connected fixedly to a pressure receiving unit 31, welded to a pressure detector 1, each at the other end and differ in effective area are welded to a connecting rod 7. The bellows 10 are applied the atmospheric pressure througha hole 35, and the bellows 11 through a disphragm 31 for temperature compensation and an uncompressed fluid of silicone, etc., so that the rod 7 is displaced according to high pressure applied through the pressure introduction opening 34 of the unit 31. Then, variations in capacity corresponding to pressure transduced by the displacement are detected by a displacement transducing detecting means 19. Therefore, only one pressure introduction part is required and the easily manufactured pressure detector of simple constitution is realized.
