Abstract
PURPOSE:To reduce the application of an unnecessary stress to a pressure sensitive element due to a clamping torque of a screw or the like caused when a sensor is assembled, by giving a prescribes angle between the axial line of a bellows fitted to a shaking arm to which the pressure sensitive element is fixed, and that of a pipe for introducing a fluid into the bellows. CONSTITUTION:A pipe 9 for introducing a fluid pressure into a bellows 7 is bent at the right angle in a base 2. Because of this bending, a clamping force applied by the pipe 9 for introducing the fluid pressure onto the surface of a vessel 1 scarcely gives any stress directly to the bellows 7. therefore, no displacement occurs in a shaking arm 5. Accordingly, the nonuniformity in the clamping force of the pipe 9 causes little nonuniformity in the resistance or oscillation frequency of a pressure sensitive element 6 when no load is applied.
