PURPOSE:To make errors due to temperature change almost zero and to improve reliability, by forming pressure detecting chambers at the central part of a body, and forming a high pressure chamber and a low pressure chamber at both side- parts of the body. CONSTITUTION:A movable electrode 3 comprising a flat plate spring is provided at the central part of a body 2. Pressure detecting chambers 2a are formed at the central part of the body 2 by flanges 3a of the movable electrode 3. Flanges 7 and 8 are attached to both sides of the body 2. A high pressure chamber 9 and a low pressure chamber 10 are formed by the inner recess parts of the flanges 7 and 8 and the recess parts at the side surfaces of the body 2. In this differential pressure transmitting device, errors due to temperature change can be made almost zero, and reliability can be enhanced. |
