摘要： It is proposed to store spent nuclear fuel elements in welded-shut steel containers, which are filled with argon at about 2 atmospheres pressure. It is desirable to be able periodically to check the containers for leaks. The invention proposes to do this by providing apparatus for sensing the pressure within the container from outside the container. To achieve this, a pressure responsive bellows is mounted inside the container, such that changes in the container pressure move a metal plate attached to the bellows towards or away from a portion of the inside wall of the container. Then. if the container starts to develop a leak, the pressure will begin to drop, and the gap between the metal plate and the wall will change. This gap can be sensed from outside the container, by an ultrasonic pulse echo technique. Preferably. the bellows and plate are mounted within the head of the combined valve and lifting pintle by which the container is sealed.

摘要： A capacitive pressure sensor for an internal combustion engine is provided having a housing having a bottom surface, variable capacitor and circuitry. The variable capacitor is formed by a stationary electrode and an elastically bendable electrode. Pressure exerted on the bottom surface acts to bend the elastically bendable electrode. This bending alters the capacitance of the variable capacitor. The circuitry is configured to generate a signal based on the variable capacitance of the variable capacitor. This capacitance is representative of the pressure exerted on the bottom surface.
