ABSTRACT:
A pressure monitoring system in which pressure in a container causes a slide which extends out from the container, to be moved against a group of springs in cascade formation and which are screened from microwave radiation. The extent of such movement, which corresponds to changes in container pressure, is measured by means of a light transmitter and a receiver which cause light to be reflected off a reflective surface of the slide and then analyzed. Also disclosed is a process in which the heating of a container is controlled as a function of the differential quotient of pressure over time.
