Abstract: The invention relates to a method in autoclaves, the autoclave being divided into imaginary areas, the areas being heated by the feeding of steam into the areas in order to heat goods which have been placed in the autoclave so that it reaches sterilising temperature, whereby the feeding of heat between the areas is controlled. Such control is effected by successive registration of the temperatures in the areas and when the temperatures differ between the areas, the feeding of steam to the area which temporarily has a higher temperature is ceased, and as soon as the temperature in the adjacent area has passed the last mentioned temperature, the feeding of steam to that same area is resumed. In a device for the carrying out of the method, a temperature meter is arranged in each area.

Abstract: A method of compensating for differences of temperature, in a pressure sensor of the kind wherein a pressure is sensed by use of a diaphragm connected in a Wheatstone bridge circuit. First measurement points of offset output signals emanating from the bridge in the pressure sensor at a number of temperature levels are plotted in a first graph indicating the voltage as a function of the resulting resistance of the bridge, whereupon adjacent measurement points are interconnected by straight lines and calculation is effected through interpolation between the measurement points. The sensitivity of the pressure sensor such as voltage/pressure unit, is determined in a corresponding manner at different temperature levels by plotting second measurement points in a second graph indicating the sensitivity as a function of the resulting resistance in a similar way the last mentioned measurement points are interconnected by straight lines, and calculation is effected through interpolation between the measurement points.
