摘要:
The invention relates to a sensor (1) which is used to record measuring values in a melt (5). Said sensor can be inserted into a bore (2) of the wall (3) surrounding a cavity (4) which receives the melt (5), and is further developed so that it can be withdrawn from the wall (3) when the melt has substantially solidified without much effort and without damaging the sensor (1). The sensor is associated with at least one heating device (9).
摘要:
A method for controlling a melt-processing installation, wherein the installation has a melt-feed device, a filtering device, and a melt-processing device. Optionally, a melt pump can be used in addition to, or in lieu of, the melt-feed device. A maximum achievable rate of volume change per unit time of a volumetric feed of the melt-feed device and/or of the melt pump is determined, a maximum volume deviation value of the volumetric feed per unit time to the melt-processing device is determined, and a volume change in the filtering device between the melt-feed device and/or the melt pump and the melt-processing device is set such that a resulting rate of volume change of the filtering device is less than, equal to, or slightly larger than the maximum achievable rate of volume change of the melt-feed device and/or of the melt pump so that the maximum volume deviation value is not exceeded.
摘要:
Two methods for filtering a fluid, an apparatus and a filter apparatus for performing the method are described. The fluid to be filtered is passed through at least one filter, where the flow of fluid is throttled. At least one actual value of a working parameter of the fluid is measured; this actual value is compared with a predetermined set value and at least one actuating variable is generated as a function of at least one actual value-set deviation. The degree of throttling is then varied as a function of this actuating variable.
