Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Bestimmung und/oder Überwachung mindestens einer Prozessgröße eines Mediums. Bei dem Medium handelt es sich beispielsweise um eine Flüssigkeit, ein Gas, ein Schüttgut oder um eine Mischung daraus. Bei der Prozessgröße handelt es sich beispielsweise um die Feuchtigkeit, die Temperatur, die Dichte oder die Strömung des Mediums. Das Medium durchströmt dabei beispielsweise ein Rohr oder es befindet sich in einem Behälter.The invention relates to a device for determining and/or monitoring at least one process variable of a medium. The medium is, for example, a liquid, a gas, a bulk material or a mixture thereof. The process variable is, for example, the humidity, the temperature, the density or the flow of the medium. The medium flows through a pipe, for example, or it is located in a container.
In der Prozess- und Automatisierungstechnik ist eine Reihe von Messgeräten zur Messung oder Überwachung einzelner Prozessgrößen bekannt und in der Anwendung. Die Messung der Prozessgrößen dient u.a. dazu, um Prozesse zu überwachen und zu steuern. Da die Messgeräte den eigentlichen Prozess möglichst nicht stören sollen, und auch um die Kosten der Geräte und der Installation der Geräte zu reduzieren, ist es vorteilhaft, wenn zum einen die Messgeräte möglichst klein ausgeführt werden, und wenn zum anderen mehrere Prozessgrößen mit einer Messstelle, d.h. mit einem Gerät gemessen werden.A number of measuring devices for measuring or monitoring individual process variables are known and in use in process and automation technology. The measurement of process variables is used, among other things, to monitor and control processes. Since the measuring devices should not disturb the actual process as far as possible, and also in order to reduce the costs of the devices and the installation of the devices, it is advantageous if, on the one hand, the measuring devices are designed as small as possible and, on the other hand, if several process variables are connected to one measuring point, i.e. measured with one device.
