Embodiment Construction

[0035] exist figure 1A section through a measuring device 1 according to the invention is shown in , wherein the device 1 is used in particular for measuring pH values ​​in the example shown. For this purpose, sensor element 2 is correspondingly designed as a glass body or alternatively made of plastic. A printed circuit board 3 adjoins the sensor element 12 , on which are located the components 4 necessary for the processing of the signals of the sensor element 2 or for its control.

[0036] The holding element 5 , in particular approximately designed as a cylindrical pin or rod, is provided for the casting process and for holding the printed circuit board 3 . Here, the printed circuit board 3 rests with its end (which is preferably likewise correspondingly designed for connection to the holding element 5 , for example thinned) in the recess 6 in the form of a groove in the end region of the holding element 5 . . The holding element 5 here also has the advantage that no f...

Abstract

A measuring device (1) for determining a process variable includes a sensor element (2) and a sleeve (10). The inner wall of the sleeve (10) is equipped with two recessed portions (11, 12), and a space in the area of the two recessed portions (11, 12) is surrounded by the sleeve (10). The invention aims at providing the measuring device which is especially for optimizing casting of a cavity, and the aim is realized in such a way that cross sections with different areas are formed by the two recessed portions (11, 12).

Description

technical field [0001] The invention relates to a measuring device for determining at least one process parameter with at least one sensor element for measuring the process parameter and with at least one sleeve at least partially surrounding the sensor element. In this case, the inner wall of the sleeve has at least two recesses and the sleeve encloses at least one space at least in the region of the at least two recesses. Background technique [0002] In modern process and automation technology, measuring devices are used for monitoring and determining process parameters, which generate measurement parameters that depend on the process parameter to be measured. The measured parameters are usually electrical signals available for evaluation and further processing. Process parameters are, for example, the flow rate, pH value, fill level or temperature of the medium. [0003] Such measuring devices of the prior art usually have at least a sensor element, which usually comes...
