Display Unit For A Measuring Device For Processing And Automation Technology, And Measuring Device Having A Display Unit Of This Type

Abstract

The invention relates to a display unit for a measuring device for processing and automation technology, comprising a rectangular, but not square, graphic display (3), on which different measurement and/or parameter data of the measuring device (1) can be displayed, wherein the display (3) can be rotated in 90° steps relative to the display unit (2), such that the displayed measurement and/or parameter data can always be oriented horizontally regardless of a rotation of the display unit (2) in the vertical plane. The display (3) has at least two square sub-regions (4a, 4b) and these square sub-regions (4a, 4b) can be rotated independently of one another. The invention also relates to a measuring device for processing and automation technology comprising a display unit of this type.

6. The measuring device according to claim 5, wherein the two side lengths of the sub-regions (4a, 4b) together correspond to the width of the rectangular display (3).

7. The measuring device according to claim 5 or 6, wherein the display unit (2) is rigidly and non-rotatably connected to the measuring device (1).

8. The measuring device according to claim 5, wherein the display (3) has a side ratio of 16:9.

9. The measuring device according to claim 5, wherein the display unit (2) comprises an operating unit (5) in the form of at least one button, and the display (3) has a region (6) which is associated with the at least one button and displays the functionality thereof.

Description

[0014] In the schematic drawings:

[0015] FIG. 1 shows a measuring device for processing and automation technology comprising a display unit in a horizontal installation position, and

[0016] FIG. 2 shows the measuring device according to FIG. 1 in a vertical installation position.

[0017] In the following description of the preferred embodiments, the same reference numerals designate identical or comparable components.

[0018] FIG. 1 shows a measuring device 1 for processing and automation technology in the form of an electromagnetic flow meter (EMF), which in the present case is illustrated in a horizontal installation position. The display unit 2 is arranged offset from the actual measuring device 1 and comprises a rectangular, but not square, graphic display 3 based on LCDs or LEDs, on which different measurement and/or parameter data of the measuring device 1 are displayed. The display 3 consists substantially of two square sub-regions 4a, 4b, wherein current measured values in the form of flow rate and medium temperature are displayed in the first region 4a and parameter data or setting values such as switch points and the like are displayed in the second region 4b. The menu operation takes place either by means of operating buttons (not shown here) or also by means of touching the display surface 3, if the display is configured as a so-called touchscreen.

[0019] In FIG. 2, the measuring device 1 is illustrated in a vertical installation position, that is to say the entire measuring device 1 including the display unit 2 is now rotated by 90° relative to the horizontal installation position. In order to read the display 3 easily, the displayed measuring and parameter data should again be oriented horizontally. Therefore, the two square sub-regions 4a, 4b are in each case arranged rotated by 90° and one above the other. The special feature now is that the entire display 3 is not rotated, which would lead to an alteration of the width-height ratio, but that because of the sub-division into the two square sub-regions 4a, 4b, these sub-regions can be rotated independently of one another and because of the square configuration the width-height ratio is maintained.

[0020] Furthermore, FIG. 2 shows the display unit 2 with the aforementioned operating unit 5 in the form of two buttons as an exemplary embodiment. The two buttons 5 are provided in order also to be able to operate the measuring device 1 in situ. A narrow window inside the display 3 is associated with these buttons 5, and the functionalities of the buttons 5 are displayed in this window. In this case, the respective functionality may also be variable as a function of the menu position. The respective functionality is displayed by an element in the form of a symbol or an inscription. In the event of a rotation of the measuring device 1, the displayed elements rotate correspondingly, in order to be in the reading direction relative to the two square sub-regions 4a, 4b. The association with the buttons 5 and the position of the individual symbols remains unchanged.

[0021] As a result, the advantage of the invention also resides in the fact that the display unit 2 does not have to be rotatable with respect to the actual measuring device 1, which is frequently associated with high expenditure, for example for the sealing, in particular if the measuring device 1 is to be used in hygienic areas.
