Embodiment Construction

[0056] figure 1 A pressure transducer according to the invention is shown. The housing 10 is installed on the process accessory 20. The display and control element 7 is installed on the housing 10, through the display and control element 7, the measurement result is displayed, and the operator can make various settings, such as setting a switch point or displaying the measurement result in different units. However, the present invention may also include a so-called transmitting device, which does not have a display or control element, and may alternatively adopt a high-level control unit to operate and configure parameters. A plug connector 8 is installed on one side of the housing 10, and the pressure transducer 1 is supplied with power through the plug connector 8, and the plug connector 8 also serves as an electronic interface. The generated measurement signal can be used for further processing in a high-level control unit, for example, in a PLC.

Abstract

The invention relates to a pressure-measuring transducer for the field of process measurement, which pressure-measuring transducer serves to measure the pressure of a process medium, comprising a metal process connection (20) for mechanically connecting to a container that contains the process medium and comprising a housing (10), which has a cylindrical housing segment composed of a sheet metal jacket (11), which is connected to the process connection (20). The connection between the housing (10) and the process connection (20) is at least impermeable to spray water in order to protect a pressure-measuring cell (2) and measuring and evaluating electronics (3) arranged in the interior of the housing (10). In order that the housing can be rotated in relation to the process connection and yet the pressure-measuring transducer can be simply produced, a segment (12) of the sheet metal jacket (11) according to the invention protrudes over a cylindrical segment of the process connection (20) in an overlap region (4) and the process connection (20) has a first annular groove (25) in the overlap region (4), into which first annular groove a deformation (15) produced by shaping the sheet metal jacket (11) protrudes, whereby the housing (10) can be rotated in relation to the process connection (20) but is fixed in an axial direction.

Description

Technical field [0001] The present invention relates to a pressure transducer according to the preamble of claim 1 and a method for producing such a pressure transducer, which is suitable for process measurement technology for measuring the pressure of a process medium. Background technique [0002] Pressure transducers of the type to be discussed have been known and used very early, for example, in many fields of process measurement technology for metrology process monitoring. These measuring devices are produced by the applicant, for example, devices that are put on the market under the name "PNxx". The measuring range is currently usually extended to 400 bar. [0003] In practical applications, this situation usually occurs after the measuring device is connected to the container, such as a water tank containing the medium to be measured, a pipe or the like that is not arranged in a preset direction. Then, for example, it is difficult to connect the cable to a plug connector p...
