Problems solved by technology
The disadvantage here is the relatively complex manufacturing process, since in particular the precision in the manufacture of these individual parts must meet high demands and must be machined with high precision in the joining and welding process, since the structural design of the device does not allow practically tolerance

Embodiment Construction
[0016] In the following description of the preferred embodiment, the same reference numerals designate the same or corresponding parts.
[0017] figure 1 Shown is an electronic pressure measuring device 100 for use in process measurement technology, which is manufactured and sold by the applicant under the name PNxxxx. The measuring device 100 essentially consists of a housing 2 which is divided into an upper part 3 and a lower part 4 . This lower part (also called process connection) comprises on the one hand a sensor unit in the form of a pressure measuring cell and on the other hand enables the mechanical connection of the measuring device 100 to the container or pipe containing the medium. Arranged in the upper part 3 is an electronics unit which is provided for the evaluation and processing of the measurement signal provided by the sensor unit, which can then be tapped via the shown plug connection and forwarded to, for example, a PLC .
[0018] Among other things, the...

The invention relates to a device for converting a pressure into an electric signal. The device has a first deformation body in the form of a first membrane, via which the pressure can be introduced into the device, and a second deformation body in the form of a second membrane, by means of the deflection of which the applied pressure can be converted into an electric signal. The device has a force transmitting means for transmitting pressure and / or tensile forces from the first deformation body to the second deformation body. Either the force transmitting means is designed as a separate part and the two membranes have a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to the respective membrane, or the force transmitting means is integrally formed with one of the two membranes and the corresponding other membrane has a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to said membrane.
Description
technical field [0001] The invention relates to a device for converting pressure into an electrical signal according to the preamble of claim 1 or 2 and to an electronic pressure measuring device comprising such a device. Background technique [0002] Such devices are generally based on the fact that the pressure induces a deformation of a deformable body provided for this purpose in the device, and this deformation is converted into an electrical signal. For example, bending beams for pure force measurements as well as membranes for pressure measurements can be provided. [0003] For certain applications, especially in process and food technology, a front-flush sensor or measuring device is advantageous, in which no medium can accumulate in the otherwise usual connection channel to the deformation body of the device. For this type of sensor, the deformation of the front-flush deformable body (eg, the front-flush membrane) is usually transferred via incompressible transfer ...
