Problems solved by technology

This can lead to a large time delay between the creation of the leak and the detection of the doping caused by the leak, which delay depends on the depth of the blind hole and the installation details of the pressure transmitter

Embodiment Construction

[0029] figure 1 The pressure transmitter shown comprises a platform 1 having a preferably substantially cylindrical symmetrical structure. The separation membrane 2 is fixed at its edge 21 on the platform front side 13 so that a pressure chamber 11 is formed between the separation membrane 2 and the platform. The front side 13 of the platform 1 can have a film base in the usual manner, against which the separating film 2 is pressed when overloaded.

[0030] The pressure chamber 11 has an opening 12 for transmitting the pressure prevailing in the pressure chamber. The opening 12 is preferably configured as a capillary. In this preferred embodiment, the opening 12 extends to a pressure fitting 14, preferably of generally cylindrical or axisymmetrical recessed shape, which is flanked by the platform 1 opposite the contained separation membrane 2 .

[0031] In a preferred embodiment, the connection of the pressure delivery line 4 takes place via a connection adapter 3 in which ...

Abstract

A pressure transmitter for transferring a pressure from a pressure prevailing in a first medium onto a second medium includes a pressure chamber between a platform and a dividing membrane, wherein the pressure chamber is fillable with the second medium and has a pressure chamber opening, through which the pressure can be transmitted by means of the second medium to a pressure measurement cell. The pressure transmitter includes a sensor for monitoring a material property of the second medium, preferably a conductivity sensor with at least one electrode, which sensor can detect contaminants in the second medium from the first medium following a rupture of the dividing membrane on the basis of changes in the monitored material property. The sensor is in flow connection with the pressure chamber by way of the pressure chamber opening.

Description

technical field [0001] The invention relates to a pressure transmitter, or interposer, with a diaphragm seal for transmitting the pressure prevailing in a first medium to a second medium. [0002] More precisely, the invention relates to a pressure transmitter having the following components: [0003] --platform; [0004] - a separating or spaced film or membrane fixed at its edge to the platform, wherein a first surface of the separating film facing away from the platform is capable of contacting the first medium and a second surface of the separating film facing the platform the surface and the platform form a pressure chamber capable of being filled with a second medium, wherein the pressure chamber has a pressure chamber opening through which pressure can be transmitted by the second medium; and [0005] - a sensor for monitoring the properties of the medium contained in the cavity. Background technique [0006] Devices of this type are used, among other things, for p...
