Abstract
A pressure mediator includes a base body; a divider diaphragm system having a first divider diaphragm and a second divider diaphragm, between which an intermediate chamber is enclosed in pressuretight fashion, in which the first surface of the first divider diaphragm, remote from the intermediate chamber, can be acted upon by the pressure prevailing in the first medium, and the first surface of the second divider diaphragm, remote from the intermediate chamber, is oriented toward the base body and is secured by its peripheral region to the base body, forming a pressure chamber between the base body and the second divider diaphragm, and the pressure chamber can be filled with the second medium and has a pressure chamber opening, through which the pressure can be transmitted by means of the second medium, and an exertion of pressure of the first divider diaphragm can also be transmitted to the second divider diaphragm via the intermediate volume; and having a sensor, for monitoring a property of the intermediate chamber, characterized in that the pressure mediator furthermore has a diaphragm module, which includes a pressure chamber, to which the first divider diaphragm is secured by…
