摘要： A pressure sensor element for mounting in a connecting element comprises an isolator body with a laterally projecting membrane. The laterally projecting membrane covering an opening of a passage through which the pressure present at the surface of the membrane is conveyed to a pressure transducer element by means of a hydraulic fluid. In order to mount the pressure sensor element, it is secured in a mounting aperture of the connecting element. The projecting perimeter of the membrane is secured to the surface surrounding the mounting aperture of the connecting element by means of a continuous seam. A membrane type ring in combination with a conventional membrane may be substituted for the projecting membrane, wherein the membrane type ring covers the gap between the pressure sensor element and the adapter element.

摘要： A thin-film humidity sensor for measuring the absolute humidity having a base electrode, a moisture-sensitive dielectric layer and a top electrode is formed at the end face of an electrically insulating bushing body by the thin-film technique. The connecting conductors are led through the bushing body and terminate in contact areas which are ground plane and polished together with the end face of the bushing body. The metal layers forming the electrodes are so shaped on application, preferably by means of perforated masks, that they each cover the contact area of the associated connecting conductor and are electrically connected thereto. The bushing body is inserted into a sleeve of a highly alloyed nickel-molybdenum compound and connected thereto in pressure-resistant manner.

摘要： 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.
