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.
