摘要：
A method for reducing the content of foreign molecules in gaseous or liquid form dissolved in a pressure transfer liquid of a pressure measuring transducer. A pressure receiving chamber is closed by an isolating diaphragm. A pressure measuring chamber is connected to the pressure receiving chamber, and a pressure sensor arranged in the pressure measuring chamber, in which the liquid serves to fill an inner space of the pressure measuring transducer formed by the pressure receiving chamber is provided. The pressure measuring chamber is connected therewith, and transfers an external pressure acting on the isolating diaphragm to the pressure sensor in measurement operation. The liquid is brought into contact with at least one adsorptive body, and foreign molecules dissolved in the liquid are bound to the adsorptive bodies by adsorption.
