MEASURING TRANSDUCER FOR DETERMINING A MEASURED VARIABLE REPRESENTING A CONTENT OF H+ AND/OR OH- IONS IN A MEASURED MEDIUM

摘要

A measuring transducer, which is embodied to produce and output a measurement signal dependent on the content of W and/or OH⁻ ions present in a measured medium, wherein the measuring transducer has, in a region provided for contact with the measured medium, at least one polymer membrane selectively conducting W and/or OH⁻ ions. The polymer membrane can comprise an W ion conducting polymer and/or an OH⁻ ion conducting polymer.
