Method for determining process variable of medium by electrochemical sensor, involves assigning reference half cell with temperature sensor, so that process variable is determined using temperatures detected by sensors

摘要

The method involves arranging reference half cell (18), active component (15) and temperature sensor (8), such that the reference half cell is assigned with temperature sensor (7) arranged in electronic circuit. The process variable is determined by higher-level unit using temperatures detected by temperature sensors. A sensor plug-in head (17) is provided at distal end of media of electrochemical sensor (1). The active component is selected from pH glass membrane, ion sensitive FET (ISFET), metal or non-metallic or metal oxide or carbon electrode. An independent claim is included for an electrochemical sensor electrode.
