Method for determining and/or monitoring at least one process variable of a medium, a corresponding electrochemical sensor and a corresponding system |
摘要 |
A method for determining and/or monitoring at least one process variable of a medium by the utilization of at least of an electrochemical sensor comprising at least a first reference half cell and a second reference half cell, and comprising the method steps as follows: measuring a first electrical measured variable X1, cont with a first measuring period t1, meas and a first measuring interval t1, int with reference to the first reference half cell; measuring at least a second electrical measured variable X2, discont with a second measuring period t2, meas and a second measuring interval t2, int with reference to the second reference half cell; wherein the second measuring interval t2, int is greater than the first measuring interval t1, int; and determining the at least one process variable from at least one electrical measured variable X1, cont or X2, discont. Furthermore, the invention relates to an electrochemical sensor and to a system. |

1. A method for determining and/or monitoring at least one process variable of a medium by means of at least one electrochemical sensor comprising at least a first reference half cell and a second reference half cell, and comprising the steps of:
measuring a first electrical measured variable X1, cont with a first measuring period t1, meas and a first measuring interval t1, int with reference to the first reference half cell, measuring at least a second electrical measured variable X2, discont with a second measuring period t2, meas and a second measuring interval t2, int, taking into consideration the second reference half cell, wherein the second measuring interval t2, int is greater than the first measuring interval t1, int; and determining the at least one process variable from the at least one electrical measured variable X1, cont or X2, discont. |
