A method for determining the wear dependent its residual tool life of an electrochemical measuring sensor

摘要

A method for determining the wear dependent its residual tool life of an electrochemical measuring sensor with the following process steps:– Determination of a for the function or the wear of the sensor relevant parameter (np, st) as a basis for the its residual tool life - determining,– Definition of at least one limit value (np_g, St_g) for this parameter (np, st), and– repeated determination of the value (np_i, St_i) this parameter (np, st),characterized by the following process steps:– Extrapolation of the value development of this parameter (np, st) of these previously determined parameters - values (np_i, St_i), and– Determination of the time interval (t representing its residual tool life_Ri) between the extrapolation and the limit value is exceeded (np_g, St_g) by the extrapolated parameters - value.
