DYNAMIC MODELS OF ION-SELECTIVE ELECTRODES WITH THEIR ELECTRONIC INTERFACE
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 4
Abstract
Dynamic models of an ion-selective electrode are analysed in this article taking into account the independence of values of its dynamic parameters from the value and direction of activity change. Unfortunately, a complicated mathematical representation of a new model makes the model difficult to be applied in practice. Therefore, some simplifications are made constructing two semi-empirical models: 1) a model with the k parameter and 2) a model basing on two other models well-known from the literature. Verifications of the new models have been performed using the measuring set-up built in the Division of Measurement Systems at the Silesian University of Technology. Obtained results proved that the model with the k parameter completely fulfils the goal of the article − its dynamic parameters are dependent on the slightest degree of the kind of activity step.

NUMERICAL ANALYSYS OF THE INFLUENCE OF ASYMMETRIC DEFORMATION OF THE VELOCITY FIELD ON METROLOGICAL PROPERTIES OF THE ORIFICE
A change of the stream direction during a flow through a single elbow or their system causes asymmetric deformation of the velocity field. If two elbows are located in various planes, also a stream swirl can occur. The i...
