Abstract:
The article presents current trends in impedance metrology of the highest accuracy. Attention was paid to digital non-quantum impedance bridges, which have been developed in many European National Metrology Institutes over the last decade. Particular attention in the article was devoted to the digital impedance bridge currently being developed at the Central Office of Measures in Warsaw. The conceptual diagram, system implementation and the progress of work related to the development of this bridge and its implementation in the near future into the national measurement system are presented as

Abstract Cardiac Radiofrequency (RF) ablation is a commonly used clinical procedure for treating many cardiac arrhythmias. However, the efficacy of RF ablation may be limited by two factors: small ventricular lesions and impedance rise, leading to coagulum formation and desiccation of tissue. In this paper, a high frequency (HF) energy ablation system operating at 27.12 MHz based on an automated load matching system was developed. A HF energy matched probe associated to the automated impedance matching device ensures optimal transfer of the energy to the load. The aim of this study was to eval

In the currently used primary impedance measuring systems, there is a need to compare standards with ratios different from 1:1, e.g., in order to transfer the value to multiples or submultiples of the basic quantity. Unfortunately, the commercial PXI sampling systems used to measure the voltage ratio in the impedance bridge, although they provide adequate resolution, show a considerable non-linearity of the measurement. This leads to significant error of the impedance ratio measurement. Experimental studies of commercial PXI digitizers used in primary impedance metrology are presented in the p

Abstract International comparisons of relative humidity scales at the highest level are often challenging because of significant drift of the impedance-based transfer standard, which reduces the accuracy of comparison. Comparisons that are shorter or have fewer participants may be less affected by drift, but ultimately require more inter-linking with their inherent irreproducibility to compare all scales internationally.
