The triple point of water serves to define the kelvin, unit thermodynamic temperature, in International System Units (SI). Furthermore, it is most important fixed Temperature Scale 1990 (ITS-90). Any uncertainty realization contributes directly measurement over wide temperature range from 13.8033 K 1234.93 K. Consultative Committee for Thermometry (CCT) decided at its 21st meeting 2001 carry out a comparison cells and charged BIPM with organization. Water 20 national metrology institutes...
The basic working tool in measurement uncertainty analysis, as advocated recent discussions related to the possible revision of Guide expression (GUM), and particular by its Supplements, is state-of-knowledge distribution about quantity derived based on currently available information. GUM framework (GUF) provides a method for assessing law propagation characterization output Gaussian or scaled shifted t-distribution. Supplement 1 concerned with probability distributions through model basis...
Abstract Evaluation of uncertainties the temperature measurement by standard platinum resistance thermometer calibrated at defining fixed points according to ITS-90 is a problem that can be solved in different ways. The paper presents procedure based on propagation distributions using Monte Carlo method. employs generation pseudo-random numbers for input variables resistances points, supposing multivariate Gaussian distribution quantities. This allows taking into account correlations among...
This is a summary of the Consultative Committee for Thermometry (CCT) Key Comparison CCT-K3, i.e. comparison realizations fixed points International Temperature Scale 1990 (ITS-90) over range 83.8058 K to 933.473 K. The differences in various this ITS-90 and uncertainties those are given fifteen standards laboratories participating comparison.
Abstract This paper focuses on the problematic of intraocular pressure (IOP) measurements, performed by non-invasive methods. More specifically, devices that are connected with presented finding non-contact tonometers use concentrated air stream and optical sensors to determine IOP within a human’s eye. The analyzes various influential factors have an effect determination values originating from patients themselves tonometer devices. furthermore elaborates lack independent methods...
Abstract Au/Pt thermocouples are considered as an alternative to High Temperature Platinum Resistance Thermometers and one of the prime candidates replace them interpolating instrument International Scale 1990 (ITS-90) in temperature range between about 660 °C 962 °C. This work presents results investigation two that used exclusively quartz glass (SiO2) insulation material. Measurements fixed points Zn, Al, Ag were realized on these well with interchanged inner made high purity aluminium...
Temperature measurements are one of the key factors in many industrial applications that directly affect quality, effectiveness and safety manufacturing processes. In these temperature realized by thermocouples. Accuracy thermocouples affects quality final product their durability determines margins required. One significant effects precision is short long term stability voltage output. This issue occurs every type caused multiple factors. general Seebeck coefficient which a material...
Abstract Atmospheric air temperature values are fundamental in meteorology and climate studies. To achieve high accuracy the measurements, features, characteristics performances of instruments importance. This study focuses on most commonly used sensors within automatic weather stations, with a specific focus evaluating self‐heating effect. Self‐heating stations originates not only from sensor itself but also electrical components housed together within. effect introduces extra heating...
Abstract The paper deals with the influence of various biomechanical parameters on intraocular pressure (IOP). IOP is a very important factor in more accurate diagnosis and better management glaucoma. To get realistic value measurement methodology must reflect patient’s individual biometric parameters, for example age, sex, race, properties cornea, etc. Many measuring methods are based applanation cornea during its loading by device - tonometers. These tonometers apply Imbert – Fick law [1],...
The propagation of uncertainties, when the International Temperature Scale 1990 (ITS-90) is used by a standard platinum resistance thermometer (SPRT) calibrated at defining fixed points (DFP), can be solved applying several approaches. article presents an analysis contribution covariance between resistances SPRT (DFP). Its effect on temperature measured demonstrated using real calibration data.
This paper is going to focus on the problematic of intra ocular pressure (IOP) measurements, performed by non-invasive methods. More specifically devices that will be subject investigation are non-contact tonometers use a concentrated air stream and optical sensors determine IOP within human's eye. The deals with issues connected this measurement method, presenting standard capable calibrate these traceability basic SI unit uncertainty. By introducing an independent traceable calibration...
<p><strong>Purpose:</strong> The paper deals with the legal metrology that is principally responsible for assuring uniformity and correctness of measurements presents results scientific research work in cross-disciplinary fields. design new measuring system verification radar level gauges. <br /><strong>Methodology/Approach:</strong> requirements on performing instruments are changed significantly, especially requirement reducing time necessary putting out...
In this paper, a complete design of discrete low-pass, high-pass, band-pass, band-stop filters based on an analog model is performed. This approach combines the advantages designing continuous-time filters, which are real electrical circuits, whit digital in form program running infinite loop. Unlike standard filter directly discrete-time, case, designed as and subsequently transformed into while maintaining all properties.
The article deals with types of artificial corneal material designed for the eye model, which is to calibrate optical tonometers. This focused on comparison suitable materials cornea, measurement and evaluation data selected contact non-contact It sets partial conclusions calibration tonometers in ophthalmological practice from point view used.
