Opis:: The novelty of this work is the analysis of accuracy measures and its visualization especially for the simultaneous two parameter measurements. The parameters of the resistance-to-voltage converters, i.e. different types of DC circuits with arbitrary variable resistive sensors (of relative resistance increments), and their accuracy measures are discussed. Transfer coefficients, limited error (and also standard uncertainty) as functions of relative increments of resistance are shown in broad range for different types of supply and sensor configuration of the circuit of initial 2D converters.

Opis:: This article presents a way of calibration of an unconventional two-current circuit, named 2J+2R, which consists of two current sources and two referential resistors connected to the circuit mass. This bridge was used to measure the beam deflection and the temperature increase simultaneously with the use of a pair of metal strain gauges. This paper contains theoretical and corrected (after calibration) processing characteristics of the measurement circuit. Calibration coefficients of both inputs, responsible for measurement of the measured values in the places where the strain gauges are attached, were calculated. Moreover, the standard combined and expanded uncertainties of both calibration coefficients were calculated and an uncertainty budget was made.

Tematy:: electronics
measurement circuits
Opis:: The two-voltage-output circuit called a double-current bridge is presented. A single DC current source is switched over and connected in turns to opposite arms of the four-element bridge circuit. The output voltages are dependent on the arm resistance increments and their values are given in absolute and relative units. The simplified signal conditioning formulas of strain and temperature simultaneous measurement of a cantilever beam are featured. The results achieved with the use of the circuit are also published.The accuracy measures (actual errors, limited errors and standard uncertainties) of the bridgetransfer functions are described.

Opis:: A four-terminal (4T) bridge-circuit, with two voltage outputs is presented. This circuit, named as double current bridge is supplied by two equal current sources connected in parallel to opposite arms (2J) or by one such source switched between those arms (2x1J). Two output voltages from bridge diagonals as functions of arm resistance increments in absolute and in relative units are given. Also the example of this bridge application is proposed. Signal conditioning formulas of two-parameter measurement on the example of strain and temperature are discussed in detail. Some results obtained with the use of this bridge-circuit are briefly described.

Opis:: The application of robust statistical methods to assess the precision (uncertainty) of the results of interlaboratory comparison tests is presented. The case, when these results may include outliers is considered. An usual rejection of such data reduces the reliability of evaluation, especially for small samples. The robust methods take into consideration all samples data including outliers. The use of the robust method Algorithm S is provided for estimating the precision of some measuring method tested in comparative studies in the group of accredited laboratories. Result obtained for simulated example is very close to the case with rejection outliers, but more reliable.

Opis:: There is proposed the application of an auxiliary quantity, homogeneous with the measured one, in the quality control of an object made with the use of measuring channel and processing and decision making module. The result of processing of this quantity in the measurement channel is applied for the additive and multiplicative correction of decision limits. This allows to reduce the impact of imperfect processing characteristics of measuring channel. The significant effectiveness of such correction, at different ratio of the components of processing error is presented. The influence of errors of forming auxiliary quantity is also considered.
