The study of the influence of temperature effects on the output signal of the eddy-current transducer using simulation modeling

A model of eddy-current transducer is constructed taking into account the influence of the main destabilizing factor-temperature. The effect of temperature on the two-element and three-element (synthesized) equivalent circuit of the eddy current transducer is estimated. The possibilities of independent separate measurement of informative and non-informative parameters of the equivalent circuit are considered. Circuit solution of eliminating a non-informative parameter using a quasi-differential circuit made it possible to significantly reduce by 37 % the additional temperature error. In addition to the effect of temperature, the effect of non-compensation of the initial inductance on the output signal of the eddy current transducer is estimated.

Keywords: eddy current transducer, models.

Compensation of the angular etching of silicon structures during etching in a solution of potassium hydroxide

Methods for compensating for the angular misalignment of the outer corners of silicon micromechanical structures during etching in potassium hydroxide solution KOH are considered. Many existing models do not take into account the topological features of the structures being formed, in particular the distance from the compensating elements to the neighboring elements or to the edge of the mask. The possibility of compensating the angular misalignment on the basis of compensators of complex shape is shown. Their use makes it possible to increase the possible depth of etching while preserving the geometric dimensions of the compensators in comparison with the known ones.

Keywords: volume microprocessing of silicon, micromechanical sensors, MEMS, anisotropic etching, compensating elements.

Multiversion technology of increasing the reliability of production-ecological monitoring measurable parameters

The paper reviews the problem of industrial and environmental monitoring of thermal power plants impact on the environment. The paper gives regulating documents helping to solve the task. The problem of obtaining reliable values for multipoint measurement of parameters of industrial and environmental monitoring is described. The authors propose the solution to solve the problem by using multiversion decision models. The implementation of the simulation environment for the study of the proposed approach is considered. The results obtained by using the developed simulation environment are analyzed, which makes it possible to conclude that multi-diversion technology effectively supports multipoint measurements of environmental monitoring parameters, moreover it not only solves the problem of obtaining a parameter value from a variety of measurements, but also increases the reliability of the obtained data.

Keywords: measurement, parameter, monitoring, multiversion technology, reliability.
