Abstract:

The paper considers the designs of three-electrode differential capacitive sensors for use in displacement transducers. For the three simplest designs, the transformation functions are determined when sensors are included in the RC circuit of the maximum type and the Wien-Robinson measuring bridge circuit. The conversion functions are defined at a certain power frequency of the measuring circuit and an information output signal in the form of voltage.

Abstract:

Considering the scattering difference in resistance of the strain gauge which will cause the bridge unbalance, the designers of strain measurement instrument have to add bridge-balance circuit into the design of measuring bridge in order to eliminate the problem of a DC component output caused by the unbalance. Thus, in the design of the bridge-balance circuit, the selection of balance resistances is of great significance. In this paper, through calculation analysis of the balance bridge, we obtained a couple of ideal values of balance resistances and tested them by experiments. In this condit

Abstract:

Abstract Various measurements in wells are quite challenging due to the specific measurement conditions. There are some additional requirements for measurement systems, in particular, space restrictions. Therefore, measuring several parameters with a single sensor is rather important. The paper discusses a measurement system that allows measuring temperature and pressure with a single sensor – an SOS-based strain gauge pressure transducer with a bridge or half-bridge circuit. In this case, pressure and temperature measuring channels are calibrated individually, which creates another error comp

Abstract Any loss of power in converters is dissipated as heat in the components of the circuit. The article presents a new approach to measuring heat dissipation in a bridge power converter with hard switches using infrared thermography. Parallel measurements by thermocouples have been carried out. The experimental results are compared and used from the both cases.

Abstract:

This article presents an evaluation of the possibility of synthesis of a non-bridge system for measuring the dielectric loss coefficient on the basis of a simple bridge circuit. A rare feature of this bridge is that the circuit is brought to two equilibrium states, in which the modules of selected bridge voltages are equal. A favorable feature of the system is its maximum convergence, which greatly facilitates its balancing process. Equations describing the output signals of the bridge were derived, and then the structure of a non-bridge system was developed. An assessment of errors and system

Abstract:

Abstract Temperature measurement (thermometry) is indispensable in industrial operations, aiding engineers in monitoring and evaluating temperatures. This study focuses on the utilization of Platinum Resistance Temperature Detectors (Pt100 RTDs) for precise thermal measurements, operating within an input simulation range of 0-10 V and tailored for measuring temperatures from 10°C to 90°C in chemical processes. Using the Siemens PLC300 simulation system as the power supply, the experiment involved connecting a Pt100 RTD to a DC balance Wheatstone bridge to assess thermal conductivity characteri

Abstract:

Abstract. Especially in the case of measuring small forces, the use of conventional foil strain gauges is limited. The measurement uncertainty rises by force shunts and is due to the polymer foils used, as they are susceptible to moisture. Strain gauges in thin film technology present a potential solution to overcome these effects because of their direct and atomic contact with the measuring body, omitting an adhesive layer and the polymer foil. For force measurements up to 1 N, a suitable deformation element was developed by finite element (FE) analysis. This element is designed for an approx

Abstract:

At the moment, almost any electronic product incorporates measuring sensors for converting physical quantities. These devices produce a signal of measurement information in a form suitable for transmission and further conversion. As a rule, the output signal from the measurement sensors undergoes first preprocessing such as amplification, filtering, modulation, etc. After preprocessing the prepared signal, various architectures of analog‑to‑digital converters (ADC) are used. The choice of ADC depends on the parameters of the conversion signal and the dynamic characteristics of the sensors used

For example in the situation of measuring voltage dependence of low voltage capacitors and detecting high voltage bridge, the inductive voltage divider need to take two specific capacitors.

Abstract:

The article describes the process of calibrating strain gauge and measuring equipment. Modern machines have a complex design of the shapes of parts and assemblies. The loads acting on them often do not allow the determination of the stress state by modeling or calculation when creating these structurally complex machines. Therefore, conducting experimental studies using the strain gauge method is an extremely important task in real time. But for such a study, it is necessary to calibrate the strain gauges. Calibration must be performed to determine the functional relationship between the load
