Abstract:

Calibration of measuring instruments provides the confidence in measurements. It is the obligation of every laboratory to have its measuring equipment calibrated in regular intervals. This obligation means that the laboratory must send its equipment to the calibration laboratory every year or two depending on the calibration intervals. During this time the equipment is not available and this presents a financial burden to the laboratory of the customer. Since many of the modern instruments include some communication interfaces, it was made possible to create an Internet-enabled calibration sys

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

Abstract:

The basis of thermodynamic methods is that temperature accuracy should be high. When choosing thermal transducers, you should be guided by the following requirements for measuring equipment, the performance of which allows you to successfully use thermodynamic methods for diagnosing hydraulic machines in real working conditions: • high output signal level; • minimal inertia of heat exchangers; • high stability during operation; • minimum dimensions of primary heat exchangers; • sensitivity to vibration and shock; • sensitivity to external electromagnetic fields; • ability to use serial measuri

Abstract:

Calibration of measuring instruments is a critical aspect of ensuring the accuracy, reliability, and standardization of quality and safety assessments in grain laboratories. Precise measurements are essential for evaluating key agricultural product parameters, including moisture content, protein concentration, and contaminant levels, which directly influence market value, food safety, and regulatory compliance. Regular calibration of laboratory equipment is mandated by ISO/IEC 17025:2017, which establishes general requirements for the competence of testing and calibration laboratories. This st

Abstract:

The multi-degree of freedom laser scanning simulation platform used for simulating most on-line scanning and measuring equipments in manufacturing fields is beneficial to raise the design efficiency and save the design time of dedicated measurement equipment. The measuring model of the system is established by combining the D-H kinematics model with the linear structured light model in the article. The system model parameters are calibrated via various calibration methods. The results obtained have been analyzed by scanning criterion sphere in different angle and position. The experiments show

Abstract:

A method for calibrating a three-axis accelerometer unit of the navigation accuracy class is proposed. It is based on measuring the modulus of the gravity acceleration vector. The method provides the determination of twelve passport coefficients (including six separate values of non-orthogonality angles) of the linear metrological model of a stationary accelerometer unit under operating conditions. The developed method makes it possible to calculate the acceleration value with an acceptable error using non-precision equipment for calibration. The problem is solved by forming a system of linear
