Design and Construction of Metrological Equipment for Torque Sensors with a Carbon-based Measuring Arm

Abstract

The paper presents a comprehensive design of metrological equipment for the verification and calibration of torque sensors, detailing the process from conception to construction and highlighting the specificities of its structural design to meet metrological requirements. The measuring device's functionality and individual structural components are described, along with the methodology for creating a complete product. The paper addresses the crucial issue of measurement uncertainty and the necessary accuracy, achieved through the construction of a special measuring arm made of carbon material. FEM analyses of the carbon arm are presented and compared against required metrological accuracies. Furthermore, we discuss the different properties of various carbon structures in Pre-preg materials used in designing the measuring arm and presents the results of measurements of such carbon materials. This paper provides a comprehensive insight into the design and construction of metrological equipment for torque sensors with a focus on its compliance with metrological requirements. The proposed device aims to establish the foundations of primary metrology of torque in Slovakia and has potential applications in a wide range of industries.
