📋 Tender Overview
Metrologists of the Voronezh CSM of Rosstandart have modernized the calibration vibration unit by introducing a new vibration stand into it.The installation is a working standard of the first category. According to Alexander Ivanov the leading engineer of the department for verification and testing of thermal measuring instruments of the Voronezh CSM as a result of the modernization the operating frequency range of vibration reproduction has increased from 0.2 to 20000 Hz the operating range of vibration acceleration is from 0.02 to 1000 m s2.Also within the framework of the modernization the function of connecting three-position sensors to the installation simultaneously along all axes determining the coefficient of transverse components and the harmonic coefficient was implemented. This made it possible to supplement the range of verified measuring instruments as well as to expand the scope of accreditation. There are no more than 10 reference standards in this design in Russia he added.Expanding the scope of accreditation including by improving the reference base that meets the needs of enterprises in the region is one of the program goals for the development of the center until 2023. Therefore metrologists constantly pay special attention to this area said Pavel Voronin head of the Voronezh CSM .
