Ověření vlastností betonových směsí ve vysokých teplotách pomocí optovláknových DTS systémů

Abstract

DTS (Temperature Distribution System) is a system using optical fiber as a temperature sensor. DTS evaluate the optical signal passing through the fiber and after processing provides information on the temperature profile along the fiber.

In the first part of the work deals with the thermo-physical and thermo-technical properties of concrete and in the second part about the problems of measuring temperature with DTS. It is complemented by experimental part, where was verified possibility of measurement using optical fibers, embedded in concrete, at high temperatures.
