Transcripción del resumen del autor. Defining a methodology for measuring temperature in fire resistance furnaces is a challenge. This paper presents and discusses the performance of six different types of temperature sensors in wall and floor fire resistance furnaces namely: the ASTM E119 shielded thermocouples, ISO 834 plate thermometers, directional flame thermometers, bare-bead thermocouples, Inconel grounded and ungrounded sheathed thermocouples. The Inconel grounded and ungrounded sheathed thermocouples provided comparable results to those of the bear-bead thermocouples and are most suitable when a fast response time is desirable. Because of the fast response time and good durability, grounded and ungrounded junction thermocouples are well-suited for use in controlling the temperature in fire resistance standard test furnaces. The predicted and measured incident heat flux in furnaces controlled by either the bare-bead or grounded and ungrounded sheathed thermocouples are in good agreement.
