COMPARISON OF FURNACE TEMPERATURE AND INCIDENT HEAT FLUX IN WALL AND FLOOR FURNACES CONTROLLED BY SIX DIFFERENT TEMPERATURE SENSORS

摘要

This paper presents and discusses the performance of six different types of temperature measuringsensors namely: the ASTM E119 shielded thermocouples, ISO 834 plate thermometers, directionalflame thermometers, bare-bead thermocouples, Inconel grounded and ungrounded thermocouples inwall and floor fire resistance furnaces. The Inconel grounded and ungrounded thermocouple providedcomparable results to those of the bear-bead thermocouples where a fast response time is preferable.They also provided a faster response time than the plate thermometers. Because of their durability andfast response time either could be a good potential sensor for use in fire resistance standard testfurnaces.
