- Abstract
- This report describes the design, development and evaluation of a probe system with which instantaneous temperatures can be measured on a variety of surfaces heated by radiation. It discusses a 1000 deg F system, its methods of operation and its performance characteristics. It shows that the 1000 deg F probe operates on a variety of materials with an accuracy generally better than 3/8 percent and with a time constant of the order of 0.1 seconds. A comparison of the performance of permenent surface thermocouple installations using iron-constantan, chromel-constantan and chromel-alumel thermocouples, various thermocouple wire sizes, orientations, rates of heating and surface materials was made with the 1000 deg F probe performance. In almost every case, the accuracy of the probe was better thane the accuracy of permanent surface thermocouple installation. The design of a probe system believed to be feasible for extending the range of operation to 3000 deg F is presented. The report also includes detailed information on the development of the sensor, fabrication of a probe, and a discussion of thermocouple attachment methods to non-metallic surfaces.
