A static high-temperature strain gage using Karma wire and either Quigley 1925 or Brimor U529 ceramics has been found to be satisfactory for measuring static strains at temperatures up to 800 F. The gage can be used in situations involving variable temperatures as well as a constant temperature during the loading and unloading cycles. For dynamic strain measurements at temperatures up to 1500 F, a coating material developed by the U. S. Army Corps of Engineers at the Fort Belvoir Laboratories has been found to be superior to other cements tested. A high degree of success has been obtained with this material in mounting gages on turbine blades and combustor liners of turbojet engines.
