Commercial strain gages were evaluated for proposed strain measurement on a Rene'41 honeycomb test panel to be subjected to temperatures from -432F to +1600F. Foil strain gages of three different temperature compensations, a weldable strain gage and a capacitive strain gage were tested to determine characteristics of apparent strain, strain sensitivity, and temperature operational limits under stabilized temperature and several heating and cooling temperature rates. Test results show that strain measurement over the total temperature range can be made using a combination of gages.
