DYNAMIC TESTING OF GAS SAMPLING THERMOCOUPLES 600219
The performance characteristics of gas sampling thermocouples used in the Allison Model 501 engine are discussed. Various environmental factors affecting performance of the thermocouple are analyzed and criteria established for the testing of such components. Description of a new high-temperature flowing gas thermocouple test rig and general performance data of the equipment is presented. Test procedures and analysis of calibration data are discussed. Fourteen figures are presented to illustrate the characteristics of the thermocouple and features of the test equipment.
