Abstract

The pickup is applicable to the measurement and control of exhaust- gas temperatures in jet engines. The unit consists of a 2-lead platinum resistance thermometer with a sensing element encased in an 18-8 stainless-steel sheath. A flat grid of platinum is embedded in a ceramic insulation and is located within 0.75 in. of the flattened end of the tube. The electrical resistance vs temperature relation was determined for the range of 32 to 1600 F, and the resulting data were plotted. Response records of the pickup unit were obtained for gas-flow rates of 3, 5, and 8 lb/sec sq ft, and the results were tabulated. The recovery factor was determined to be 0.71. The tests indicated that the pickup probe is a rugged instrument which is capable of withstanding the rigors of normal jet engine operation.
