PRESSURE TRANSDUCER FOR MEASURING SHOCK WAVE PROFILES. PHASE X. MEASUREMENT OF LOWPRESSURE SHOCK WAVE PROFILES.
Abstract
Lead, indium, cadmium, calcium, and three ironnickel alloys were investigated as pressure sensing materials for a low pressure (5 to 25 kbar) piezoresistive transducer. A configuration that employs a vacuum-deposited film piezoresistive element was tested and found practical. The calcium transducer, which uses a vacuum-deposited calcium element and Hi-D glass insulator, appears promising after a preliminary test. The heat flow between the insulator and the piezoresistive element was calculated; the results of this calculation indicate that timedependent corrections to the resistance-time profile are required for certain piezoresistive material-insulator combinations.
