Abstract:

Efforts were continued on the development of a zero to 2500 psi pressure sensor having an overall precision of 14 psi. Present emphasis is on developing a practical instrument based on a velocity of sound technique whose feasibility was demonstrated in earlier work. Newly designed echo selector and detector-transmit coupling circuitry is described and test results presented. Results of an experimental study of the effect of several sound path design parameters on the current status of the project is presented. Author
