Abstract: 
Analytical expressions and nomograms, are obtained to estimate the sensitivity of differential acoustic-electric measuring pressure converter with an error no more than 5 % and to choose such an arrangement of strain-gauge converters on its sensitive diaphragm element that would ensure an additive temperature error of the measuring pressure converter less than 10-4 К-1.
Keywords: acoustic-electric strain-gauge converters, space instruments, temperature error
