| Abstract: | A piezoelectric stress gauge is described in this paper. Its major performance data are: measuring range 106–108 Pa, response time less than 7μs; non-linearity within ±1% and total stress measurement error within ± 10%. It can be used
for measuring dynamic stress in soil, rock and concrete media as well as dynamic force and dynamic pressure in fluids. |
