FIELD: mechanical engineering. ^ SUBSTANCE: pressure sensor includes thin disk of elastic material, penetrated by channels filled with low compression liquid, connected to pressure meter. Pressure meter is positioned inside the sensor. Along perimeter of disk, air hollow is made, minimal size of which is determined from formula lmin>=c.td, where lmin - minimal size of air hollow; c - soil deformation speed in non-measured direction; td - required effect delay time. ^ EFFECT: increased precision of measurements due to delay of time of effect on sensitive element of side components of pressure. ^ 1 dwg |
