FIELD: measuring engineering.
SUBSTANCE: sensor has diaphragm with massive cylindrical embedment provided with tin-film strain gauges. Two tin-film strain gauges are sensitive to the tensile deformations and arranged over the diameter at the center of the diaphragm or over periphery as close to the center of diaphragm as possible. The two others tin-film strain gauges are used for compensating temperature error in the unsteady temperature regime and arranged over the periphery of the diaphragm in the zone where deformation caused by the pressure to be measures is absent. All the strain gauges are assembled in a bridge scheme.
EFFECT: enhanced accuracy of measurements.
