PRESSURE MEASUREMENT DEVICE |
摘要 |
FIELD: physics. ^ SUBSTANCE: pressure measurement device has a sensor in form of a section of coaxial long line with one end capacitor formed by a set of metallic deformable end wall and a flat metal plate, connected to the inner conductor of the coaxial line and lying perpendicular its longitudinal axis and parallel the said metallic deformable end wall which receives external pressure. The pressure measurement device also has an electronic unit for exciting electromagnetic oscillations in the section of the long line and measuring its resonance frequency. The section of the long line is flat topped and has a second capacitor, identical to the first capacitor, which is connected to its second end. The flat metal plate of the second capacitor is parallel to the said metallic deformable end wall. ^ EFFECT: wide range for using the pressure sensor and increase in its sensitivity. ^ 1 dwg |
