Sensor of Ratios of Absolute Gas Pressures

摘要

The article describes a sensor of ratios of absolute gas pressures containing elastic sensitive elements picking up pressures and acting on a compensation spring system transmitting the force onto a tensometric converter which for the purpose of improving the dependability and precision of operation of the sensor and the possibility of checking in under barometric pressure, there is used a supplementary correcting lever which takes into account the imbalance of the effective areas of the elastic sensitive elements and an eccentric (cam) for controlling the lever, the cam acting on the latter's presmatic support.
