AIR PACK TYPE CONTACT PRESSURE MEASURING METHOD

摘要

The contact pressure on an elastic body can be measured by feeding air into a bag (1) made of a thin, flexible and less extensible material, transmitting the pressure from inside the bag (1) interposed between contact portions of a soft article to the outside through a thin tube (2), and measuring the difference between the pressure and the atmospheric pressure. Measurement is conducted by immersing the bag (1) in a horizontal position. The depth of water (A) (mmH2O) is measured. By changing the water temperature while measuring the water temperature, calibration can be carried out making compensation for influence of heat.
