Title:
METHOD FOR CALIBRATING CONTACT PRESSURE
Document Type and Number:
Japanese Patent JP3803854
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a calibration method which becomes standards for a reproducibility or an accuracy of values of a contact pressure gage for soft objects and surfaces for measuring a constraining pressure to living bodies, a body pressure to beds or chairs, a wearing pressure of clothes, etc.
SOLUTION: A soft bag 2 of a larger capacity than a capacity of a container 1 is set in the container 1 with an open lid 6. A fluid 3 controlled in pressure by a pressure regulator 4 is sealed in the soft bag 2 and is measured by a pressure gage 7. A face 8 to be measured where the calibration is carried out and a pressure-receiving sensor 9 of the contact pressure gage are set in the soft bag, to which the fluid 3 is brought in contact via the soft bag 2. A contact pressure is calibrated by measured values of the pressure gage 7.
