Abstract
A method for measuring a pressure between a pair of pressing surfaces in point or linear contact with each other by utilizing a pressure measuring film which causes a pressurized portion thereof to develop a color in proportion with the pressure applied. An elastic sheet is disposed between the pressing surface having the point/linear contact portion and the pressure measuring film so as to decrease the pressure transmitted and applied to the pressure measuring film. The pressure distribution obtained from the colored image formed on the pressure measuring film is used to determine the actual maximum pressure applied between the pressing surfaces. It is possible to measure the large pressure which falls in or exceeds the measurable pressure range of the pressure measuring film.
