Abstract

PURPOSE:To obtain a smaller size and a lower cost by indicating the movement of a liquid column which is so arranged that a gas column is sealed into a spiral hollow tube having a sealed end and an open end. CONSTITUTION:A hollow tube 1 having a sealed end 3 and an open end 2 is made spiral and a liquid column 5 is placed on the side of the sealed end 3 to seal a gas column 4. When a pressure rises in a container due to a gas generating reaction or the like, the pressure in the gas column is reduced until it balances the pressure applied from the open end 2 and accordingly, the liquid column 5 moves to the sealed end 3. An indication piece 6 is shifted thereby to indicate the maximum pressure.
