    • A pressure measuring device includes a partially coiled tube having a closed end and an opposite open end. The closed end is rolled and set into a coiled configuration. The device also includes a partially coiled tube supporting structure having a pressure indicating scale. The supporting structure holds the partially coiled tube such that the open end of the tube is in communication with a fluid whose pressure is to be measured. Pressure applied by the fluid causes the tube to unroll and the closed end of the tube to be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.
    • 压力测量装置包括具有封闭端部和相对开口端部分的部分盘管。 封闭的端部被卷起并设置成卷绕构型。 该装置还包括具有压力指示标尺的部分盘绕管支撑结构。 支撑结构保持部分卷绕的管,使得管的开口端与要测量其压力的流体连通。 由流体施加的压力导致管展开,并且管的封闭端相对于压力指示刻度显着地移位与流体施加的压力相关的距离。
