    • A temperature compensated bellows is provided for storage and displacement of a first fluid used as an indicator in a capillary tube. The bellows is made of a housing made of flexible, watertight material. The housing is made up of an upper portion, a lower portion, and an outer accordion formed portion. The accordion formed portion has a length / and is sealingly connected along a periphery between the upper and lower portions. At least one entry/exit port formed on at least one of the portions thereof. At least one of the upper and lower portions extends from a periphery of the accordion formed portion substantially within the housing so as to reduce the storage volume. Preferably, within this area defined by the portion which extends within the housing, a temperature compensation device is disposed. This device is made up of a miniature bellows and reservoir in which a second fluid is placed having a coefficient of expansion which is different than the first fluid. The device is arranged to allow expansion of the second fluid to negatively affect the displacement of the first fluid in the capillary tube. In this manner, the appropriate selection of a first and second fluid allows for temperature compensation, so as to yield an indication which is consistent and accurate across a large range of temperatures.
    • 提供温度补偿波纹管用于在毛细管中用作指示剂的第一流体的储存和移位。 波纹管由一个由柔性,防水材料制成的外壳制成。 外壳由上部,下部和外部卷边形成部构成。 手风琴形成部分具有长度并沿着上部和下部之间的周边密封地连接。 在其至少一个部分上形成的至少一个入口/出口。 所述上部和下部中的至少一个从所述手风琴形成部分的周边基本上在所述壳体内延伸,以便减小所述存储容积。 优选地,在由在壳体内延伸的部分限定的该区域内,设置温度补偿装置。 该装置由微型波纹管和储存器组成,其中放置第二流体,其具有与第一流体不同的膨胀系数。 该装置被布置成允许第二流体膨胀以负面地影响毛细管中的第一流体的位移。 以这种方式,对第一和第二流体的适当选择允许温度补偿,从而产生在大范围的温度范围内一致和准确的指示。
