    • Optical measurement devices including one or more sealing assemblies are described. The sealing assemblies are configured for use at relatively high temperatures and pressures, such as temperatures over 200 degrees F and pressures over 10,000 psi. The sealing assemblies can include a deformable seal element surrounded on each side by a backup seal element. In some examples, the deformable seal element is formed of a material selected from a group consisting of a fluoroelastomer or polytetrafluoroethylene, and the backup seal elements are formed of a material selected from a group consisting of flexible graphite or metal foil. Optionally, at least one additional seal element functioning as an extrusion barrier can be placed on the opposite side of one or both backup seal elements from the deformable seal element. The additional seal element can be formed of polyether ether ketone or flexible graphite, for example. Additional devices and assemblies are described.
    • 描述了包括一个或多个密封组件的光学测量装置。 密封组件被配置为在相对高的温度和压力下使用,例如超过200华氏度的温度和超过10,000psi的压力。 密封组件可以包括可变形的密封元件,其在每侧由一个备用密封元件围绕。 在一些示例中,可变形密封元件由选自含氟弹性体或聚四氟乙烯的材料形成,并且备用密封元件由从由柔性石墨或金属箔构成的组中选择的材料形成。 可选地,用作挤压屏障的至少一个附加密封元件可以放置在一个或两个备选密封元件的与可变形密封元件相对的一侧上。 例如,附加的密封元件可以由聚醚醚酮或柔性石墨形成。 描述了其他设备和组件。
