摘要

描述了一种用于确定组织低温保存容器中冷冻剂水平的简单液体传感和测量系统。通过检测串联发光二极管的热瞬态来确定液气边界。位于容器外壁上的电子控制和显示单元指示低温液体的液位，并在达到预定的临界液位时向操作员发出警报。

A method for liquid cryogen level measurement in cryopreservation containers

A simple liquid sensing and measurement system for determining the level of cryogen in a tissue cryopreservation container is described. Liquid-gas boundary determination is made by detecting a thermal transient of the series-connected light emitting diodes. An electronic control and display unit located on the outer wall of the container indicates the level of cryogenic liquid, and alarms the operator if it reaches a pre-determined critical level.
