摘　　要：该文设计了用于测量低温液位的微型探针。该探针安装于由微型步进电机驱动的机械传动导杆上,组成低温液位的连续自动测量装置。该装置可用于低温杜瓦和其它低温液体储存装置的液位测量与控制,探针有效行程100—1000mm,测量误差小于1mm,并具有参数存储、显示、远程传输、网络连接与控制等功能。It is designed in this paper that a new micro-probe of liquid level used in the cryogenic fluid. The liquid level probe can be equipped in the devices that are consisted of step motor and mechanic gearing bar. This measurement device can be applied to the cryogenic duwa, as well as cryogenic engineering equipment. The valid routines of probe is from 100 mm to 1000 mm, the mea- surement errors is less than lmm, as well as there are features, such as parameter save and display, far transform, network connec- tion and control etc.
