Figure.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Referring to Fig. 1, the structure for a kind of level monitoring device suitable for liquid nitrogen container provided by the utility model is shown
It is intended to, it includes single-chip microcomputer 1, display module 2, alarm module 3, is that single-chip microcomputer 1 and display module 2 and alarm module 3 are powered
Power supply module 4, support 5 and the RTD array 6 being fixed on support 5.Wherein, single-chip microcomputer 1, display module 2, alarm
Module 3 and power supply module 4 are installed in the outside of the liquid nitrogen container, and RTD array 6 is immersed in the liquid nitrogen of the liquid nitrogen container, and
RTD array 6 is connected by wire with single-chip microcomputer 1.
Support 5 is metal material, for fixing and protecting RTD array 6 and wire.Support 5 is close to the liquid nitrogen container
Inwall is installed.In the present embodiment, support 5 is in elongated plate.
RTD array 6 includes some RTDs, and some RTDs are each attached on support 5.In the present embodiment,
Some RTDs, which are vertically arranged, to be in line, and by being connected again with single-chip microcomputer 1 after wired in series.
