Abstract

The invention relates to the technical field of intelligent control and intelligent detecting, in particular to a magnetic pointer type non-contact temperature, pressure, liquid level measuring transmitter for an opening-free nuclear vessel. The measuring transmitter comprises a nuclear vessel sealing shell, a vessel inner temperature parameter measuring and converting unit, a vessel inner pressure parameter measuring and converting unit, a vessel inner liquid level parameter measuring and converting unit and a magnetic pointer measuring transmitting unit, wherein the vessel inner temperature parameter measuring and converting unit and the vessel inner pressure parameter measuring and converting unit are located above the nuclear vessel sealing shell, the vessel inner liquid level parameter measuring and converting unit is located on one side of the nuclear vessel sealing shell, and the temperature, pressure, and liquid level parameters can be measured at the same time. The magnetic pointer type non-contact temperature, pressure, liquid level measuring transmitter has the advantages that the influence of the zero voltage shifting of linear Hall sensors on precise interpolation positioning is solved through environment temperature compensation, and the problems that precision is lowered and measuring cannot be performed due to the fact that an external magnetic pointer measuring transmitting unit is far away from the vessel inner measuring and converting units and the magnetic field signals of a magnetic pointer are weak are solved.

Description

technical field [0001] The invention relates to a magnetic pointer type non-contact temperature, pressure and liquid level measuring transmitter for nuclear containers without openings, belonging to the technical field of intelligent control and intelligent detection. Background technique [0002] For the production of nuclear raw materials, safe operation is the top priority. In the design of the nuclear industry production process, in order to ensure the safety of the system, it is not allowed to design the installation openings for the installation of the material parameter detection transmitter on the pressure vessel. This "safety constraint" has brought great troubles to the design of system safety monitoring and automatic control functions. Due to the confidential nature of the nuclear industry, the international nuclear industry giants keep secrets of related core technologies secret. At present, in the production process of nuclear materials in my country, the prac...
