Abstract
The invention discloses a temperature measuring device. The Temperature measuring device includes a sealed tube, an air pressure sensor and a controller; one end of the sealed tube end is connected with the air pressure sensor; the air pressure sensor is electrically connected with the controller; the controller comprises a central processor and a display device; and the sealed tube is filled with an inert gas. According to an ideal gas state equation pV=nRT, the specification and dimension of the sealed tube are set, and the filled inert gas is determined, and thereafter, parameters V, n and a constant R are obtained, and the temperature T of the gas is in direct proportion with air pressure p; the intensity of the pressure of the gas in the sealed tube is detected in real time through the air pressure sensor; the central processor calculates the current temperature T of the gas according to the equation and the parameters; a temperature numerical value is displayed on the display device; and temperature measurement can be completed.
Description
Technical field
The present invention relates to temperature detection field, in particular to temperature measuring equipment.
Background technology
The Ideal-Gas Equation, also known as perfect gas law, common gas law, is describe perfect gas when beinthebalancestate, the state equation of pressure, volume, amount of substance, Relations with Temperature. It is based upon on the empirical laws such as the specific rule of Bo Yier-Ma Lve, Charles law, Gay-Lussac's law.
Its equation is pV=nRT. This equation has 4 variable: p to refer to the pressure of perfect gas, and V is the volume of perfect gas, and n represents the amount of gaseous matter, and T then represents the thermodynamic temperature of perfect gas; Constant a: R is also had to be ideal gas constant. It may be seen that the variable of this equation is a lot. Therefore this equation is many, applied widely and famous with its variable, to the air under normal temperature and pressure also approximate be suitable for.
Summary of the invention
It is an object of the invention to provide a kind of temperature measuring equipment being convenient for measuring temperature.
For achieving the above object, the present invention adopts following technical scheme, temperature measuring equipment, comprise sealed tube, baroceptor and controller, sealed tube one end is connected with baroceptor, baroceptor is electrically connected with controller, and controller comprises central processing unit and display unit, fills rare gas element in sealed tube. According to the Ideal-Gas Equation pV=nRT, setting sealed tube specification, after determining the rare gas element filled, obtaining parameter V, n and constant R, the temperature T and air pressure p of gas are direct ratio, are detected the pressure of gas in sealed tube in real time by baroceptor, central processing unit is according to equation and parameter, calculate the temperature T of current gas, and displays temperature numerical value on the display apparatus, complete temperature survey.
In some embodiments, rare gas element is helium. Helium chemical property very torpescence, can not burn, can not be combustion-supporting, is safe gas, and helium is also the gas of the most difficult liquefaction, conveniently expands sensing range.
In some embodiments, display unit is charactron. Charactron is connected with central processing unit, receives data and displays temperature numerical value.
In some embodiments, sealed tube comprises spiral section. Spiral section is set, allows sealed tube more fully contact with detection air, allow sensitivity of thermometry greatly improve.
In some embodiments, sealed tube is heat-transfer pipe. Arranging heat-transfer pipe, aspect heat is delivered to the rare gas element in sealed tube, allows temperature detection speed improve.
The useful effect of the present invention is: temperature measuring equipment of the present invention, measuring tempeature highly sensitive, it is possible to place flexibly, is convenient for measuring small space or the place of artificial not easily laying temperature meter, and structure is simple, and effect is good.
