Abstract
The utility model discloses a temperature measurement device. Temperature measurement device, including sealed tube, baroceptor and controller, sealed tube one end is connected with the baroceptor, and the baroceptor is connected with the controller electricity, and the controller includes central processing unit and display device, packs inert gas in the sealed tube. According to equation of state of ideal gas pV=nRT, setting for sealed tube specification and dimension, behind definite inert gas who packs, obtain parameter V, n and constant R, gaseous temperature T is the direct radio with atmospheric pressure p, and through pressure gaseous in the baroceptor real -time detection sealed tube, central processing unit draws current gaseous temperature T according to equation and parameter, calculation to show temperature value on display device, accomplish temperature measurement.
Description
Technical field
This utility model relates to temperature detection field, particularly to temperature measuring equipment.
Background technology
The Ideal-Gas Equation, also known as perfect gas law, general gas law, be describe ideal gas when beinthebalancestate, pressure, volume, the amount of material, the state equation of Relations with Temperature.It is set up on the empirical laws such as Bo Yier-boyle's law, Charles' law, Gay-Lussac's law.
Its equation is pV=nRT.This equation has 4 variable: p to refer to the pressure of ideal gas, and V is the volume of ideal gas, and n represents the amount of gaseous matter, and T then represents the thermodynamic temperature of ideal gas；Also having constant a: R is ideal gas constant.It can be seen that the variable of this equation is a lot.Therefore this equation is many, applied widely and famous with its variable, is suitable for the air under normal temperature and pressure the most approx.
Utility model content
The purpose of this utility model is to provide a kind of temperature measuring equipment being convenient for measuring temperature.
For achieving the above object, this utility model adopts the following technical scheme that, temperature measuring equipment, including sealing pipe, baroceptor and controller, seal pipe one end to be connected with baroceptor, baroceptor is electrically connected with the controller, and controller includes central processing unit and display device, fills noble gas in sealing pipe.According to The Ideal-Gas Equation pV=nRT, setting sealing pipe specification, after determining the noble gas of filling, obtaining parameter V, n and constant R, temperature T of gas is proportional with air pressure p, is detected in real time by baroceptor and seals the pressure of gas in pipe, central processing unit is according to equation and parameter, calculate temperature T of current gas, and displays temperature numerical value on the display apparatus, complete temperature survey.
In some embodiments, noble gas is helium.Helium chemical property very torpescence, can not burn, can not be combustion-supporting, is safe gas, and helium is also the gas being most difficult to liquefaction, convenient expansion detection range.
In some embodiments, display device is charactron.Charactron is connected with central processing unit, receives data displays temperature numerical value.
In some embodiments, seal pipe and include spiral section.Spiral section is set, allows sealing pipe more be fully contacted with detection air, allow sensitivity of thermometry be greatly improved.
In some embodiments, sealing pipe is heat-transfer pipe.Arranging heat-transfer pipe, aspect heat is delivered to seal the noble gas in pipe, allows temperature detection speed improve.
The beneficial effects of the utility model are: this utility model temperature measuring equipment, measure the highly sensitive of temperature, can place flexibly, are convenient for measuring small space or are manually difficult to place the place of thermometer, and simple in construction is respond well.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 1, temperature measuring equipment, including sealing pipe 1, baroceptor 2 and controller 3, seal pipe 1 one end to be connected with baroceptor 2, baroceptor 2 electrically connects with controller 3, controller 3 includes central processing unit and display device 31, fills noble gas in sealing pipe 1, and noble gas is helium.
Display device 31 is charactron.
Seal pipe 1 and include spiral section 11.
According to The Ideal-Gas Equation pV=nRT, setting sealing pipe 1 specification, after determining the noble gas of filling, obtaining parameter V, n and constant R, temperature T of gas is proportional with air pressure p, is detected the pressure sealing the inner helium of pipe 1 in real time by baroceptor 2, central processing unit 3 is according to equation and parameter, calculate temperature T of current gas, and displays temperature numerical value in display device 31, complete temperature survey.
Spiral section 11 is set, allows sealing pipe 1 more be fully contacted with air to be detected, allow sensitivity of thermometry be greatly improved, simultaneously by arranging screw diameter and the number of turns of spiral section 11, the sensitivity of the different size of temperature measuring equipment can be set.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, on the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
