Abstract
The utility model relates to a multipoint thermocouple temperature detector, comprising a plurality of temperature transmitters connected with a power supply. The input ends of the temperature transmitters are connected with a multipoint temperature-detecting thermocouple wire connected with the object to be detected; the output ends of the temperature transmitters are connected with a data collecting card connected with the computer. The power supply converts the 220V alternating current to 24V alternating current for being sent to the temperature transmitter; the input end of the temperaturetransmitter is connected with a compensation guide line, and the other end of the compensation guide line is connected with the temperature detecting thermocouple wire. After the output signal of thetemperature transmitter is collected, the temperature signal is input the computer, thus detecting, recording and storing the temperature of a plurality of points (more than or equal to three) and the changing condition, reflecting the variation rule of the temperature in different areas of the object to be detected, and forming a temperature field. The utility model has the advantages of simplestructure, convenient operation and good using effect.
Description
Technical field
The utility model relates to a kind of multiple spot thermocouple temperature measuring apparatus, especially a kind ofly is applicable to inner one or more the temperature survey of object pressed compact in the burning building-up process.
Background technology
Existing conventional temperature survey equipment is various in style on the market, for example, mercury thermometer, electronic thermometer and various K type thermopair, but their function is all more single, generally can only measure single-point object surfaces temperature, can't Measuring Object the situation of change of inner multi-point temp, also be difficult to measure the high temperature more than 2000 ℃.
Combustion synthesis technology is that the heat energy that utilizes raw material itself to discharge prepares material, promptly in course of reaction, utilize the heating certainly of high chemical reaction heat between the reactant and certainly the conduction effect come synthetic material.When reactant in case lighted, the heat that chemical reaction is emitted makes contiguous temperature of charge raise suddenly and causes new chemical reaction, chemical reaction spreads by the entire reaction thing with the form of ripple, reactant changed product into when combustion wave advanced reach.
Existing combustion synthesis technology adopts thermoelectric occasionally infrared pyrometer to measure the adiabatic temperature of burning building-up process, it is certain some temperature situation over time, the variation of multi-point temp (〉=3 point) can't be reflected, thereby the temperature field of burning building-up process can not be made up.The structure of existing burning synthesis temperature field all is to adopt method for computer simulation, can not reflect actual conditions fully, therefore is necessary to develop a kind of multiple spot thermocouple temperature measuring apparatus.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to use, the thermocouple temperature measuring apparatus that the energy measurement multi-point temp changes.
The technical scheme that its technical matters that solves the utility model adopts is: it comprises a plurality of temperature transmitters that link to each other with power supply, the input end of a plurality of temperature transmitters is connected with the multi-point temperature measurement thermocouple wire that links to each other with testee, and the output terminal of a plurality of temperature transmitters is connected with the data collecting card that is connected with computing machine.
Described power supply is the 24V power supply; Described multi-point temperature measurement thermocouple wire has 3 strands at least, the temperature variations of 3 of energy measurements and above point; The lead that described a plurality of temperature transmitter connects the multi-point temperature measurement thermocouple wire is a compensating wire, and the outside of compensating wire is provided with the compensating wire shell; Described temperature thermocouple silk is selected W-Re or platinum rhodium thermocouple silk for use.
Beneficial effect: the utility model comprises 3 and above thermocouple wire at least, promptly can measure the temperature variations of 3 and above point at least.Have following outstanding advantage:
1) measures, writes down, stores the temperature value and the situation of change thereof of multiple spot (〉=3 points) simultaneously, especially can measure the temperature variation of different parts as required.
2) by multipoint temperature measuring, can truly reflect zones of different variation of temperature rule, make up the temperature field.
3) can select multiple thermocouple wire, measure the temperature variations of different temperatures scope.
