According to the thermocouple provided by the utility model, the length of the U-shaped quartz tube is about two times of that of a general quartz tube, so the purposes of measuring temperature repeatedly and durable service can be effectively achieved, and due to the adoption of the connection frame, the problem that the quartz tube shifts in installation is avoided.
Description
Technical field
The utility model relates to the field of thermopair, especially a kind of repeatedly temperature thermocouple.
Background technology
Thermopair is a kind of temperature-sensing element, is a kind of instrument, and it directly measures temperature, and converts temperature signal to the thermopower signal, converts the temperature of measured medium to through electric appearance (secondary instrument).The ultimate principle of thermocouple temperature measurement is that the material conductor of two kinds of different components is formed the closed-loop path; When there is thermograde in two ends; Just have electric current in the loop and pass through, just exist electromotive force---thermopower, Here it is so-called Seebeck effect (Seebeck effect) between the two ends this moment.The homogeneous conductor of two kinds of different components is a thermode, and the higher end of temperature is the working end, and the end that temperature is lower is a free end, and free end is under certain stationary temperature usually.According to thermopower and functional relationship of temperature, process thermocouple indexing table; Dividing kilsyth basalt is to obtain under the condition of free end temperature in the time of 0 ℃, and different thermopairs has different branch kilsyth basalts.
The thermopair that uses at present; Owing to do not possess the fixedly locating device of quartz ampoule, the assembler is difficult to quartz ampoule is cast in the fire clay head when assembling, causes quartz ampoule cast hour offset direction easily; Cause the measuring accuracy of testing medium; In addition, the perimeter length of the U type quartz ampoule that uses at present is 4～5cm, can not realize repeatedly the purpose of thermometric.
The utility model content
The technical matters that the utility model will solve is: in order to overcome the above-mentioned middle problem that exists, provide a kind of purpose that can reach repeatedly thermometric can avoid the repeatedly temperature thermocouple of quartz ampoule skew simultaneously.
The utility model solves the technical scheme that its technical matters adopted: a kind of repeatedly temperature thermocouple; Comprise the fire clay head of hollow structure, with the link of fire clay head socket connection be arranged on the U type quartz ampoule on the link; Placed platinum wire in the described U type quartz ampoule; Link inside has placed two compensating wires; The end of two compensating wires respectively be set in U type quartz ampoule in the platinum wire two ends be connected, the end face of described U type quartz ampoule and fire clay head is fixed through cement casting.
Described link comprises the first step that is fastened on the fire clay head madial wall and the connecting rod that is fixedly connected and is blocked in the second step on the fire clay head edge and is connected with U type quartz ampoule one end with first step; Described connecting rod comprises the connecting link that is fixed on the first step end face and is connected to the dop of U type quartz ampoule one end with connecting link end integrative-structure and is fixed on the connecting link and is arranged on the strong point of dop below, is fixed with connection-peg on the downside of described second step.
The length of described U type quartz ampoule is 8～10cm, and the length of this quartz ampoule is 2 times of general common quartz ampoule length, and this kind quartz ampoule probe temperature can reach 1700 ℃, can satisfy repeatedly the purpose of thermometric.
The beneficial effect of the utility model is that the repeatedly temperature thermocouple of the utility model adopts the U type quartz ampoule of being longer than 2 times of common quartz ampoules, can satisfy repeatedly the purpose of thermometric effectively, and is durable in use; Adopt link, can avoid when the assembling quartz ampoule, taking place the phenomenon of skew.
