A thermocouple is formed by two dissimilar electrical conductors which are connected at one end and intended to determine the temperature. The measurement of the thermocouple is protected against chemical or mechanical damage to the heat-resistant tubes. Widely used for the measurement devices in gaseous and liquid medium, heat treatment furnaces, industrial heating plants, metallurgical equipment.
The thermoelectric effect is that between the dissimilar conductors at higher temperatures there is a potential difference which is dependent on the degree of heating. Calibrate thermocouple can obtain accurate data about the temperature to within a degree. Such a device provides measurement of temperature differences arising between their work and the conventional soldering soldering, which is formed by the ends of the thermocouples.
They have the same color code. Positive pole is marked in red. It is necessary to monitor compliance with the fields in the connection, otherwise there may be large errors.
A wide range of thermocouples for measuring the temperature of any range. Availability — you can buy in any specialty store. You can find shops that provide favorable conditions of supply the entire range of products. It is possible to manufacture thermocouple for special orders. Not the last role is played by the reasonable price. Among the advantages of the thermocouple should be noted low inertia. They measure the smallest temperature differences. A measurement of high temperatures in aggressive environment would be impossible without them.
Manufactured according the State Standard requirements for different types and classes of thermocouples. TEDS values from one skein is usually identical to certified, and have pieces of different coils may differ materially. For the highest accuracy thermocouple is checked on thermoelectrodes homogeneity. If necessary measures are taken to reduce heterogeneity.
Thermocouple wires coming into the trading network of the different points of the world. For example, China supplied thermocouple wire + Chromel alumel. For this component of the thermoelectric device is close to a straight line. High nickel content in such a thermocouple provides high resistance to oxidation. The maximum temperature in operation 400 ° C. Insulation material — glass of red and yellow
To improve the accuracy of thermocouple:
— Can only be used in a range of operating temperature
— Used thermocouple wire of large diameter
— Eliminates mechanical tension and vibration
— Excluded are sharp temperature gradients along the length of the thermocouple
— When using protective covers are used in aggressive environments
— Extension cords are used in the operating range with a small temperature gradient;
— It is a continuous electronic monitoring thermoelectrodes resistance;
— In order to further improve the quality of special thermocouple measurements are used that enable you to further control the electrical resistance and voltage noise.
Purchase of thermocouples
The amount of the precious metal is determined by weighing Lessons from the protective capsule heating elements — wires containing precious metal is wound into a ball, check, and then all the balls together weighed. The total weight is multiplied by the corresponding sample and calculate the amount of pure platinum. After this number is multiplied by a factor of currency, and get the product price at the rate of today.
