What is the relationship between the thermoelectric potential of the thermocouple and the temperature?
With the rapid development of industry, K-type thermocouple
Platinum and rhodium thermocouple armored thermocouple in the production of more and more widely used, its universality covers the vast majority of enterprises, many people for thermocouple and thermal resistance awareness is also more and more. We through a variety of channels to understand and analyze the thermocouple related technology for the majority of users show a wide range of industry knowledge.
So then we come to understand the thermocouple thermocouple and the relationship between temperature?
The thermocouple is calculated from millivolts to temperature: the cold end temperature is measured, converted to the corresponding millivolt value, and the millivolt of the thermocouple is added to the temperature. From the temperature to millivolt: measure the actual temperature and cold side temperature, respectively, converted to millivolt value, subtraction obtained after the millivolt value, that is, the temperature.
Thermocouple of thermocouple:
1: the thermoelectric power of the thermocouple is the function of the temperature difference between the two ends of the thermocouple working end, rather than the thermocouple cold end and the working end, the temperature difference between the two ends;
2: thermocouple generated by the size of the thermoelectric power, when the thermocouple material is uniform, regardless of the length and diameter of the thermocouple,
3: When the thermocouple of the two thermocouple wire material composition is determined, the thermoelectric thermoelectric power of the size, only with the thermocouple temperature difference; if the thermocouple cold end of the temperature to maintain a certain thermocouple thermocouple only The single - valued function of the working - end temperature.
The thermocouple welds two different materials of conductors or semiconductors A and B to form a closed loop, as shown. When there is a temperature difference between the two dedicated points 1 and 2 of conductors A and B, an electromotive force is generated between them, resulting in a magnitude of current in the loop, which is called a thermoelectric effect. Thermocouple is the use of this effect to work.
With regard to the thermoelectric potential of the thermocouple, we need to grasp the above precautions, which is to ensure the normal operation of the guarantee. We are a professional manufacturer of thermocouples to provide you with the most suitable instrument for you. To ensure that the same quality in the lower price, the same price in the better quality.
