The application and working principle of thermocouple thermometer is introduced

Thermocouple is is most common in temperature measuring instrument, the application range is very wide, but want to market demand is big, so this kind of common temperature measuring instrument why have so much charm? The following countries

instrument experts for you about about the range of application and working principle of thermocouple thermometer. Thermocouple is a temperature sensing element. It directly measuring the temperature and the temperature signal into a thermoelectric emfs signals through electrical instrument ( Secondary instrument) Convert the temperature of the measured medium. Let's understand the working principle of thermocouple thermometer and application scope. A, the working principle and application scope of thermocouple thermometer

the working principle of thermocouple thermometer wire or hot electrode) Two ends synthesis loop, when the junction temperature is not at the same time, in the circuit will generate electromotive force, this kind of phenomenon called the thermoelectric effect, which electromotive force is called thermoelectric

potential. Thermocouple is to use the principle of temperature measurement, which directly used for measuring the medium temperature is called at the end of the working side ( Also known as the measuring end) , on the other side called cold end ( Also known as compensation) ； The cold end and display

instrument or meter connection, display instrument will point out the thermocouple thermoelectric potential. Countries instrument specializing in the production of pressure gauge, pressure gauge, precision pressure gauge, stainless steel pressure gauge, double needle gauge, bellows pressure gauges, diaphragm pressure

table, seismic pressure gauge, electric contact pressure gauge, explosion-proof electric contact pressure gauge pressure gauge series. Second, the application range of the thermocouple thermometer with double metal thermometer, thermocouple or heat resistance temperature transmitting way, both meet the demand of field temperature measurement, also meet the demand of long distance transmission can be directly measured in the process of various production - 80 - + 500 ℃ within the scope of liquid, vapour and gas medium, as well as solid surface temperature measurement. Usage: used for measuring various temperature object, measuring range is great, far greater than alcohol, mercury thermometer. It is suitable for steel furnace, coke oven, such as high temperature area, also can measure the liquid hydrogen and liquid nitrogen temperature object. The above is the content of the working principle of thermocouple thermometer and application scope, the commonly used thermocouple can be divided into two categories, thermocouple and non standard thermocouples. Invokes standard thermocouple is refers to the national standard specifies its thermoelectric potential and the relationship between temperature, permissible error, and a unified standard score table of thermocouple, it has with matching display instrument to choose from.
