1 Typical circuit thermocouple temperature measurement is different from the explosion-proof thermocouple. It is a circuit used with a moving coil meter and a cold junction compensator. It is a circuit used with an automatic electronic potentiometer (note that the automatic electronic potentiometer has internal Compensation Bridge Road). 2 Positive series connection The thermocouple is connected in series in the positive direction. It is a series connection of the positive and negative poles of the same type of thermocouple. The total input thermoelectric potential of the thermocouple display instrument is: Eu003dEab(t1,to)+Eab(t2,t0). It can be seen that if the same temperature is measured with a forward series circuit, the total input thermoelectric potential of the instrument will be displayed as Eu003d2Eab( t,to), which can improve the sensitivity of the instrument. A thermocouple composed of multiple thermocouples of the same type in series is called a thermopile. It can be used in a radiation pyrometer to measure small temperature changes and obtain a larger thermoelectric potential output. 3 Reverse series connection connect the same-named pole (negative or positive) of the same type of thermocouple, which is the reverse series of thermocouples. The thermocouple composed in this way is called a differential thermocouple. Its extracted thermoelectric potential is △Eu003dE(t1, t0)-E(t2, t0) two E(t1, t2) Therefore, △E reflects the temperature difference between the two temperature measurement points (t1, t1). It is required here that the model of the thermocouple used and the cold cut-off temperature t0 must be the same. And the thermoelectric characteristics of the thermocouple are linear. Such as nickel-chromium-nickel-silicon thermocouple
