* Question
| What are the basic requirements for electrode materials for thermocouples? |
* Answer
| 1 In the temperature range, the thermoelectric properties are stable, do not change at any time, have sufficient physical and chemical stability, and are not easy to oxidize or corrode;
2 the temperature coefficient of resistance is small, the conductivity is high, and the specific heat is small; 3 the thermoelectricity is generated in the temperature measurement.It’s going to be big, |
