Pt100 platinum thermal resistance of popular science1

Believe everyone for platinum thermal resistance or have a certain understanding, the following engineering science to you about related knowledge:

the commonly used thermal resistance is generally for the platinum thermal resistance, models of Pt100 or pt10000, other such as Cu50 usage. Thermal resistance is based on the principle of temperature resistance size changes over temperature measurement, there is a conductor wiring resistance compensation, namely common three wire connection, have positive and negative side, respectively, a thread was right in the end, the other end compensation side two wires to connect. In - common temperature measurement range 50℃~+300℃。

and thermocouple types are many, such as S, R, B, K, N, etc. , it is the principle of the different parallel metal plates according to the temperature change will produce a faint induction electric potential difference, this difference can be based on corresponding relationship into temperature values. Common type is K type thermocouple, because of its good linear relationship. General thermocouple temperature measurement range is wide, is suitable for temperature above 500 ℃, can meet the 0 ℃ - — + 1000 ℃ temperature measurement, some can be up to + 2000 ℃. Such as boiler with thermocouple temperature measurement. Its connection for two lines, has positive and negative side.
