1. The platinum resistance temperature measurement range is wider than the copper resistance measurement range.
Copper resistance temperature range: -50 ~ 150 degrees Celsius platinum resistance temperature range: -200 ~ 450 degrees Celsius 2. Platinum resistance has high precision, reliable performance, good oxidation resistance, and stable physical and chemical properties. Compared with other thermal resistances, it has a higher resistivity. It can also be used as a standard device in addition to the initial general temperature measurement elements. Disadvantages are: non-linear relationship between resistance and temperature, the price is more expensive, not suitable for use in reducing medium at high temperatures. 1 B* @+ H5 }+ |& ^3. Copper resistors have low resistivity, are easily oxidized, and can be used when the temperature is not high.
Advantages: The price is cheap, and the resistance value is basically linear with the temperature.
