Estimates of Galvanic Couples and Resistors
Thread Content
There are quite a lot of galvanic couples, resistors, and degree meters. Can an expert provide a method that can be used to estimate on site, without having to bring a graduation meter to the site?
Yes, if you look at the thermal resistor 100, it is 0 degrees, and 119 is around 50. Then how much is 138? Don’t you know what the relationship is?
Thermal resistance Pt100 is 1° per 0.4 ohm, thermocouple: One degree is probably 0.04mv 10 degrees 0.397mv 20 degrees 0.798mv 30 degrees 1.203mv 40 degrees 1.611mv 50 degrees 2.022mv 100 degrees 4.095mv 500 degrees 20.640mv 1000 degrees 41.269mv This post was last written by jamutolog Edited at 2009-4-17 07:47 ]
Thermocouples have many graduation numbers. You can write down the thermoelectric potential at special temperature points of commonly used graduation numbers. The shortest way is to use a temperature tester, which can directly read the temperature and graduation value.
Measure with the Thermal Codex, which can directly convert signals into temperatures
We also use Thermal Engineering Manual, which is very convenient and does not require a comparison table.
You can buy a detection dictionary and all problems will be solved. It can not only measure resistance and millivolts, but also directly check the temperature.
