A thermometer is how to work? For you below describes the various thermometer principle of
work:
1.
Gas thermometer: multi-temperature material with hydrogen or helium, hydrogen and helium
liquefaction temperature is very low, close to absolute zero, so its a very wide temperature range.
This thermometer accuracy is high, used for precision measurement.
2.
Resistance thermometer: divided into metal resistance thermometers and the semiconductor
resistance thermometers are made of this feature of the temperature dependence of resistance
value.
Metal thermometer useful for pure metals such as platinum, gold, copper, nickel and
rhodium iron, phosphor bronze alloy; the semiconductor thermometer with carbon, germanium.
Resistance thermometer is easy to use and reliable, has been widely applied.
Measurement
range from -260
to 600
