17 Platinum resistance thermometer Sheath (protective tube) Internal filler(mgo) V Resistance element(pt) Internal conductor constant-current power supply Example of the relationship between temperature and resistance
18 Liquid in glass thermometer Principle; Liquid in glass thermometers make use of the differential expansion of a pure liquid with respect to its glass container to indicate the Temperature. Precaution for use; If bubbles or breakage in the liquid column are found, repair is necessary. Check that the scale plate of a thermometer does not move, and that the scale mark has not disappeared.
19 Liquid in glass thermometer Caution for reading; The observer ensures that the straight line from his/her eye to the meniscus, or index.
