Temperature Measurement of Solid Bodies by Contact Method One of the most frequently encountered problems in temperature measurement is measuring the temperature of solid bodies on their surfaces in contact with a surrounding gas or liquid . This may be solved by either contact or non-contact methods. Semi-contact or quasi-contact methods may also be used. Roeser and Mueller (1930) have previously discussed the problem . The non-contact, or pyrometric, methods are described in detail in Chapters 8 to 11 . For a rough estimation of surface temperatures, temperature indicators, described in Section 2.5 are also used. The problem of measuring the...
