Abstract：Short base metal thermocouples is a collective name,covering a kind of detachable base metal thermocouples with short electrode length(electrode length is 300~500mm) and base metal armored couples(length of metal sleeve is 300~500mm). Traditional measuring equipment and methods often fail to accurately measure the indication deviation in the high temperature region (above 300℃). The reason for the inaccuracy is found through experiments. The terminal thermostat is designed and developed to solve this problem and effectively reduce the extended uncertainty of the short-type even value deviation.
