For a fixed-point temperature is defined between, between 259.34 ~ 630.74 ℃, using a platinum resistance thermometer as the reference standard device. Ke force load cell reference platinum resistance thermometer is made uniform, 0.05 ~ 0.5mm in diameter,portable fuel transfer pump completely annealed and no strain platinum wire.
Baidu platinum wire temperature sensor resistance ratio W (100) = Rloo / R. = 1.39250, wherein Ro, Rloo respectively resistance 0 ℃ and 100 ℃ time. Between a Mettler Toledo weighing sensor 630.74 1064.43 ℃,fuel card management system standard uses of germanium is platinum, a platinum standard thermocouple. Above 1064 .43 ℃, using optical pyrometer as a standard device. Temperature sensors or load cells in different standard temperature ranges calculated temperature is defined between the points according to the different interpolation formula.
