摘　　要：参照JJF 1183-2007《温度变送器校准规范》,对四种不同量程温度变送器进行校准,本文仅选用了温度0℃时的校准状态,并对其测量误差的不确定度进行评定。温度变送器在其他温度下的校准状态和测量误差的不确定度评定与本文描述过程等同。According to JJF 1183-2007 " calibration specification of the temperature transmitter",the temperature transmitters with four different ranges are calibrated. In this paper,only the calibration state at 0 ℃ is selected,and with the measurement uncertainty evaluation. The calibration state of the temperature transmitter and the measurement uncertainty evaluation at other temperatures is the same as that described in this paper.

关 键 词：不确定度 温度变送器 校准
