二等铂电阻温度计标准装置

用二等标准铂电阻温度计检定标准水银温度计是根据我国国家检定规程JJG161-2010来检定，将二等标准铂电阻温度计作标准器与标准水银温度计置于同一恒定温度下采用比较法进行检定。按标准→被检；被检→标准顺序读数，如此往返4次，然后计算标准及被检的读数平均值，并计算标准水银温度计在该点的修正值。 检定工业铂、铜热电阻是根据我国国家检定规程JJG229-2010来检定，分别在0℃和100℃测定标准铂电阻和被检热电阻的电阻值。通过标准铂电阻计算恒温槽偏离温度，从而计算被检热电阻的电阻值和实际电阻温度系数α。Calibration of standard mercury-in-glass thermometers using second-class standard platinum resistance thermometers is conducted in accordance with China's national verification regulation JJG161-2010. The second-class standard platinum resistance thermometer (as the reference standard) and the standard mercury-in-glass thermometer are placed in the same constant temperature environment, and calibration is performed via the comparison method. Readings are taken in the sequence of reference standard → device under test (DUT), then DUT → reference standard, repeating this cycle four times. Subsequently, the average readings of the reference standard and the DUT are calculated, and the correction value of the standard mercury-in-glass thermometer at this temperature point is computed. Calibration of industrial platinum and copper resistance thermometers is performed according to China's national verification regulation JJG229-2010. The electrical resistance values of the reference platinum resistance thermometer and the resistance thermometer under test are measured at 0℃ and 100℃ respectively. The temperature deviation of the constant temperature bath is calculated using the reference platinum resistance thermometer, and then the electrical resistance value and the actual resistance temperature coefficient α of the resistance thermometer under test are derived.
