Research on the Performance of Precision Platinum Resistance Thermometers
Based on the standard resistance method,a comparison test on the performance of indication error,indi-cation fluctuation and short-term drift of three kinds of precision platinum resistance thermometers was carried out.At the same time,the influence of different working environment temperature and standard platinum resistance thermometer ITS-90 parameters on the measurement results is tested.The results show that the thermometer has high accuracy and low fluctuation,and the short-term drift of individual samples can reach 0.01℃.The influence of working environment temperature on different models is different,and the parameter of the thermometer has little influence on the measurement result.
