Research on Methods of Improving Platinum Resistance Sensor’s Temperature Measurement Precision

Abstract:

Platinum resistance sensor is widely used in meteorological observation. In order to ensure the quality of temperature observation data, a number of experiments in different humidity, different working current, and in a constant temperature water tank and dry oven and other environments are completed with platinum resistance sensors. The experimental results are analyzed to investigate the influence factors of platinum resistance temperature measurement accuracy. The experiments can provide basis for objective evaluation of platinum resistance temperature sensor’s performance index, and for platinum resistance temperature sensor’s production, test, use and other areas, and can ensure quality of meteorological observation data.
