应用于气象探测的双加热温度传感器设计∗
Design of a Heated Twin Temperature Sensor Used in Meteorology Observation
摘要
Abstract
In order to compromise the measurement error caused by the deposition of water on the temperature sen-sors in high-altitude meteorological observation,a heated twin temperature sensor is proposed. The changes of the measurement error and time constant under different wind velocities and precipitation intensities are measured by al-ternately heating the two temperature sensing devices. By fitting the corresponding function,the error correction and precipitation intensity measurement are achieved. The test results show that under certain wind velocities and pre-cipitation intensities,this design can reduce the error caused by water evaporation from ±0.3 ℃ to below ±0.1 ℃. The precipitation intensity measurement error is ± 0. 2 mm/min. Compared with traditional radiosonde temperature sensors,the heated twin temperature sensor features high precision and has the capability of error elimination. The measurement of precipitation intensity is also realized in this design.关键词
