Temperature sensor array with flow guide discs

Abstract

The invention discloses a temperature sensor array with flow guide discs, which comprises two disc-shaped shading plates, two flow guide discs with wave crest-wave trough sections, a plurality of heat insulation support columns, and a temperature sensor probe array of not less than three temperature measuring elements, a disc-shaped shading plate, a first flow guide disc, a second flow guide disc and a disc-shaped shading plate are sequentially arranged in parallel from top to bottom, the center points of the four are located on the same vertical line and are perpendicular to the horizontal plane, and the first disc-shaped shading plate, the first flow guide disc, the second flow guide disc and the second disc-shaped shading plate are connected through a plurality of heat insulation supporting columns. The disc-shaped shading plate can effectively block radiation and effectively reduce the influence of secondary radiation on the sensor probe array caused by various kinds of radiation entering the equipment; a ventilation pipeline is arranged in the middle of the flow guide disc, so that the airflow speed around the sensor probe array can be effectively improved; and a plurality of temperature sensor probes are used for measuring together, so that one sensor probe can sense external air in real time under any wind direction condition, and the measuring precision and the response speed of the sensor are improved.

Description

technical field [0001] The invention relates to a temperature sensor array, in particular to a temperature sensor array with a guide plate. Background technique [0002] In the process of measuring the air temperature, the temperature sensor of the weather station is affected by direct solar radiation, ground reflected radiation, long-wave radiation, and scattered radiation, which will cause differences between the measured value of the temperature measuring element and the real air temperature value. In order to reduce the measurement error caused by radiation, effective radiation shielding measures must be taken for temperature measuring components. At present, the radiation protection equipment commonly used in weather stations includes shutters and radiation shields. However, the outer wall of the traditional shutter or radiation shield still has a certain absorption effect on radiation, especially after the coating ages, the absorption effect increases rapidly, which c...

Problems solved by technology

At present, it is easier to meet the first design requirement or the second requirement, but it is difficult to meet the above two design requirements at the same time

These two design requirements are contradictory, which brings difficulties to improve the performance of meteorological temperature sensors.
