Temperature and humidity measurement instrument

Abstract

The invention discloses a temperature and humidity measurement instrument. The temperature and humidity measurement instrument comprises a temperature and humidity sensor, an anti-radiation cover anda supporting plate. The anti-radiation cover comprises multiple cover bodies and a bottom support. The outer diameters of the cover bodies from the lower opening end to the upper opening end are gradually reduced. The cover bodies are arranged on the bottom support through lamination, a gap is formed between the cover body of the lowest layer and the bottom support, and a gap is formed between every two adjacent cover bodies. The upper opening end of the cover body of the uppermost layer is hermetically connected with the supporting plate. According to the anti-radiation cover with a lamination structure, the temperature and humidity sensor is prevented from being influenced by rainwater and sun radiation, and the cover also has good air circulation performance. Meanwhile, the wind resistance of the anti-radiation cover is small, the influence of the airflow from the sea surface can be effectively reduced, the influence on the platform posture is avoided, when the atmospheric temperature and relative humidity are measured with a small-sized sea surface movement platform, true and objective measurement data can be guaranteed, and accordingly the accuracy of temperature and humiditymeasurement is improved.

Description

technical field [0001] The invention relates to the field of meteorological parameter measurement, in particular to a temperature and humidity measuring instrument. Background technique [0002] At present, the measurement of atmospheric temperature and relative humidity generally adopts the method of putting measurement sensors in shutters for observation. The shutters used to measure atmospheric temperature and relative humidity on land, ships, and fixed platforms at sea are generally large in size, and the shutters can While shading the sun, it can also ensure the ventilation effect, thereby avoiding the influence of solar radiation on the measurement of atmospheric temperature and relative humidity, and ensuring the authenticity and objectivity of the observation data. However, the large mass and volume of the existing atmospheric temperature and relative humidity measuring instruments used at sea will obviously affect the attitude of the small mobile observation platfor...
