Abstract

The invention discloses a temperature sensor. The temperature sensor comprises a base, and the top of the base is fixedly connected with two supporting columns, a motor switch and a motor fixing frame. The tops of the supporting columns are fixedly connected with a first flow guide light shield, and the top of the first flow guide light shield is fixedly connected with three first heat insulation fixing rods and three fixing columns. The tops of the three first heat insulation fixing rods are fixedly connected with a first flow guide device. The tops of the three fixing columns are fixedly connected with a second flow guide light shield, an electric heating layer is arranged in the second flow guide light shield, and the bottom of the second flow guide light shield is fixedly connected with a second heat insulation fixing rod. The first flow guide device and a second flow guide device are each of a curved surface structure. The air flow can be further guided to flow to a temperature sensing probe, and the speed of the air flow around the temperature sensing probe is effectively increased. The surfaces of the first flow guide device and the second flow guide device are plated with a high-reflection material, various kinds of radiation can be effectively reflected, radiant heat is reduced, and therefore the influence of heat conduction on the temperature sensing probe is reduced.

Description

technical field [0001] The invention relates to the technical field of electronics and information engineering, in particular to a temperature sensor. Background technique [0002] Since various radiations such as direct solar radiation, reflected radiation, scattered radiation, and long-wave radiation will affect the measurement of the temperature sensor used for meteorological observation, at present, the weather station often installs the temperature sensor in the shutter box or the radiation shield. Avoid all kinds of radiation directly illuminating the temperature sensor. However, since the white coating on the surface of the shutters and radiation shields is difficult to completely block various radiations, the shutters and radiation shields will still generate radiation heating, which will cause the surrounding air to be heated and flow into the interior, thus making the temperature sensor cause measurement errors. In addition, the blades of the shutter and the ring...
