Finned temperature sensor

Abstract

The invention discloses a finned temperature sensor. The finned temperature sensor comprises a first shading plate, a first fin heat dissipation plate, a second fin heat dissipation plate and a secondshading plate which are arranged at intervals from bottom to top, wherein the first shading plate, the first fin heat dissipation plate, the second fin heat dissipation plate and the second shading plate are arranged in parallel in the horizontal position and fixed through using a first supporting rod; and a temperature sensor probe is arranged between the first fin heat dissipation plate and thesecond fin heat dissipation plate and is fixed to the first fin heat dissipation plate through using a second supporting rod. The temperature sensor has the beneficial effects that: firstly, direct irradiation and secondary radiation of the sun can be reduced by utilizing the shading plate; and secondly, the fin heat dissipation plates are made of metal material with good heat dissipation performance, so that the influence of internal temperature rise on temperature measurement can be effectively reduced, the thermal radiation pollution on the temperature sensor probe in the anti-radiation cover is reduced, and the radiation error is reduced.

Description

technical field [0001] The invention relates to the technical field of meteorological instruments, in particular to a finned temperature sensor. Background technique [0002] The temperature sensor is a commonly used temperature sensor in meteorological observation. When the temperature sensor performs meteorological measurement, the measurement accuracy of the sensor will be affected by many factors, such as solar radiation, component wetting, self-heating effect, long-wave radiation, etc. With the increasing requirements for temperature detection accuracy, how to reduce the measurement error of temperature sensors has become an urgent problem to be solved. As an important factor affecting the detection performance of temperature sensors, solar radiation has become a research hotspot in this field. In order to reduce the impact of solar radiation on Due to the influence of temperature measurement, temperature sensors of various specifications have appeared on the market, su...

AI Technical Summary

Problems solved by technology

The use of blades or rings can help reduce radiation errors, but it is difficult to make the airflow velocity sensed by the temperature sensor probe as large as possible, so it is difficult to eliminate the effect of thermal pollution

Therefore, there is a contradiction between the above two design requirements, which brings difficulties to the improvement of the performance of the temperature sensor.
