Ultraviolet sensor possessing constant temperature apparatus

Abstract

The invention relates to an ultraviolet sensor possessing a constant temperature apparatus. The ultraviolet sensor comprises a shell and a photoelectric inductor. The constant temperature apparatus is arranged in the shell. The photoelectric inductor is installed in the shell through the constant temperature apparatus. The constant temperature apparatus collects a working temperature of the photoelectric inductor in the shell and compares the collected working temperature with a preset temperature so that the photoelectric inductor works in a preset temperature range. According to the invention, an adverse effect of a temperature characteristic of the photoelectric inductor on radiation measurement can be radically eliminated; measuring precision of an ultraviolet radiation sensor can be greatly increased; an actual need of all-terrain, high-precision and perennial field ultraviolet radiation monitoring can be satisfied. One-end strengthened heat insulation effect can be formed through a heat insulation tube so as to reduce a constant temperature point heat flow diffusion rate. One-end strengthened heat dissipation performance is formed to reduce a general structure design scheme of a continuous increasing trend of cold and hot end temperature difference. Therefore, temperature control performance can be reinforced. Power consumption of the constant temperature control can be reduced. A structure is compact.

Description

technical field [0001] The invention relates to an ultraviolet sensor, especially an ultraviolet sensor with a constant temperature device, which is suitable for high-precision measurement of ultraviolet components in solar radiation or other artificial radiation sources, and adapts to the sensor by controlling the working temperature of the sensor. The invention relates to an outdoor environment, a wide geographical range, and the realization of ultraviolet radiation measurement required by high precision, and belongs to the technical field of ultraviolet radiation measurement. Background technique [0002] With the discovery of the atmospheric ozone hole, the measurement of the ultraviolet component of solar radiation has attracted increasing attention. Relevant departments not only provide the public with health and safety early warning services through the monitoring and forecasting of ultraviolet radiation, but also obtain relevant information on changes in the earth's ...

Problems solved by technology

[0003] Therefore, due to the limitation of the temperature characteristics of photoelectric devices, the current domestic ultraviolet radiation sensors are usually only suitable for low-precision measurement, or only suitable for laboratory environment applications.
