Traffic weather stations are usually composed of meteorological transmitters, collectors, power supply systems, radiation-proof ventilation covers, all-weather protection boxes and meteorological observation brackets, communication interfaces and peripheral equipment. The transmitters used in weather stations will involve temperature and humidity transmitters, atmospheric pressure transmitters, wind speed and direction transmitters, etc. Real-time monitoring of temperature, humidity, air pressure, wind direction, precipitation and other factors in the highway environment.
The temperature and humidity transmitter used in the weather station is an outdoor temperature and humidity transmitter, which is equipped with a 5-layer standard radiation cover (light louver box), and the radiation shield protects the sensor from rain, sun and ultraviolet radiation, and can normally sense the surrounding temperature and humidity environment. The outdoor temperature and humidity transmitter protective cover is designed with special materials to prevent sunlight radiation, rain, and can be increased or decreased in height at will. The working temperature range of the outdoor type temperature and humidity transmitter is between -40°C~60°C. The outdoor temperature and humidity transmitter also has the characteristics of low drift, fast response, long service life and strong anti-interference ability.
During the installation and use of outdoor temperature and humidity transmitters, it is necessary to ensure that the transmitter should be placed vertically to avoid rainwater backflow due to inclination. Outdoor temperature and humidity transmitters should not be installed in areas where heat transfer is easy and will directly cause a temperature difference with the area to be measured, otherwise the temperature and humidity measurement will be inaccurate. At the same time, the temperature and humidity transmitter should be kept away from high-power interference equipment as much as possible, so as not to cause inaccurate measurement, such as frequency converters, motors, etc.
