Oct 10, 2017 PDF Document 3613ARS Digital Temperature RH Sensor with Aspirated Radiation Shield - Product Manuals
Thank you for purchasing a Digital Temperature/RH Sensor with Aspirated Radiation Shield (ARS). To ensure temperature and humidity sensors output accurate meteorological data, they are usually housed inside a radiation shield. However, solar radiation of the surface of the shield will lead to the interior being heated above air temperature. Under outdoor conditions, natural airflow is usually sufficient to ensure air temperature readings are accurate. But when the sensor is located indoors (such as in a greenhouse), the air is often stagnant, which leads to insufficient circulation. The solar-powered fan forces air through the shield to ensure that the sensor is measuring ambient air.
