High-precision supply air temperature sensor (Supply sensor) designed for Carrier reefer containers. Installed directly in the airflow leaving the evaporator, this device continuously monitors the temperature of the cooled air entering the cargo compartment. The gathered data is transmitted to the controller for precise regulation of the refrigeration unit's capacity. It ensures a stable microclimate, preventing local overcooling or damage to temperature-sensitive cargo. The sensor housing features complete protection against moisture and condensation.
