Thermal sensors in Temperature control in deep freezers, coolers, heaters, and aquariums
Thermal Reed Switches are used in a wide range of white goods applications, either to take certain action like switching on a cooling circuits or to trigger alarms. Due to their clear on and off signal and high reliability, they are used in place of bimetallic strips, thermistors and thermostats for over-heat protection or precise temperature switching. In deep freezers, coolers and heaters, the temperature needs to be maintained within a precise window. Thermal reed sensors can be designed having windows as small as 2°C up to 10°C, and can switch up to 60W directly. The sensor can control the switching on and switching off points of compressors in deep freezers and fans in coolers. Thermal reed switches can also be used in aquariums by switching heaters in the water to keep the temperature exactly between 25°C and 30°C.
