サーマル検出装置。Consists of a heat generating resistance element and a thermal reed switch.
In a device configuration in which a thermal reed switch heated above a certain temperature due to the heat generated by the resistance element operates to sense temperature, the switch contact closes and outputs a detection signal. Thermal detection is characterized in that a first thermal reed switch that operates and a second thermal reed switch that operates at a lower temperature than the temperature that the first thermal reed switch senses are arranged in close proximity. Device.
