This material s saturation magnetic ux density decreases as the temperature increases, and it turns into a paramagnetic substance at the Curie temperature. Structures and Principles of Operation Thermal Reed Switches (TRS) are temperature-sensing switches composed of a magnet and a temperature-sensing soft ferromagnetic substance called Thermorite. This materials saturation magnetic flux density decreases as the temperature Temperature sensing ferrite Thermorite increases, and it turns into a paramagnetic substance at its Curie temperature. Our self-developed Themorite is temperature sensing ferrite utilizing Curie-temperature, where ferrites lose its magnetic property. Thermorite properties Thermorite changes its magnetic property rapidly at Curie-temperature. Features of Thermorite as temperature sensing material. Thermorite changes its magnetic property rapidly at its Curie temperature, providing quick response times. (1) Curie-temperature do not vary as time advances, because it depends on compounding ratio. The Curie temperature of Thermorite does not vary with time, as it is based on a compounding ratio. (2) Arbitrary shape available as ceramics. Thermorite is stable against moisture and hazardous gas. (3) Stable against moist or hazardous gas.

The reeds are switched on or off Inactive gas Contact Fe-Ni alloy reed by magnetic field of permanent magnet or magnet coil. Long lifetime, High environmental resistance because of protected contact by glass encasing. N S Reeds in glass tube become magnetized with SS NN NN magnetic field, and then two reeds contact and KEMET Electronics Corporation KEMET Tower One East Broward Boulevard SE0201 TRS 11/2/2021 2 SS connect each other (switch on).
