    • A temperature sensor for radiant heating units with a heating coil disposed in a cup includes a tube with a first end connected to a housing of a switch with a movable contact cooperating with stationery contacts in the housing. A two-section rod, which extends into the housing of the switch and operates the movable contact, is supported inside the tube. The tube and the rod have different thermal expansion coefficients. To prevent a shift in the switching point, the section of the rod that operates the contact terminates outside the hollow space of the cup, and the temperature-induced length changes of this section and of the housing are matched to each other.
    • 用于辐射加热单元的温度传感器,其具有设置在杯中的加热线圈,其包括:管,其第一端连接到具有与壳体中的文具触点配合的可移动触点的开关的壳体。 延伸到开关的壳体中并操作可动触头的两段杆被支撑在管内。 管和杆具有不同的热膨胀系数。 为了防止切换点的移动,操作接触的杆的部分终止于杯的中空空间外部,并且该部分和壳体的温度引起的长度变化彼此匹配。

    • A thermal cut-out device for a radiant heater comprises a probe-type thermally responsive assembly (2), at least a part of which is coated with and/or is surrounded by a radiation reflective material. The probe-type assembly may comprise a first element (3) in the form of a rod of material having a relatively high coefficient of thermal expansion and a second element (4) in the form of a tube of material having a relatively low coefficient of thermal expansion. The rod may be coupled to a snap-acting switch assembly (1). One or both of the first and second elements may be coated with or surrounded by the radiation reflective material. Alternatively the tube which surrounds the first element may be made of the radiation reflective material. The radiation reflective material may comprise a metal such as gold or a suitable element from Group VIII of the Periodic Table or may comprise a high temperature resistant particulate material such as aluminium oxide, magnesium oxide, titanium dioxide or tin oxide.
    • 用于辐射加热器的热切割装置包括探针型热响应组件(2),其至少一部分被辐射反射材料涂覆和/或被辐射反射材料包围。 探针型组件可以包括具有相对高的热膨胀系数的材料棒形式的第一元件(3)和具有相对较低系数的材料管形式的第二元件(4) 热膨胀。 杆可以联接到快动开关组件(1)。 第一和第二元件中的一个或两个可以被辐射反射材料涂覆或被辐射反射材料包围。 或者,围绕第一元件的管可以由辐射反射材料制成。 辐射反射材料可以包括诸如金的金属或周期表第VIII族的合适元素,或者可以包括耐高温的颗粒材料,例如氧化铝,氧化镁,二氧化钛或氧化锡。
