    • A temperature indicator has a substrate (1) comprising several distinct juxtaposed zones (I to VIII), each being covered by a first thermosensitive material (A) and at least one second thermosensitive material (B, C) each of which reacts within a predetermined temperature range which is different for each zone but of constant scope. There is no overlapping of the temperature ranges of each material is within each zone. Each of the thermosensitive materials (A,B,C) has a portion of its range of reaction temperatures in common with a portion of the temperature range of one of the materials (A,B,C) of an adjacent zone. This overlapping is lower by one step in each of the temperature ranges. With three thermosensitive materials per zone, 24 sensing elements are available, which enables obtaining 18 times a single non-active sensor, namely 18 temperatures at the step resolution. The temperature is read at the side of the non-active zone.
    • 温度指示器具有包括几个不同的并置区域(I至VIII)的基底(1),每个区域被第一热敏材料(A)和至少一个第二热敏材料(B,C)覆盖,每个第二热敏材料(B,C) 温度范围不同,但范围不变。 每个区域内的每个材料的温度范围没有重叠。 每个热敏材料(A,B,C)的一部分反应温度范围与相邻区域的材料(A,B,C)之一的温度范围的一部分相同。 这种重叠在每个温度范围内降低一步。 每个区域使用三个热敏材料,可以使用24个感测元件,这样可以获得单次非活动传感器的18次,即步进分辨率下的18个温度。 在非活动区域的一侧读取温度。
