ABSTRACT:
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.
