Abstract (en)
[origin: WO2018127357A1] The present invention relates to a system (1) for monitoring a predefinable temperature (Tmin/max), comprising a monitoring unit (2) comprising: a reference element (3), which reference element (3) consists at least partially of a material (10, 15), for which material (10, 15) at least one phase transition occurs at a phase transition temperature (Tph), which phase transition temperature (Tph) lies within the range of the predefined temperature (Tmin/max), for which phase transition the material (10, 15) remains in the solid phase; and a detection unit (4) which is designed to detect the occurrence of the phase transition using a change, in particular a sudden change, in at least one physical or chemical variable (G, Lref, Cref) characteristic of the reference element (3) and to generate a message as to whether the predefinable temperature (Tmin/max) has been exceeded or undershot. The invention also relates to a monitoring unit (2) and a detection unit (4) for use in a system (1) according to the invention and to a method for monitoring the predefinable temperature (Tmin/max) by means of a system (1) according to the invention.
