Abstract
A method of generating a temperature measurement for a batch or a continuous stream of material. The method includes providing a particle having a signal that changes at a pre-determined temperature; inserting the particle into the batch or continuous stream; and detecting a signal change from the particle to thereby generate a temperature measurement for the batch or continuous stream. A suitable system for use in carrying out the method is also described.

A method of generating a conservative time-temperature measurement for a batch or a continuous stream of material, the method comprising:
- (a) providing a particle that emits a first signal at temperatures below a pre-determined temperature and emits a second signal at temperatures above the pre-determined temperature;
- (b) inserting the particle provided in step (a) into the batch or continuous stream;
- and
- (c) measuring the time spent by the particle above the pre-determined temperature by detecting the second signal continuously in a process stage to thereby generate a conservative time-temperature measurement for the batch or continuous stream.
A method of generating a conservative time-temperature measurement for a batch or a continuous stream of material, the method comprising:
- (a) providing a plurality of particles, each particle emitting a first signal at temperatures below a different pre-determined temperature and emitting a second signal at temperatures above the different pre-determined temperature;
- (b) inserting the particles provided in step (a) into the batch or continuous stream;
- and
- (c) measuring the time spent by the particles above the pre-determined temperature by detecting the second signal continuously in a process stage to thereby generate a conservative time-temperature measurement for the batch or continuous stream.
