Claim 0:
1. A system for monitoring of temperature trends for particles moving along a path of movement from a first position to a second position, the system comprising:
a sensor arrangement, a field-of-view of which is arranged in the path of movement of the particles to detect a signal related to the temperature of particles moving through said field-of-view, the sensor arrangement comprising at least one set of sensing elements detecting radiation emitted from the particles, each set comprising at least two sensing elements arranged to co-operate with mutually separated sensing zones along the path of movement of the particles; and
at least one processing device, which is arranged to:
receive signals from the sensor arrangement;
form signals from the at least one set of sensing elements into at least one pulse train of signal strengths when a particle moves through the field-of-view of the sensor arrangement; and
based on the relation between the signal strengths of this at least one pulse train, monitor changes over time in the temperature of different particles moving through the field-of-view of the sensor arrangement by monitoring changes over time in the wavelength distribution of the radiation emitted from the different particles.
