Abstract
A device is provided for digitally determining and safeguarding a thermal image including a processor connected to at least one sensor able to form a digital image of the thermal state of an apparatus, a random access memory containing the thermal image formed by the processor and a safeguard for storing, should there be a voltage cut, the instantaneous thermal image. The safeguard includes a programmable digital counter fed by a capacity curing power-cuts and equipped with a clock which modifies its counting state for the duration of the absence of voltage. The processor reads the state of the counter after restoration of the voltage.
