ABSTRACT:
A device for measuring and signaling the internal temperature of a container. The device includes an energy source, an informing device electrically connected to the energy source, and a bimetallic element electrically connected to the energy source. The bimetallic element is configured to deform based upon a variation in the internal temperature of the container. The device further includes a selector configured to provide for the selection of a predetermined temperature valve and having a conductive portion electrically connected to the informing device. The bimetallic element is configured to contact the conductive portion when the internal temperature of the container reaches the predetermined temperature value, thereby creating a closed electrical loop that actuates the informing device.
