ABSTRACT:
A temperature detecting device having rapid temperature sensing characteristics and with a fully protected temperature sensitive element. A transistor pellet potted in a resin casing having at least one thin wall is mounted in a metal protective tube in thermal contact provided through a small amount of filler material of high thermal conductivity. A heat collector is disposed around the protective metal tube in close thermal contact therewith. The edges of the heat collector are held in position against ribs formed on an insulating casing by engaging members of a protective ring which fit into corresponding notches formed in the upper portion of the ribs. Protrusions formed on the protective member prevent its rotation and removal hence making the device essentially tamperproof.
