ABSTRACT:
A temperature sensing apparatus (10) adapted for sensing the temperature of a food item or the environment in an oven includes a body (12) which encloses a chamber (38). The chamber houses an indicator (22) which is viewed through a frangible glass pane (34). Slight amounts of water vapor that infiltrate into the chamber during washing are vented when the apparatus is placed in a high temperature environment. A resilient member (70) having a lip portion (74) is normally in abutting relation with an outer case wall surface (48). When pressure builds in the chamber during heating due to rapid expansion of the water vapor, the pressure applied through an opening (40) acts against the lip portion of the resilient member. When the pressure rises to a sufficient level, it deforms the lip portion away from the adjacent wall surface whereby pressure is relieved to atmosphere. The pressure in the chamber is relieved before it reaches a level that may fracture the frangible glass pane or cause other damage. When the pressure falls, the lip portion returns to its initial configuration again closing the chamber.
