Abstract
A temperature sensing and limiting device is described for use in a radiant electric heater (8) incorporating at least one heating element (14). The device comprises an elongate tubular housing (1) adapted to at least partly traverse the heater so as to be heated externally by the heating element. A component (4) is provided within the housing and provides an electrical parameter which changes as a function of temperature. At least a thermal-sensing portion (11) of a thermally-responsive bimetallic cut-out device (10) is provided within the housing (1), the cut-out device being adapted to deenergize the heater (8) at a predetermined temperature.
