Abstract : The present invention provides a novel temperature warning device comprising only a tungsten filament lamp, a thermistor sensor device and a voltage source all in series circuit relation, which system when properly designed (i.e., the thermal time constant of the lamp exceeds that of the sensor) provides a visible signal which is a function of the temperature of the sensor's housing. The invention relates generally to temperature sensor and warning systems and more particularly to systems for determining when the temperature of an environment has exceeded a specified predetermined maximum.
