る簡易火災予知器。 The surface of a conductor of arbitrary length that melts at around 150°C is coated with an electrical insulation coating at a temperature higher than the temperature at which the conductor (wire) melts, or the temperature at which the conductor melts is several degrees Celsius to several tens of degrees above the melting temperature. A simple fire predictor consisting of an electrically insulating tube that melts or softens at high temperatures, insulating the conductor, a transistor, and an alarm.
