Abstract :
A negative temperature-coefficient thermistor based on a tin oxide-titanium oxide solid solution has been developed. In pellet or bead form, the sintered device is stable at 1800°F. Typical room temperature resistance is above 150 megohms while resistance at 1800°F is less than 50 ohms. This strong response provides a solid-state ON/OFF sensor for switching systems in major appliances, industrial flame detection devices, and other sensing applications in high ambient temperatures. Specific considerations in the application of these devices are discussed.
