Abstract

In this paper, we fabricated fuel shortage detecting sensor, utilizing NTC thermistor concerned with Mn-Ni-Co system. We would be obtained B constant value of 1930∼2080 and resistivity 387∼430(ohm-cm) additive Bi$_2$O$_3$0∼0.5 wt% to Mn$_3$O$_4$:9wt%, Co$_3$O$_4$:61wt%, NiO:28wt% under 1150∼1250$^{\circ}C$ of sintering temperature. In sensor, we obtained characteristics, which we want, in resistance range 850∼l150$\Omega$, B constant 2000${\pm}$5%. we can see 15 multiplied differences between gasoline and heat dissipation coefficient of air condition.
