Abstract: Heat resistant sensors equipped with any of a variety of transducers for measuring any of a variety of properties of fluids are constructed with components comprising materials that can withstand very high temperatures. Some embodiments of the sensors include a base comprising non-conductive ceramic material, and some embodiments of the transducers include conductive ceramic materials with resistivities that vary as a function of temperature. Some embodiments of the sensors also include electrical conductors comprising electrically conductive ceramic material or electrical conductors comprising an electrically conductive refractory metal on the base. Other embodiments of the transducers include a capacitor constructed of materials that can withstand very high temperatures.
