The Development of a Thin‐Film Silicon Carbide Thermistor Array for Determining Temperature Profiles in an Evaporating Liquid Film

A linear thin‐film array of silicon carbide thermistors has been developed to measure temperature profiles near the contact line of an evaporating liquid meniscus. The array consists of 80, square silicon carbide thermistors on a 3 in. diam single crystal of silicon. The devices are spaced at 50, 250, and 1000 μm intervals along the wafer. Temperature data are obtained through the use of an external electronic data acquisition system. This arrangement enables an accurate evaluation of the heat flux occurring in an evaporating thin liquid film, and it should also be suitable for temperature measurements in many other situations.
