Abstract
An improved system for precisely measuring temperatures at remote locations using a microprocessor and resistance temperature detectors is achieved by providing means for pre-selecting a particular temperature range and using this temperature range information to generate a comparison level for determining the measured temperature. By employing the present invention, the fixed number of bits used to produce the temperature information output is concentrated over a limited range of temperatures, thereby achieving greater precision, since each information bit represents a much smaller number.
