ABSTRACT:
A digital temperature indicating system which enables a relatively inexpensive thermistor sensor to be used to obtain highly accurate temperature measurements over a number of relatively narrow temperature ranges, and to obtain acceptable temperature accuracy over an extended temperature range. The thermistor controls a bridge. The bridge produces an analog signal when the thermistor causes the bridge to become unbalanced from a null point as the thermistor senses different temperatures. The analog signal from the bridge is converted into digital signals which address memory locations in a programmable read-only memory (PROM) for both scaling and linearizing purposes. The resulting output signals from the PROM are used to control a display unit which displays the temperature readings.
