Fast precision thermometer with one or more channels comprises one or more calibrated thermistors in a potentiometer circuit, whose output is digitized and subjected to processing using a Steinhart-Hart equation

摘要

Temperature measurement device comprises one or more calibrated thermistors in a potentiometer circuit. The output of the circuit is temperature-dependent voltage that is connected to an analogue to digital converter. The digital measurements are processed in a computer or microcontroller using a Steinhart-Hart equation to yield individual parameters and from these, the temperature.
