Abstract
An apparatus and method for measuring, collecting, and processing the temperatures of a number of hot junctions in a thermocouple sensor array simultaneously comprises means for measuring the temperature of one or more reference junctions and means for collecting, processing, storing, and transmitting data collected from an array of thermocouple temperature sensors. The measured temperature(s) of the one or more reference junctions is used to correct the measured voltage in each of a plurality of thermocouple circuits to obtain accurate hot junction temperature measurements. The apparatus and method are particularly useful for collecting and processing temperature data from various locations within engines such as turbine, rocket, and internal combustion engines.
