Abstract
A gas flow temperature probe includes a sensor device for sensing the ambient gas cooling rate and temperature; a prenormalizer circuit responsive to and remote from the sensor device for detecting gas cooling rate and temperature signals from the sensor device and for providing calibration data unique to the probe for normalizing the detected gas cooling rate and temperature to generate a normalized gas flow and temperature sensed by the probe; and an elongated flexible cable interconnecting the sensor device and the prenormalizer circuit for transmitting the ambient gas cooling rate and temperature signals from the sensor device to the prenormalizer circuit; a gas flow temperature monitor circuit includes a multiplexer circuit for real time sampling of a number of probes; a scheduler circuit for defining the sampling rate; and a normalizer circuit for combining the gas cooling rate and temperature signals and the calibration data from the prenormalizer circuit for each probe and generating normalized gas flow and temperature sensed by each probe.
