Abstract: Apparatus and associated methods relate to generating a temperature measurement signal based upon a weighted average of signals generated by a resistive temperature detector (RTD) and a thermocouple device. The thermocouple device includes first and second thermocouple junctions. The first thermocouple junction is thermally coupled to the RTD, and the second thermocouple junction is thermally isolated from the RTD. The thermocouple is configured to generate a signal indicative of a difference between first and second thermocouple junctions, which is substantially equal to the difference between the RTD and the second thermocouple junction due to the thermal coupling configuration. The RTD generates a signal indicative of a temperature of the RTD. A weighted sum of the first and second signals is indicative of a temperature of the second thermocouple junction, which responds rapidly to temperature fluctuations, due to its having a relatively small thermal mass compared with the RTD.

Abstract: A probe includes a probe head, a probe tip extending from the probe head and having a sensor in fluidic communication with a first fluid stream, a pressure channel extending into the probe tip through the sensor face with a pressure sensor that senses pressure in the pressure channel, and a temperature channel extending into the probe tip through the sensor face. The temperature channel including a temperature orifice disposed on the sensor face and at least one exit port distal from the sensor face. The temperature channel is parallel to and fluidly separate from the pressure channel and includes a temperature sensor that senses temperature in the temperature channel. The temperature channel directs fluid flow from the temperature orifice to the at least one exit port, thereby discharging fluid flow into a second fluid stream.

Abstract: A temperature sensor assembly for measuring a gas temperature in a gas flow stream includes a first substrate having a first surface configured to be connected to a thermally conductive structure in a gas path, a first temperature sensor mounted to the first substrate a first distance from the first surface, and a second temperature sensor mounted to the first substrate a second distance from the first surface. The second distance is less than the first distance. The first and second temperature sensors are arranged along a temperature gradient.

Abstract: A thermocouple assembly for use in a high-temperature gas path that includes a thermocouple. The thermocouple includes a first conductor and a second conductor, the first and second conductors formed of different materials and coupled to one another by junction, a metal sheath surrounding the first and second conductors wherein the metal sheath is substantially coaxial with the both the first conductor and the second conductor. The assembly also includes: a first termination electrically coupled to the first conductor; a second termination electrically coupled to the second conductor; a first connector configured to couple to the first termination; a second connector configured to couple to the second termination; and a housing configured to cover the first and second terminations and the first and second connectors.
