1. A process fluid temperature calculation system comprising:

  • a first temperature sensor disposed to measure an external temperature of a process fluid conduit;

    a stem portion having a known thermal impedance;

    a second temperature sensor spaced from the first temperature sensor by the stem portion;

    measurement circuitry coupled the first and second temperature sensors; and

    a microprocessor coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to calculate a process fluid temperature output using a heat flux calculation.
