Abstract: A process fluid temperature measurement system includes a thermowell configured to couple to a process fluid conduit and extend through a wall of the process fluid conduit. A temperature sensor assembly is disposed within the thermowell and includes a first temperature sensitive element and a second temperature sensitive element. The first temperature sensitive element is disposed within the thermowell adjacent a distal end of the thermowell. The second temperature sensitive element is spaced apart from the first temperature sensitive element along a spacer having a known thermal conductivity. Transmitter circuitry is coupled to the first and second temperature sensitive elements and is configured to perform a heat flux calculation to provide a process fluid temperature output.

Abstract: A process fluid temperature transmitter includes a plurality of terminals, an excitation source, a measurement device, and a controller. The plurality of terminals is couplable to an RTD. The excitation source is operably coupled to the plurality of terminals and is configured to apply an excitation signal to the RTD. The measurement device is coupled to the plurality of terminals and is configured to measure a response of the RTD to the applied excitation signal. The controller is coupled to the excitation source and the measurement device. The controller is configured to perform an RTD resistance measurement by causing the excitation source to apply the excitation signal to the RTD and to cause the measurement device to measure the response of the RTD while the excitation signal is applied to the RTD. The controller is also configured to perform an RTD diagnostic by causing the excitation source to change application of the excitation signal and causing the measurement device to measure an RTD response to the changed excitation signal.

Abstract: A pipe diagnostic system includes a sensor capsule, measurement circuitry and a controller. The sensor capsule is configured to be coupled to an exterior surface of a pipe and has at least one temperature sensitive element disposed therein. The measurement circuitry is coupled to the sensor capsule and is configured to measure an electrical characteristic of the at least one temperature sensitive element and provide an indication of the measurement. The controller is coupled to the measurement circuitry and is configured to obtain a transmitter reference measurement and employ a heat transfer calculation with the transmitter reference measurement and the indication to generate an estimated process fluid temperature. The controller is further configured to obtain an indication of process fluid temperature and provide a pipe diagnostic indication based on a comparison of the estimated process fluid temperature and the obtained indication of process fluid temperature.

Abstract: A process fluid temperature estimation system includes a mounting assembly that is configured to mount the process fluid temperature estimation system to an external surface of a process fluid conduit. A sensor capsule has at least one temperature sensitive element disposed therein. Measurement circuitry is coupled to the sensor capsule and is configured to detect a characteristic of the at least one temperature sensitive element that varies with temperature and provide sensor capsule temperature information. A high temperature spacer has a known thermal conductivity and is configured to be interposed between the external surface of the process fluid conduit and the at least one temperature sensitive element. A controller is coupled to the measurement circuitry and is configured to obtain a reference temperature and employ a heat transfer calculation with the reference temperature, the sensor capsule temperature information and the known thermal conductivity of the high temperature spacer to generate an estimated process fluid temperature output.
