Abstract: A process fluid temperature estimation system includes a sensor capsule having a temperature sensitive element disposed therein configured to sense an external surface of a process pipe. The process fluid temperature estimation system includes measurement circuitry coupled to the sensor capsule and configured to detect a characteristic of the at least one temperature sensitive element that varies with temperature and provide sensor capsule temperature information and a controller coupled to the measurement circuitry, the controller being configured to obtain a reference temperature and employ a heat transfer calculation with the reference temperature and the sensor capsule temperature information to generate an estimated process temperature output. The process fluid temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to the external surface of the process pipe, wherein a portion of the mounting assembly is offset from the external surface of the process pipe.

Abstract: A process fluid multivariable measurement system is provided. The multivariable measurement system includes a thermowell configured to couple to a process fluid conduit and extend through a wall of the process fluid conduit. The multivariable measurement system also includes a temperature sensor assembly disposed within the thermowell, the temperature sensor assembly having at least one temperature sensitive element disposed therein. The multivariable measurement system also includes a pressure sensor assembly coupled to the thermowell, the pressure sensor assembly having at least one pressure sensitive element disposed therein. The multivariable measurement system further includes transmitter circuitry, communicatively coupled to the temperature sensor assembly and the pressure sensor assembly, configured to receive a temperature sensor signal from the at least one temperature sensitive element and responsively generate a temperature measurement output based on the temperature sensor signal. The transmitter circuitry is further configured to receive a pressure sensor signal from the at least one pressure sensitive element and responsively generate a pressure measurement output based on the pressure sensor signal.

Abstract: A temperature probe includes a sheath, a temperature sensitive element, and an insert. The sheath has a sidewall defining an interior space therein. The temperature sensitive element is disposed within the interior space of the sidewall and has an electrical characteristic that varies with temperature. The insert, which is formed of silicon carbide, is operably interposed between the sidewall and the temperature-sensitive element. A method of manufacturing a temperature probe is also provided. A temperature sensing system employing a temperature probe is also provided.
