Abstract: A pipe diagnostic system (200) includes a sensor capsule (206), measurement circuitry (228) and a controller (222). The sensor capsule (206) is configured to be coupled to an exterior surface of a pipe (100) and has at least one temperature sensitive element disposed therein. The measurement circuitry (223) is coupled to the sensor capsule (206) 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 (222) is coupled to the measurement circuitry (223) and is configured to obtain a transmitter reference measurement (502) and employ a heat transfer calculation (506) with the transmitter reference measurement and the indication to generate an estimated process fluid temperature. The controller (222) is further configured to obtain an indication of process fluid temperature and provide a pipe diagnostic indication (512) based on a comparison of the estimated process fluid temperature and the obtained indication of process fluid temperature.

Abstract: A process variable transmitter (200) connects a serial bus (232) to an accessory load. A supply limiter circuit (234) provides a first supply current limit and provides a stored energy output (236). A recessive driver circuit (238) draws a drive current from the stored energy output (236) and couples the drive current to the serial bus (232). The recessive driver circuit (238) provides a drive current limit. A dominant driver circuit (242) has a dominant state in which it conducts the drive current, and an inactive state in which the drive current is available to the accessory load.

Abstract: A process fluid temperature estimation system (200) includes a mounting assembly (202) configured to mount the process fluid temperature estimation system (200) to an external surface (116) of a process fluid conduit (100). A sensor capsule (206) has at least one temperature sensitive element (254) disposed therein. Measurement circuitry (228) is coupled to the sensor capsule (206) and configured to detect an electrical characteristic of the at least one temperature sensitive element (254) that varies with temperature and provide sensor capsule temperature information. A controller (222) is coupled to the measurement circuitry (228) 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 process fluid conduit to generate an estimated process fluid temperature output. The reference temperature is obtained from a reference temperature source selected from the group consisting of: a terminal temperature sensor (232), process communication, an electronics temperature sensor (234), an external ambient temperature sensor (246), and an estimation based on known thermal properties.
