Abstract: An industrial process vessel insulation monitoring system for monitoring an insulated section of a process vessel containing a process material includes one or more condition sensors and a controller. The condition sensors are configured to sense at least one environmental condition, such as temperature, humidity, moisture level, and/or chemical composition, and generate condition outputs that are indicative of the corresponding sensed condition. The controller is configured to detect at least one section condition relating to the insulated section based on the condition output, and generate condition information relating to the at least one detected section condition. Examples of the section conditions include a thermal resistance of an insulation of the insulated section, damage or degradation to an insulation of the insulated section, corrosion of the process vessel at the insulated section, conditions that promote corrosion of the process vessel, and moisture intrusion to the insulation.

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.

Abstract: A pressure transmitter includes a housing and a pressure sensor having an electrical characteristic that varies with applied pressure. The pressure sensor is configured to generate a sensor signal indicative of process fluid pressure. A transmitter isolation diaphragm is configured to couple to a process barrier seal to convey pressure to the pressure sensor. A flange is coupled to the transmitter isolation diaphragm. The flange includes at least one gas pathway extending inwardly from an outer diameter of the transmitter isolation diaphragm. Electronics are coupled to the pressure sensor to receive the sensor signal and to generate an output indicative of the pressure.

Abstract: A remote seal system includes a remote diaphragm having a first side configured to be exposed to a process fluid. A conduit is coupled to the remote diaphragm and includes a fill fluid in fluidic communication with a second side of the remote diaphragm. A temperature sensor is thermally coupled to the conduit and configured to sense a temperature of the fill fluid. In one alternative example, a remote sensing assembly includes a flexible elongate conduit having a first end coupled to a remote diaphragm in fluidic communication with a process fluid and a second end extending a length from the first end to a process fluid pressure transmitter. A substantially incompressible fill fluid is disposed within the flexible elongate conduit. The process fluid pressure transmitter is configured to generate an output value indicative of pressure in the process fluid based on a corresponding pressure in the fill fluid. A temperature detector is coupled to the flexible elongate conduit and is configured to provide a signal indicative of an average temperature of the fill fluid along the flexible elongate conduit. A compensation system calculates a thermal expansion value based on the average temperature and adjusts the pressure signal based on the thermal expansion value.

Abstract: An industrial process field device includes an active component, a latching relay, a controller, a relay drive, and a reset circuit. The active component may be a sensor configured to sense a process parameter, or a control device configured to control a process of the industrial process. The controller is configured to generate a switch signal, and the relay drive is configured to set the latching relay in one of a set state and a reset state based on the switch signal. The reset circuit is configured to set the latching relay to the reset state in response to an interruption of electrical power to the relay drive.
