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.

Abstract: A process transmitter includes a transmitter housing and a liquid detector coupled to the transmitter housing. The liquid detector includes a temperature sensor configured to generate signals indicative of a presence of liquid within the transmitter housing. The process transmitter also includes a controller coupled to the liquid detector configured to receive the generated signals, determine the presence of liquid within the transmitter housing based on the received signals, and generate an output indicative of the determined presence of liquid within the transmitter housing.

Abstract: An explosion-proof thermal imaging system is provided. The system include an explosion-proof housing having a window that is configured to allow thermal radiation therethrough. An infrared camera is positioned within the explosion-proof housing and is disposed to receive and image thermal radiation that passes through the window. An emissivity target is disposed within a field of view of the infrared camera, but on an opposite side of the window from the infrared camera. A temperature sensor is operably coupled to the infrared camera and is configured to provide an indication of temperature proximate the emissivity target.
