Abstract:
A diagnostic field device (12) for identifying a diagnostic condition in an industrial process (10) includes an infrared sensor array (100) having a plurality of infrared sensors arranged to sense infrared emissions (104) from a location (32) in the industrial process (10). Processing circuitry (102) processes outputs from the plurality of infrared sensors of the sensor array (100) and generates an infrared image. Diagnostic circuitry (24) compares processed outputs from at least two subsections of the infrared image and provides a diagnostic output based upon the comparison.
Abstract:
A sensor assembly with a sensing element sends a sensor signal from the sensing element to attached process transmitter over sensor connection wires. The sensor assembly has memory circuitry for storing information related to the sensor assembly and interface circuitry that provides for digital communication of the stored information with the attached process transmitter. This digital communication is sent over the sensor connection wires.
Abstract:
A thermowell assembly for measuring a process temperature includes an elongate thermowell (20) having a proximal end (70) and a distal end (72). A bore (74) extends between the two ends with the thermowell assembly configured to extend into a process fluid. An infrared sensor (24) detects infrared radiation from the distal end (70) through the bore (74) of the thermowell (20) and responsively provides a sensor output (26). A configuration is provided in which infrared radiation received by the infrared sensor (24) from a wall of the bore (76) is reduced and/or radiation received from the distal end (70) of the bore is increased.
Abstract:
An industrial process transmitter includes a transducer positioned to interact with an industrial process, display circuitry that displays a visual output to an operator, and control circuitry. The display can be selectively modified to provide the visual output at one of a plurality of orientations. The control circuitry is connected to communicate with the transducer and the display circuitry and receive an input regarding the orientation of the industrial process transmitter. In response to received input regarding the orientation of the industrial process transmitter, the control circuitry provides instructions to the display circuitry to modify the orientation of the visual output.
Abstract:
A display assembly includes a transparent cover piece (62), a display shroud (48; 248) having a contact structure (74; 274) arranged to face the transparent cover piece (62), an interface subassembly (32; 232) mounted on the display shroud (48; 248), an electronics board shroud (44) having a support member (82) and a connection feature (84), and a biasing member (46) operably engaged between the display shroud (48; 248) and the electronics board shroud (44). The connection feature (84) mechanically connects the electronics board shroud (44) to the display shroud (48; 248) while permitting axial displacement and rotation therebetween. The biasing member (46) rests on the support member (82) of the electronics board shroud (44), and the biasing member (46) is configured to urge the contact structure (74; 274) of the display shroud (48; 248) into physical contact with the transparent cover piece (62). The interface subassembly (32; 232) includes a display circuit (36) for providing a digital display and a touch circuit (34) for providing touch actuation at or near the digital display through the transparent cover piece (62).
