    摘要: A process control system includes a process sensor, an inclination sensor and transmitter circuitry. The process sensor senses the process variable of a process fluid and the inclination sensor senses the orientation of the transmitter. The transmitter circuitry produces an output based on the sensed process variable and the sensed orientation.

    摘要: A process transmitter includes a hydraulic system with a fill fluid for transmitting pressure from a process fluid to a pressure sensor. The fill fluid contains hydraulic fluid and a self-activating stop-leak composition for preventing loss of fill fluid caused by leaks in the hydraulic system.

    摘要: A redundant pressure transmitter for redundantly measuring pressure of a process fluid comprises a transmitter housing, transmitter circuitry, a remote seal assembly including a first pressure sensor, and a second pressure sensor positioned in the transmitter housing. The remote seal assembly also comprises a remote seal flange, a communication system and a capillary tube. The remote seal flange communicates with the process fluid and the first pressure sensor senses the process fluid pressure at the remote seal flange. The communication system relays output of the first pressure sensor to the transmitter circuitry, and the capillary tube communicates the process fluid pressure to the transmitter housing via a fill fluid, where the second pressure sensor senses the pressure of the process fluid through the fill fluid.

    摘要: An instrument loop adapter includes an interface portion that is configured to couple to a header of a miniature process variable transmitter. In some embodiments, the interface portion includes a standardized cable output portion. In other embodiments, a cable portion is coupled to the interface portion. Additional functionality is provided in the interface portion, the cable portion or both portions. The additional functionality can include circuits that provide features not present in the process variable transmitter.
