    Abstract: 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.

    Abstract: A process control system includes a transmitter having transmitter circuitry, a sensor, a remote sensing apparatus, a linkage and a slack take-up device. The sensor senses a process variable of a process fluid. The remote sensing apparatus communicates with the process fluid. The linkage communicates between the transmitter and the process fluid. The slack take-up device selectively adjusts a relative length of the linkage between the transmitter and the remote sensing apparatus.

    Abstract: A resonance frequency vibration power harvester (20) comprises an elongate body (36), a first vibration energy harvester device (42) and a weight (46). The elongate body (36) includes a first end (54), a second end (56) and an interior channel (65) extending through at least a portion of the elongate body (36) between the first end (54) and the second end (56). The second end (56) of the elongate body is for connecting to a vibration source (18) such that the first end (54) is cantilevered. The first vibration energy harvester device (42) is attached adjacent the first end (54) of the elongate body, and the weight (46) is joined to the interior channel (65) to adjust a resonant frequency of the elongate body (36).
