    Abstract: A process transmitter (12) for sensing a process variable of a process fluid includes a process sensor (30), transmitter circuitry (40), a transmitter housing (38) and a transmitter mounting component (33, 44A, 44B). The process sensor (30) senses the process variable of the process fluid and the transmitter circuitry (40) processes a signal from the process sensor (30). The transmitter housing (38) receives the process sensor (30) and transmitter circuitry (40), and the transmitter mounting component (33, 44A, 44B) isolates the sensor (30) or the transmitter circuitry (40) from the process fluid or external environment. The mechanical integrity sensor (46A, 46B, 52A, 52B) validates assembly of the transmitter housing (38) and transmitter mounting component (33, 44A, 44B).

A controller (112) receives an indication of differential pressure and generates a control signal to an actuator that actuates the closure mechanism (12, 106). The closure mechanism (12, 106), differential pressure sensor (20, 22; 120, 122) and controller (112) create a closed-loop flow controller in a single process device (10, 100).

    Abstract: A process transmitter for measuring a process variable in an industrial process comprises a gauge pressure sensor, an excitation source and transmitter circuitry. The gauge pressure sensor measures a pressure difference between a process fluid and a reference volume, and generates a pressure sensor signal representing the pressure difference. The excitation source generates a pressure pulse within the reference volume to influence generation of the pressure sensor signal. The transmitter circuitry is connected to the gauge pressure sensor to provide an output related to a change in the pressure sensor signal due to the pressure pulse.
