Abstract: A current-to-pressure (I/P) converter provides an output pressure as a function of the magnitude of a variable input DC current. The I/P converter includes a pressure sensor which produces a feedback signal representative of the output pressure. Based upon the feedback signal and the magnitude of the input DC current, an electrical control signal is produced which controls a device for varying the output pressure. The I/P converter also includes a circuit for generating a time-varying signal which is sent back over the current loop wires through which the input DC current flows. The time-varying signal provides an indication of whether the I/P converter is functioning properly. This permits diagnosis of possible causes of control system malfunctions without having to inspect the I/P converter itself.

Abstract: An electric signal to pneumatic signal transducer 10 comprises a nozzle 12 that accepts an input pneumatic supply and expels a gas stream 20. A receiver 16 that is spaced from the nozzle is positioned to recover at least a portion of the gas stream. The recovered portion constitutes a pneumatic output signal. The position of a deflector 14 relative to the gas stream is controlled by an electric input signal to aerodynamically deflect the gas stream expelled from the nozzle. The aerodynamic deflection affects the magnitude of the portion of the gas stream recovered by the receiver in a manner having a known relationship to the electric input signal, thereby generating a pneumatic output signal responsive to the electric input signal.

Abstract: A modular transmitter has an outer housing with a wall forming an interior cavity in which a control module is inserted. The wall has one or more ports therein that are connected to pressure conduits. When the control module is fully seated, the ports align with internal passageways in the control module that lead to control components in the control module. The control module further has an electrical circuit supported on an end thereof that is toward the inner end of the cavity when the control module is inserted and the circuit has components that removably mate with further elements mounted on the end wall of the cavity. These connections may include electrical contacts, and also rotationally adjustable components that have set points and which are coupled to set point adjustment and control shafts that are accessible from the opposite side of the end wall from the cavity. The coupling to the rotatable shafts permits not only rotationally driving the circuit components, but also accommodates some offset or misalignment between the two parts. Preferably, the coupling is a hook and loop type fastener that has two portions which can be separated in an axial direction, and will easily recouple for driving.
