The typical industrial process control system is operated by one or more final control elements, such as valves, adapted to govern the supply of fluid to the process. A pneumatically-operated diaphragm type valve is the final control element for this process. A pneumatic transmitter manually settable by an operator is used to actuate this valve. This transmitter functions to transmit air to the final control element at a pressure level within a desired process control range. A manual transmitter of this type generally includes a pneumatic relay to increase the air handling capacity of the system. Pneumatic relays are in widespread use for controlling valves, actuators and the like. A pneumatic relay supplies a controlled output pressure to a load or utilization device, such as an actuator or a piston, in response to an input signal, a pressure or a force. Pneumatic relays are required to function in either a proportional or an on/off mode. In the proportional mode, a pressure output that is proportional to a pressure or force input is developed. In the on/off mode a constant pressure output, usually equal to the supply pressure, is provided for a given range of pressure or force inputs.
