Abstract
Integrated transmitters and controllers for use in monitoring process variables. A transmitter and controller for monitoring and controlling a process variable in a process control loop comprises a transmitter for producing a digital signal indicative of the process variable's state, and a digital controller supplied with the digital signal from the transmitter responsive to the digital signal, and further interfaced in a process control loop for controlling the process variable in response to the digitally communicated signal from the transmitter. Integrated transmitters and controllers described herein simplify installation and maintenance of industrial process control systems and place the controller functions at the process variable, thereby increasing control system efficiency.
