What is the term for the target value that the process should maintain?

The term for the target value that a process should maintain is known as the setpoint. In control systems, the setpoint represents the desired value of a process variable that operators aim to achieve and maintain through various control strategies. For instance, in a temperature control system, the setpoint would be the temperature that the system is designed to maintain. The control system uses this setpoint to determine the necessary adjustments needed in response to any deviations from this value, ensuring the process operates within its intended parameters.

Control device refers to the equipment that measures and adjusts the process variable but does not define the target itself. Transmitter refers to a device that converts physical quantities into a signal for monitoring or controlling but is not the target value. Measurement simply refers to the act or process of obtaining data about the process variable without indicating desired values.
