Word forms: (regular plural) control loops
(Mechanical engineering: Control, instrumentation and metrology)
control , control
The furnace temperature control loop consists of a thermocouple, a program to compare the measured temperature with the
required one, and a heater which switches on if the temperature is too low. A good example of a control loop is the action taken when adjusting hot and cold valves to maintain the water at a
desired temperature. A control loop is a series of control operations, including measuring an output, establishing what
the output should be, and taking action to correct it.
