150. In a closed-loop process control system featuring negative feedback, what is the function of the error detector within the controller?

The error detector computes the product of the measured value of the controlled variable and the desired value (setpoint).
The error detector computes the difference between the measured value of the controlled variable and the desired value (setpoint).
The error detector computes the quotient of the measured value of the controlled variable and the desired value (setpoint).
The error detector computes the sum of the measured value of the controlled variable and the desired value (setpoint).
