Question

All instruments and controlling elements in a control loop will have the same ____ on a P ID.

1) number
2) design
3) actuators
4) function

Answer 1

All instruments and controlling elements in a control loop will have the same function on a P ID.

Step-by-step explanation:

All instruments and controlling elements in a control loop will have the same function on a P ID. The function of instruments and controlling elements in a control loop is to measure and regulate variables such as temperature, pressure, or flow rate. In a PID control loop, the function of each element is to contribute to the overall control of the system and maintain it at the desired setpoint. For example, a temperature control loop may consist of a temperature sensor, a controller, and an actuator that adjusts the heat source. Each element has a specific function in maintaining the desired temperature.
