_____________________ employs two controllers, where the output of one controller becoming the remote set point of another.

Cascade control is characterized by ,

The advantage of cascade control system is ,

Split range control is characterized by ,

The output signal of _____________________ is divided between two final control elements. ,

The disadvantage of split range control system is .

In cascade control, the primary controller is also known as ,

_______________ is used to predict the future behavior of error based on the present values,

Cascade control is used when two fluids must be mixed together in a specific ratio.

Feedforward controller avoids the slowness of the feedback controller.

Split controller is a special type of feed forward controller.

Multivariable controller is used in distillation and fractionation towers.

PID controller is widely used in open-loop control.

In cascade control system, the primary controller is also known as Mixed controller.

In cascade control system, the secondary controller is also known as Slave controller.

The disadvantage of cascade control system is use single controller output to control all manipulated variables.

Ratio control is used to ensure that two or more flows are kept at the same ratio even if the flows are changing.

Ratio control system is useful for blending raw materials to make a final product.

The target value of the process variable that is desired to be maintained is called ______________________.

A collection of instruments that work together to control a process is known as ______________________.

The initial measurement device in a control loop that can detect the process variable is called ______________________.

A device that is designed to convert the signal produced by a sensor into the standardized instrumentation signal that can be transmittable through the control loop is called ______________________.

______________________ is the major element in a control loop and it maintain process variable at a desired value.

The last active device in the control loop is ______________________.

______________________ in which the control action from the controller is dependent on feedback from the process

Sensors are also known as Primary elements.

Control Value is an example of primary element.

Orifice plate is a primary element that can detect the level.

Final control element is the initial measurement device in a control loop.

Transmitter is the major element in a control loop.

Final control element is the last link in the control loop.

Transmitter sends 4-20mA signal which indicates the process variable parameter and acceptable to the controller

Controller is a device that converts the signal produced by a sensor into a standardized instrumentation signal that can be transmittable through the control loop.

Transducer is a device that converts a signal in one form of energy to a signal in another that must be read by the next element in the control loop.

Identify the figure given below

The initial measurement device in a control loop that can detect the process variable is called __________________.

__________________ in which the control action from the controller is dependent on feedback from the process.

__________________ measure disturbances and take corrective action before it affects the process.

__________________ is designed to increase the output signal, when the input signal increases.

__________________employs two controllers, where the output of one controller becoming the remote setpoint of another.

__________________ involves a selection between two or more controller output signals, where only one controller at a time gets the opportunity to exert control over a process.

In PID control, __________________ is used to predict the future behavior of error based on the present values.

_________________ is used to prevent actions taking place until pre-defined criteria have been satisfied.
