ICM 805

Referring to the picture shown, What kind of controller is being shown?

• Pressure controller

• Level controller

• Temperature controller

• Flow controller

What is the use of automatic control?

• reduce manpower

• reduce costs

• make the process operate more uniformly

• decrease maintenance

What does room temperature in a home heating system represent? *

• process variable

• setpoint

• inferred variable

• manipulated variable

Which control system does not have a stability problem?

• open loop system

• closed loop system

• level control system

• sequence control system

Which of the following controllers has maximum offset?

• P-D controller

• P-controller

• P-I controller

• P-I-D controller

Referring to the picture shown, What kind of controller is being shown?

• flow controller

• level controller

• temperature controller

• pressure controller

What is a the main equivalent of a controller in terms of a functionality?

• amplifier

• clipper

• sensor

• comparator

What is the main requirements for a process control element for a proper feedback?

• measure process

• measure set point

• measure error

• measure comparator

When a process controller is in the “automatic” mode,

• the output responds to changes in the process variable

• the control valve will fail closed

• the process variable cannot deviate from setpoint

• the controller will automatically generate alarms

What does a basic control loop will consist of?

• signal converter, resistor, knob, and control valve

• transducer, valve packing, hex-head wrench, and tubing

• transmitter, controller, I/P transducer, and control valve

• control valve, microprocessor, terminal block, and cables
