BTO2343 PIC CHAPTER 1

What is the main purpose of Process Measurement and Control?

• To monitor, regulate, and maintain desired process outcomes

• To replace human operator

• To increase energy consumption

• To design industry machinery

Which of the following is NOT a process variable.

• Temperature

• Flow rate

• Pressure

• Distance

What is the role of controller in process control?

• To measure the process variable

• To manually operate a system

• To record historical data

• To adjust the output based on feedback

What device is commonly used to measure pressure?

• Thermocouple

• Flow meter

• Manometer

• Tachometer

In a P&ID, the instrument labelled PT represent?

• Pressure controller

• Pressure transmitter

• FLow transmitter

• control valve

What type of control system uses feedback to regulate a process?

• Open-loop control

• Close-loop control

• Manual control

• Automated documentation control

What does a P&ID primarily represent in process measurement & control

• The layout of electrical wiring in a building

• The organizational chart of process operators

• The maintenance schedule for machinery

• A detailed diagram of piping, instrumentation, and control components

"I connect devices.I am represent by a dashed. Without me, a transmitter cannot convey its message." What am I?

A control valve adjusts the flow of fluid in a process system based on signals received from a controller.

True or False

Put the following steps of a close-loop control system in the correct order

• 2 > 4 > 5 > 1 > 3

• 2 > 4 > 1 > 5 > 3

• 2 > 5 > 4 > 1 > 3

• 2 > 4 > 5 > 3 > 1
