Sample questions
01What is the primary purpose of instrumentation in industrial processes?
- A.To store process data for regulatory archiving only
- B.To measure, monitor, and control process variables
- C.To generate electrical power for the plant
- D.To provide structural support for pipework
Why: Instrumentation systems are designed to measure, monitor, and control critical process variables like temperature, pressure, flow, and level.
02Which of the following is NOT a typical process variable in instrumentation?
- A.Pressure
- B.Flow rate
- C.Temperature
- D.Colour
Why: While colour can be measured in some specialised applications, it's not a typical process variable. Standard variables are temperature, pressure, flow, and level.
03What does SCADA stand for?
- A.Signal Control And Digital Automation
- B.Supervisory Control And Data Acquisition
- C.System Control And Data Acquisition
- D.Standard Control And Data Analysis
Why: SCADA stands for Supervisory Control And Data Acquisition, a system for remote monitoring and control of industrial processes.
