Sample questions
01What is the primary purpose of instrumentation in industrial processes?
- ATo store process data for regulatory archiving only
- BTo measure, monitor, and control process variables
- CTo generate electrical power for the plant
- DTo 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?
- APressure
- BFlow rate
- CTemperature
- DColour
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?
- ASignal Control And Digital Automation
- BSupervisory Control And Data Acquisition
- CSystem Control And Data Acquisition
- DStandard Control And Data Analysis
Why: SCADA stands for Supervisory Control And Data Acquisition, a system for remote monitoring and control of industrial processes.
