1. The primary responsibility of a CCST Level I technician is to:
A. Design control strategies
B. Perform advanced system integration
C. Maintain, calibrate, and troubleshoot basic control systems
D. Approve safety instrumented functions
CCST Level I focuses on hands-on maintenance, calibration,
installation, and basic troubleshooting rather than system design or
engineering approval.
2. Which document provides step-by-step instructions for
maintaining equipment?
A. P&ID
B. Loop diagram
C. Standard Operating Procedure (SOP)
D. Instrument index
SOPs define standardized methods for operating and maintaining
equipment safely and consistently.
, 3. A pressure transmitter converts pressure into:
A. Mechanical energy
B. Hydraulic energy
C. Pneumatic energy
D. An electrical signal
Transmitters convert process variables into standardized electrical
signals such as 4–20 mA.
4. The most common analog signal used in industrial control systems
is:
A. 0–10 VDC
B. 1–5 VDC
C. 4–20 mA
D. 10–50 mA
The 4–20 mA signal is industry standard due to noise immunity and
fault detection.
5. A P&ID is primarily used to show:
A. Physical wiring paths
B. Process flow and control relationships
C. PLC logic
D. Instrument calibration data
P&IDs illustrate how process equipment and instrumentation interact.
6. Which device directly measures flow by detecting pressure drop?
A. Turbine meter
, B. Magnetic flowmeter
C. Orifice plate
D. Ultrasonic meter
Orifice plates create a differential pressure proportional to flow rate.
7. A thermocouple operates based on:
A. Resistance change
B. Capacitance variation
C. Seebeck effect
D. Inductive coupling
Thermocouples generate voltage due to temperature differences at
junctions.
8. Which temperature sensor typically provides the highest
accuracy?
A. Thermocouple
B. RTD
C. Thermistor
D. Infrared sensor
RTDs offer excellent accuracy and stability for industrial
measurements.
9. What is the primary purpose of grounding?
A. Improve signal speed
B. Provide safety and reduce electrical noise
C. Increase voltage
D. Prevent corrosion
