, 1. Which four variables constitute the primary process variables in
industrial instrumentation?
A. Voltage, current, resistance, power
B. Speed, torque, vibration, humidity
C. Pressure, level, flow, temperature
D. pH, conductivity, density, viscosity
Correct Answer: C
Rationale: The NCCER Level 1 curriculum identifies pressure, level, flow, and
temperature as the four primary measured process variables in industrial
instrumentation. These variables are the foundation of process control and
are measured and controlled in virtually every industrial process.
2. Instrumentation is best defined as:
A. Carpentry tools and construction equipment
B. The science of automated measurement and control of process variables
C. Electrical power distribution systems
D. Manual valve operation only
Correct Answer: B
Rationale: Instrumentation encompasses sensors, transmitters, controllers,
and final elements used to measure and automatically control industrial
processes. It involves the application of measurement and control principles
to monitor and regulate process variables such as pressure, temperature,
flow, and level.
3. The three essential elements of a basic feedback control loop are:
A. Pump, motor, tank
B. Measurement, comparison/controller, correction/final element
C. Wire, conduit, junction box
D. Input, output, ground
