100% Pass
What does PID stand for in control systems?
✔✔PID stands for Proportional, Integral, and Derivative, which are the three components used to
calculate the control output in automated systems.
How does a differential pressure transmitter function?
✔✔A differential pressure transmitter measures the difference in pressure between two points in
a system, often used to determine flow rates or liquid levels.
What is the purpose of a data acquisition system?
✔✔A data acquisition system collects, analyzes, and stores data from various sensors and
instruments for monitoring and decision-making.
What is a control valve, and why is it used?
✔✔A control valve regulates the flow of fluids in a system, helping to maintain desired
operating conditions.

,How can environmental conditions impact instrument performance?
✔✔Environmental conditions like temperature, humidity, and pressure can influence the
sensitivity and accuracy of measurement instruments.
What does a loop calibrator do?
✔✔A loop calibrator is used to test and calibrate control loops, ensuring that the instrument and
controller work together effectively.
What are some common types of sensors used in industrial applications?
✔✔Common sensors include thermocouples, pressure sensors, flow sensors, and level sensors,
each tailored to specific measurement needs.
What is the significance of safety protocols in instrument handling?
✔✔Safety protocols are essential to protect personnel from hazards associated with operating
and maintaining instrumentation equipment.
What is a flowmeter, and what does it measure?
✔✔A flowmeter measures the flow rate of liquids or gases within a system, providing crucial
data for process control.
2
,What is the purpose of using a pressure gauge?
✔✔A pressure gauge measures the pressure of gases or liquids in a system, helping to ensure
operational efficiency and safety.
What factors can affect the accuracy of an instrument?
✔✔Factors such as temperature fluctuations, humidity, electromagnetic interference, and
instrument calibration can all affect measurement accuracy.
What is the difference between an analog and a digital instrument?
✔✔An analog instrument displays readings using a continuous scale, while a digital instrument
presents measurements in numerical form on a screen.
What does a temperature transmitter do?
✔✔A temperature transmitter converts temperature measurements from a sensor into a
standardized output signal for monitoring and control purposes.
Why is it important to document calibration results?
3
, ✔✔Documenting calibration results provides a traceable record that supports compliance with
regulations and quality assurance processes.
What is the purpose of using an oscilloscope in instrumentation?
✔✔An oscilloscope is used to visualize and analyze electrical signals, helping to diagnose issues
in electronic circuits.
How does a liquid level sensor operate?
✔✔A liquid level sensor detects the level of liquid in a tank or container, providing critical
information for process control and inventory management.
What is a signal conditioner, and why is it important?
✔✔A signal conditioner processes the output from sensors to improve signal quality and
compatibility with monitoring systems.
What is the significance of routine maintenance for instrumentation?
✔✔Routine maintenance is vital for ensuring the reliability, accuracy, and longevity of
measurement instruments.
