BV is
- A.
Ball Valve
- B.
Butterfly valve
- C.
Basket valve
- D.
Bolt valve
Correct Answer
A. Ball ValveExplanation
The correct answer is Ball Valve because it is a type of valve that uses a ball-shaped disc to control the flow of fluid through it. The ball has a hole or port in the middle, which allows the fluid to pass through when the valve is open. When the valve is closed, the ball is rotated to block the flow, providing a tight seal. Ball valves are commonly used in various industries due to their durability, reliability, and ability to handle high-pressure and high-temperature applications.Rate this question:

SS means
- A.
Stair stack
- B.
Simple Stack
- C.
Stainless Steel
- D.
Simple Steel
Correct Answer
C. Stainless SteelExplanation
The abbreviation "SS" commonly stands for "Stainless Steel." Stainless steel is a type of steel alloy that contains a minimum of 10.5% chromium, which provides it with excellent corrosion resistance. It is widely used in various industries, including construction, automotive, and kitchenware, due to its durability, strength, and aesthetic appeal. Therefore, in the given options, "SS" most likely refers to stainless steel.Rate this question:

Basic instruments are measuring in the range:
- A.
0-20mA
- B.
0-10mA
- C.
4-20mA
- D.
3-15mA
Correct Answer
C. 4-20mAExplanation
The correct answer is 4-20mA because this range is commonly used in industrial applications for measuring and controlling analog signals. The lower limit of 4mA ensures that there is a minimum current flowing through the circuit, even in the presence of noise or other disturbances. The upper limit of 20mA allows for a wide range of values to be measured accurately. This range also provides a clear distinction between normal operation (4-20mA) and fault conditions (below 4mA or above 20mA), making it easier to detect and troubleshoot any issues.Rate this question:

What is redundancy?
- A.
It is a phenomenon
- B.
Back up
- C.
Reduce size
- D.
Reduce accuracy
Correct Answer
B. Back upExplanation
Redundancy refers to the act of creating backups or duplicates of data or systems. It is a precautionary measure taken to ensure that data is not lost in case of system failures, accidents, or any other unforeseen circumstances. By creating backups, organizations can restore the data and continue their operations without significant disruptions. Therefore, the answer "Back up" accurately describes redundancy as it highlights the purpose of creating duplicates to ensure data availability and continuity.Rate this question:

Which of the following have redundancy?
- A.
PLC
- B.
DCS
- C.
None of these
- D.
Both of these
Correct Answer
D. Both of theseExplanation
Both PLC (Programmable Logic Controller) and DCS (Distributed Control System) have redundancy. Redundancy refers to the duplication of critical components or systems to ensure continuous operation and minimize the risk of failure. In the case of PLC and DCS, redundancy is implemented to enhance reliability and availability. Redundant components or systems are used to provide backup in case of a failure, allowing the automation system to continue functioning without interruption. This redundancy feature is crucial in industries where downtime can result in significant financial losses or safety hazards.Rate this question:

Temperature can be measured upto______ degree Celcius.
- A.
1000
- B.
2000
- C.
100
- D.
Any value
Correct Answer
D. Any valueExplanation
Temperature can be measured up to any value in degrees Celsius because the Celsius scale is a continuous scale that extends infinitely in both the positive and negative directions. This means that there is no upper or lower limit to the temperature that can be measured using the Celsius scale. Therefore, any temperature, whether extremely high or extremely low, can be measured in degrees Celsius.Rate this question:

Gears are used in instrumentation.
- A.
True
- B.
False
- C.
Sometimes
- D.
Never
Correct Answer
B. FalseExplanation
Gears are not typically used in instrumentation. Instrumentation refers to the use of instruments or devices to measure or control various parameters such as temperature, pressure, flow, etc. Gears are mechanical devices that transmit power or motion from one part of a machine to another. While gears may be used in certain mechanical systems or machines, they are not directly related to instrumentation in most cases. Therefore, the correct answer is False.Rate this question:
